file restoration – adobe audition – [the perils of digital recording] – from analogue to digital

 

as anyone who has been doing digital recording for any length of time knows…when making digital recordings…shit happens.

  • you experience a drop out during that perfect take, consequently losing that take.
  • you left one of the tracks unarmed, so not everything recorded.
  • You forgot to change the track assignments for one set of inputs, so all of your instruments ended up blended together in one stereo pair, instead of in two nice, discrete, stereo pairs as intended.
  • the levels on one or more tracks were a tiny bit too “hot” so now you have digital clipping in some of your tracks.
  • unbeknownst to you, while you recorded 20 beautiful new pieces of music – each one was being recorded replete with many, many pops and clicks – thanks to any number of digital culprits…ranging from IRQ interrupt conflicts to bad USB cables to just plain bad luck.
  • your daw inexplicably crashes in the middle of that perfect take, consequently losing that take.
  • tracks are inexplicably distorted audibly, while not apparently being clipped – anomalous distortion from nowhere (this turned out to be a slightly overly loud output from a midi instrument, of all things – turn down it’s output, the distortion goes away)
  • you set up your midi and audio tracks the same way you did yesterday, but no sound comes out – even though yesterday, with the identical set up, everything was working fine.  (this most frustrating of problems is quite common with me, and there have been many a session where the first 10, 20, 30, 40 minutes of the session were concerned with getting some sound to come out the daw – any sound, some sound, please…)
  • a solution you found to a problem such as the one above, works on one occasion, but does not work on another, requiring you to find a second solution to the same problem.  (or a third).

the above is just a random selection of negative recording possibilities…(and all of the above have happened to me at one point or other in time!!) but I am sure if I queried ten of my pals who do digital recording, they would all have similar “lists” of what we will call, for lack of a better term, “negative digital recording experiences”, but maybe, it would contain half a dozen other / different problems encountered from the ones I experience, or a mixture of these symptoms and others unique to their systems.

and each system is unique, and idiosyncratic.  I know this because I have two supposedly matching daw installs, one on a desktop and the other on my laptop – and the daws behave differently on the two machines (I kid you not).  not in any serious way, but in a lot of little annoying ways…for example, if I record a session on the PC in my studio, and then try to open that session later on the laptop to mix it down – it won’t open until I accept a message about a missing plug-in that I don’t even use or know what it’s for.  that means, every single time I want to open a PC session on the laptop, I have to use the SHIFT key method to open it in safe mode. ridiculous, but true!

 

but today I want to talk about the amazing fact that in this day and age, with the right tools, audio that is seemingly irreparably damaged – can not only be restored, but if you are careful, can be restored to a state of near pristine perfection.

back in the days of “tape recorders” – and I moved from many years of working almost exclusively with my teac 3340S 4 track ¼ reel to reel machine to using cool edit pro on a late 90s pc clone – if something went wrong on a take – that was pretty much it – sure, there were a few tricks that could be used, none of them easy to implement, none of them particularly effective – generally, you just had to erase the track and re-record a new take.  or, if you were very adept, very patient, and very lucky, you MIGHT get away with “punching-in” small sections of music, to replace problematic sections.  possibly.  more likely – no, punch-ins just didn’t fly.

if, for example, you experienced random pops or clicks, or, if you had your levels too hot, and tracks subsequently ended up clipped or distorted – again, that was it, there were not any tools available to repair such damage, so you had two choices: play that impossible part again, or try to disguise the damage somehow.

neither method was very successful, and occasionally, because the take was impossible to “re-do”, I would just leave it, pops, clicks, and all, in the song, mix it as well as I could, and hope that the musical brilliance of the piece would somehow mask the giant “pop” at 3:51.  usually though, I just erased that perfect take, and played a less perfect, but adequate, “popless” take.  the problem being, with only four fragile channels of audio on 1/4 piece of tape – the only way was “destructive” – delete that take, and re-record it over the damaged one.  and if you didn’t play it as well – oh well.

so recording on tape was all about being very lucky, about sometimes, nay, often, having to compromise – either by accepting a really good take with technical imperfections like pops, clicks or mild clipping – or, by erasing and re-recording something that was not quite as good, so you could get rid of the pops, clicks or distortion – but then, having to accept a “lesser” performance for the sake of getting rid of the pops…

recording on tape was often all about compromise, about making the best of a bad situation.

 

fluffed one note in a seven minute piano piece?  well, if you were very, very skilled, you might be able to punch-in a replacement note or phrase on another track (assuming you had one available!) – or, possibly, not – which means basically that you have no choice but to go back and record the entire seven minute piece again, without fluffing that note.

(of course, now, if you did this same recording as midi, you could just go into notation view, find the “wrong” note, and correct it – but I am talking strictly audio / analogue recording here).

for years….this was just the way it was.  punching in rarely worked for me, it’s just not ideal, and for me, every recording where I did punch in, when I hear the mixed track played back…all I can hear is the part that’s been punched in.  it sticks out like a sore thumb to my ears, it interrupts the flow…it’s just not the best way – it’s really better, always better, to get the whole thing in one single take – it really is!

but…we were used to these “rules”, the “rules” of the golden age of home recording, where you “bounced” three tracks down to one so you could free up the three for overdubs – meaning you had a sub-mix that was carved in stone, that you could never, ever change – and that is maybe the worst part of recording on tape, or rather recording on a four track! – it was very difficult to go back and fix anything; you had to accept compromises; and; if you wanted more than four tracks – you had to “commit” to one sub-mix of instruments.

so for all the problems that I’ve had with digital recording, I have to say, it’s still preferable to the tape days for one reason:  now, with existing technology, most of the problems I described above (excepting the true “operator error” ones – if you didn’t arm the track, and it didn’t record, I am afraid I cannot help you!), actually can be fixed.  with astonishingly good results.

over the past three or four days, I’ve been working on a digital restoration project, using my newly-acquired adobe audition version 3.0.  I had nine tracks, recorded on the ipad when I first got the “addictive synth” application, from a 20120407 session, and I felt that some or all of them were good takes – but, unfortunately, due to the above-mentioned irq interrupt problem – they all ended up with pops and clicks throughout.  lots of pops and clicks – perhaps as many as 60 or 70 in a single four minute track.  since I’d recorded them “live” by playing the ipad and recording in SONAR – all the pops and clicks were recorded along with the audio.

at the time, I attempted repairs using several tools, but to no avail – until my friend and business partner ken mistove suggested adobe audition.  since then, I’ve actually acquired a copy of audition version 3, that adobe, strangely, is currently offering as a free download – along with early versions of photoshop, elements, acrobat, go live, illustrator, and premiere pro ! so now this very excellent multi-track audio and midi recorder is part of my permanent daw set-up, and I am seriously considering abandoning sonar 8.5 – possibly.  we shall see.  sonar does have some great bespoke synths, and some fabulous mix plug-ins, too, but I am not sure if I would miss them that much…

there are many reasons I would consider this, for one, adobe audition is the successor to the original audio tool I used when I first “went digital” back in about…1998 ? – cool edit pro.  so for one, it’s like getting an old friend back – except, an old friend who has had a serious face lift and restorative surgery.  for another – adobe audition has a “healing tool”, which works very, very well for healing and totally removing pops and clicks, without damaging the underlying audio (assuming you are careful and take your time!) but not only that – much to my amazement, the same healing tool can be successfully used to heal distortion – so, my previous restoration project to this one, was recovering a number of tracks that had clipped audio on one of the tracks – again, as with the nine pieces I just restored of addictive synth and animoog synth tracks, saving some good tracks that otherwise would have been lost.

for yet another, audition has true fft style noise reduction, which I love, and I had sorely missed when cool edit disappeared – in fft noise reduction, you take a “sample” of the noise you want to get rid of, then apply a fix based on that sample – it “finds” noise like the sample, and…removes it.  brilliant!

I knew audition could heal pops and clicks, because I had used a trial version of it some months back to do just that.  but I did not know until very recently that it also can heal clipping – and I found that to be just astonishing. thinking back to the tape recorder days…if you had clipped audio – there was literally nothing you could do, the tracks were ruined, rubbish – there was no fix for clipped audio that I ever heard of – that was that, your tracks were useless, discardable.  your ONLY option – reduce the level, record the track over.

 

not any more,  not in the brave new digital world – now, clipping can be removed as easily as the pops and clicks can be removed.  I find that to be utterly remarkable.  I have already recovered damaged tracks from two sessions, about 17 or 18 tracks in total I think; half pops and clicks, the other half, clipped audio – and next, I am going to look at a session with 20 tracks (as mentioned above) that also have pop and click damage – these are “audio only” tracks made with the animoog, some of them quite beautiful, so I wanted to try and save as many of them as I can.

so far, when I have set out to recover tracks using adobe audition, I have managed to save every single track I attempted to save – I have 100% success rate, for pops, clicks, and clipping.  that is also quite remarkable, but, I am fortunate, I’ve been fortunate.  it takes a lot of patient work, to sit through and manually remove each click, pop, snap or bit of clipped audio, and in some cases, I had to make perhaps 50 or 60 “auto-heals” to a single track to rid it of all pops.  you also have to be very careful with your auto healing, because it can slightly damage audio – but if you are very precise, use the smallest brush size possible for the pop, you usually end up with undamaged audio.

this also means, when I finish the next session, that I will have recovered something like 40 tracks, that in the tape recorder days, would have been written off as unusable, with no hope for repair – tracks that were literally brought back from the dead, as it were.

that is the good news.

the bad news is, it takes a long, long time to repair multiple pops, clicks or clipping; you have to be very patient, you have to be very careful (because it IS possible to damage the underlying audio) so what I do is I check each repaired pop or click by immediately listening back to it, to assure myself there is no audio damage.  that really slows down the process, but, avoids any problems with damaged audio.

so for this last session, where I had nine tracks – five addictive synth pieces, and four animoog pieces – I probably spent something like six or seven hours, over a period of perhaps three or four days, working on them.  just now – I just played them back on headphones, to listen very, very carefully to the results – and, for all nine tracks, there are absolutely no hints of any pops or clicks, and no sign of any audio damage at all – they are now very near “perfect”, they sound great, clean and tidy, and I cannot believe that a week ago, they were consigned for destruction.

how brilliant is that, really?  I think this is one of the true miracles of digital recording, like undo and redo, the ability to repair damaged audio that was previously considered to be utterly unrepairable.  that’s astonishing !

younger musicians will probably take this kind of thing for granted, but for older musicians such as myself, who grew up in the era of the “tape recorder” – these tools and processes are nothing short of utterly miraculous.  also, as time goes on, and I listen to old recordings made on the teac 3340s four-track recorder, from the late 1980s and early 1990s…well, to be totally honest, I can’t remember, and I cannot fathom how I actually did it, I can’t really understand how I made it work without any digital tools!

miracles were performed, amazing “fixes” and punch-ins that were true feats of audio engineering – all of that bravado and skill, now made redundant, now just about completely unnecessary – because of the powerful tools built into programs like adobe audition.

I would also say, that as a recording tool, it’s very, very slick, I am falling in love with it all over again, as I fell in love with the power of cool edit pro back in the day.  it has a lot of great built in tools, including amplitude and frequency analysis, not to mention a lot of really quality built in effects – I am really loving it so far.

I was spoiled, I was using the current version of audition (5.5, I think), on a trial basis, and then switched to this free version 3 – and, it’s maybe not quite as fancy – but functionally – it’s not really that different.

after a few days of using adobe audition version 3 – I am not missing the newest version any more, and I am very happy indeed using this “old” version.  it does everything I need, without the slightly over-engineered clutter of a sonar…

digital recording can be very frustrating, it really can, and you can have so many problems with it, that sometimes, you long for the simplicity of that tape recorder.  but…not me – I love digital recording, I don’t miss tape recorders, with their fragile tape, and rigid rules – so much can go so wrong, whereas in digital, if you are patient, and your system is stable – much, much goes right.

as far as the famous “digital” vs. “analogue” argument – well, I am all for a good bit of “tape warmth” but for me, the only realm where that matters is guitar amplifiers – they should have valves (tubes) in them, because for guitar, analogue/warm is better!  but for the kind of music I play (mostly) quiet, very quiet, and quieter still, the digital realm is a much better one for me, because I can remove hiss, hum, pops, clicks, clipping and anything that gets in the way of the music…and digital does just capture the music, with no added harmonics from “analogue warmth”.

sure, I loved hearing my records on valve (tube) stereos and they did sound cool, and if I could afford one, I would buy one of those retro valve stereo systems that are about nowadays.  I would also buy about ten different valve (tube) guitar amplifiers, too, including marshalls, fenders, and vox – not to mention, line 6, roland, pignose, and a few others, too!  these require space and money…two commodities always in short supply.

but for recording clean, looped energy bow guitars in a big “reverb” room – digital is the way.  if I were doing a lot of really distorted guitar, if I were playing rock or metal music, I would absolutely look to valve (tube) amps, but on the other hand, digital modelling has come a long, long way, and some of the amp “models” I have in some of my guitar applications, rival the real thing for amazing sound.  as proof, I offer up my “gone native” album – every guitar sound is either a guitar synth, modelled guitar from the guitar synth, or modelled guitar from my line 6 x3 live – there is not a single “real” recording of a guitar through an amp on the record.  and yet, if I didn’t tell you that – if you listened to the entire “gone native” album from start to finish – you would swear you were hearing guitar x through amp y.  but – no, it’s all modelled, and if you work with your models, you can get some amazingly realistic guitar sounds.

analogue purists and my old friend, neil young, will disagree with me, but seriously, if you think about it, a recording played back through an analog valve (tube) amp will have a certain waveform, rich in harmonics.  the same recording, played back through a solid state, digital system, will have a slightly different waveform, with fewer harmonics, actually representing the recorded sound without any additional colouration (which is what tube amps add to music – harmonics, colour, richness).

but either of those waveforms can be modelled, so the best modellers set up the real amp, with the real microphone, and use real guitars, to get the real, right modelled sound for tube amps.  eventually, as modelling technology improves and improves, it will become impossible to distinguish between a “real” recording of a les paul through a marshal, and a “modelled” recording of a les paul through a marshall.  I think that in some cases, the modelled sound already matches close enough to fool the ear.  as example, I would point to my song “caladan” from “gone native” – this track features classical instrumentation, which augment a dual nylon string classical guitar solo.  which when you listen to it – well, that’s what it sounds like.  however – every sound in that track, except for the drum track – was made with the remarkable roland gr-55 guitar synthesizer – and to my ears, those “nylon guitars” you hear me playing during “caladan”…SOUND like real, nylon string classical guitars.  again – if I had not told you it was a synth – you might never have realised.  so modelling has become quite adept at fooling the ear, I believe.

 

I’d say it’s near impossible to discern the difference now.  also, my guitar synth has an amazing “les paul” type sound, which is pretty damn accurate.  which saves me a few grand that I don’t have anyway (for that les paul I have never owned, and never will, simply because I can’t afford a les paul!).

 

don’t get me wrong, I love valve (tube) amplifiers, for guitar, or for stereo – I grew up in the valve (tube) era, and my personal preference will always be a strat plugged into a marshall or a les paul plugged into a vox ac-30 or a fender super reverb  (god I miss my super reverb!).

 

that’s an irresistible sound, it really is.  but – technology is really catching up, modelling is getting much, much better, and it’s even got to the point where I’ve done some loud guitar improvs, using patches that involve modelled tube amps – and if you close your eyes and just listen – it’s not that easy to tell that it’s modelled…because even though it’s created digitally, it’s an exact match of the captured waveform of the analogue set up, so to the ears…it sounds like the warm, analogue guitar sound we all dream about.

nearly indiscernible from the real thing already, in a few years, even the most hardened “analogue purists” will be truly put to the test, because they will no longer be able to tell what is “real” analogue warmth as opposed to “modelled” analogue warmth.  I already really can’t tell, and as I said, I’ve done some recording using ampkit plus on the ipad, that when you listen to them in headphones, you would swear they were made with a guitar plugged into a tube amp.  seriously.

I am personally amazed by the way digital devices of all types mimic “analogue” sounds, even a first generation device like my now-ageing line 6 dl-4 delay pedal – it does some amazing tape echo sounds, and you can even dial in how much analogue “sound” you want for your patch – in fact, most of the best sounds on the DL-4 are modelled after tape echos, valve (tube) echos, and other ancient tech that just sounds good – but in that case, it’s digitally-recreating something that was originally created with some cumbersome and unreliable hardware (tapes and tubes, I am afraid to say!).

I know this first hand, because I used to own a tape-based echoplex – and that thing was a mechanical monstrosity!  frankly, it was terrible – sure, it sounded awesome, but it was noisy, unreliable, prone to jamming – it was not the best piece of tech ever imagined.  but – line 6, when creating the dl-4, modelled this type of echo unit beautifully – so you get the great analogue echo / delay sound, but in a much, much smaller box that is not nearly as prone to breaking, not nearly as idiosyncratic, as an original echoplex was!

it’s very odd thinking back to using that, it was the first delay device I ever owned, and I can remember playing my guitar through it when I lived in a place called fletcher hills, when I was about 15 years old – in fact, that’s where I met one of my oldest living friends, jim whitaker, a guitarist from whom I learned a lot, we made a lot of recordings together and played quite a few gigs together, too back in the late 1970s.

 

at that point in time, if you were a guitarist, your main sound-producing tools were:

a guitar

a guitar amplifier

and that was that.  if you were really forward thinking, and wanted to have a huge palette of amazing sounds, you would expand this first like this:

a wah-wah pedal

a fuzz box

and then finally, going completely mad here, like this:

echoplex tape delay unit

 

so the guitar was…originally a no-name, red, semi-hollow f-hole electric, then, a three-pickup vox bulldog (god I wish I still had that ugly old guitar!) and then finally, a fender jaguar (god I wish I still had that beautiful old guitar!).

with these five items, you were fully prepared as a guitarist.  in my case, the wah pedal was a vox clone, made by thomas organ (who bought the vox wah line, I think) and the fuzz box was a very used, very beat up original red arbiter fuzz face that joe norwood very kindly gave me (probably because it sounded horrible) – frankly, I don’t know how jimi got it to sound so, so good (probably something to do with the stacks of marshalls that I never had!) – because I never could.  (you can hear this actual fuzz unit on a track I recorded with my best friend, the late ted holding, when we were about 15 or 16 years old, entitled “froggy’s holiday” – an instrumental, and during the song’s chorus, you can hear me clicking the fuzz on for my lead guitar part) – it was a pretty rough sound.

 

when I compare and contrast this utterly primitive set up, circa 1973, to my current guitar set up –  2013 – exactly forty years on – well, let’s just say, my 15-year old self would not have believed what can now be achieved with live guitar – imagine, such things as guitar synthesizers, looping, ebows, and reverse guitar – most of which, simply did not really exist in 1973, except perhaps in the very most expensive studios.  so if I could have seen myself, from age 15, watching my 50-something self do a live loop with a guitar synth, playing oboes, flutes, and clarinets from the guitar fretboard, and recording and layering them live with a magic looping box – I simply would not believe my eyes or ears.  that is how far guitar tech has come in forty years.

 

a sound as incredible and as exotic as reverse guitar, on the other hand, could only be achieved back then, by turning a tape over and playing forward against the running backwards track, and then turning the tape back over – trial and error style.  so to have a device like the line 6 dl-4, where with one button push, your guitar is playing backwards, live…that would have been impossible, voodoo guitar magic of the most extreme kind imaginable.

jim whitaker and I would not have believed it – and in fact, I still kinda can’t believe it.  I really can’t believe the rich and varied palette of sounds, and sound modifier, that I have to hand – it’s just amazing what technology can achieve now, it really, truly is.

in summation – analogue, tape recorders, and antique guitar gear all have their place, but there is no sin in using the very reliable, very clean world of pristine recording offered by digital recording – and, you can even save your “irreparably damaged” tracks – which I still find to be absolutely astonishing.  for that alone, it’s worth paying the price of “the loss of analogue warmth”…which, as time goes by, that “price” diminishes each year, as modelling tech improves year by year.

possibly the most interesting observation I might make though, is that regardless of the state of my own personal guitar set up, or recording set up – is the fact that whether it was my 15-year old self playing guitar through a real tape echoplex, or, my 25-year old self playing through my first digitech rack mount multi-effects unit, the DSP-128, or, my 35-year old self playing guitar through multiple loopers such as the oberheim echoplex pro and the roland rc-50 looper through complex, multiple-path live guitar set-ups, or…my 45 year old self playing through state of the art modern stomp boxes such as the digitech time bender and doing post processing with a quality digital reverb such as breeze…or, my 50-something-year old self, playing through eventide space, the top of the line reverb available in a stomp box – no matter which of these “dave staffords” was playing through “what guitar rig” into “what tape recorder” or “what sound card”…the main thing is, I always, always, am totally immersed in the experience – I love playing the guitar.

and that is something that time, nor technology, will ever change…if I went back to guitar, amp and wah pedal now – I would make the best of it, I would have a go at “the burning of the midnight lamp” or “voodoo child (slight return)” or “white room” – all songs I’ve played over time – or something where the wah pedal would “work” as the sole effect.

why not – it sounded good then, it will still sound good now – which just goes to show, it’s not really the tools you have, it’s how you use them, that truly counts.

something that eno said has really stuck with me over the years, he was talking about synthesizers and how they give you too many choices, too many sounds (and I agree with that view, actually) and he was talking about the yamaha dx-7, and how in his opinion, it had a very small handful of really, really good sounds that it made, and the rest were dispensable.  he would rather just use that one good sound,  the one really good sound, than switch between 10, or 100, bad sounds.  I call this “the eno principle”, and each time I assess my collection of sound-producing devices, I make a conscious effort to PARE DOWN to only the sounds that are the best – and not use the others.  it’s hard work, but you should stick with what sounds good – and avoid presets or patches that don’t totally en-thrall you.  too much choice is sometimes not so good…

eno noticed then, that some devices did one thing particularly well, so he would just use that device for that one purpose, rather than any of it’s other possible uses – use it for what it does best.  and that makes sense to me.

so over the years, whenever I get a new instrument or effect, I always try to identify the handful of sounds it makes or processes that are truly, truly amazing or beautiful – and I then pretty much only use those sounds.  I used to use the dx-7 in performance with bindlestiff, and it had about 8 sounds that I really loved, so in every gig, when I played the synth, those were the 8 sounds I would use. the other hundred odd sounds – rarely were used or heard.

 

In the same way today, in the studio, if an instrument or effect has a truly, truly beautiful sound – then I use it, and I use it repeatedly – because it’s good!

 

 

one current example of that is the line 6 dl-4 delay – I have more than one delay, and since I have the digitech time bender delay which is smaller, more compact, more modern, and more capable – I’ve decided to let the dl-4 do what it does best – reverse guitar.

so – the dl-4 stompbox is now on one of the ancillary “lines” going to one of the mixers, and it’s set to reverse guitar – so when I switch to that line, I get – instant reverse guitar – it’s always there, it always sounds beautiful – and I don’t have to then spend time calling that sound up on the time bender, or on any of the other devices I have that might also produce it.  so I’ve taken the dl-4, picked one of the very best sounds it makes, and dedicated it to making just that beautiful, reverse guitar sound…why not?

so these great sounding patches or effects become the unique musical language that defines you, certain “set-ups” become “your sound”, and in my case, an ebow guitar (preferably a guitar with humbucking pickups), with the tone control on the guitar turned off, into a clean, reverb room, looping with the roland rc-50 looper (or any looper) – is very much a “dave stafford” sound.  that simple, simple “set-up”, is basically what I used to make the entire album “the haunting” – simplicity itself – clean, clear reverbed guitar, energy bow guitar.

as another example, the roland gr-55 guitar synthesizers’s “go to” sound is absolutely, without a doubt, “rich strings” – which I return to again and again, because it sounds really good, and, it works really well in loops – so it’s a perfect candidate to become a standard “dave stafford” sound…again, why not?

of course, I do use “other sounds”, and I do look at, work on, and conjure up lots of new sounds to try out – always.  and occasionally, I hit upon one, a combination of guitar synth, guitar, and effects, perhaps, that I really, really like the sound of – so I remember that one, so I can use it again.

this current world of digital recording, the digital here and now…to that starry-eyed 15-year old jimi hendrix wannabe, would have been an impossible, unbelievable world – not real, not possible, totally unbelievable.  yet, that same boy is still here, and that imaginary digital world, where backwards guitars were magic, has turned out to be true – but I still can’t believe the sounds that can come out of an electric guitar – it’s absolutely unbelievable.

I’m sat here listening to some eventide space demos that I recorded in december, and a piece entitled “nature’s wrath” has come on – and it’s simply, the weirdest, most shocking, craziest guitar tone I have ever heard in my entire life.  it is a reverb with a large component of very warped time and a lot of distortion – an amazing sound.

I think it’s one of vernon reid’s “artist presets” but whatever it is, when you manipulate the expression pedal as you play, the stereo sonic smack effect is unbelievable – it’s based on the reverb model “mangleverb” so that gives you a hint, and distortion is a major component in the reverb sound – to me, it’s just astonishing that such a patch can even exist.  playing through it – well, that’s an experience once again…and, an experience that the 15-year old dave stafford could not have even imagined.  but here he is, somehow, in 2013, travelled forward in time – playing that sound, making the magic sounds that he would have once thought to be completely…impossible!

so – forty years – from analogue to digital – from real instruments to ipad applications – from primitive to modern – it’s been a long and interesting journey, and I cannot wait to see, and more importantly, hear, where the next ten, twenty, thiry years of technological advances will take we musicians…but wherever it is, I want to go !!!

I cannot wait.

the return of adobe audition / guitar synth sessions

over the past few days, I’ve been involved in mixing tracks from a live improv guitar synth session recorded way back on february 26, 2012, and it’s been a challenging and interesting session indeed.

first of all, I am using a different tool for the final mixes, a tool I’ve used before, but now, I am sure that I will eventually invest in, instead of trialling it, and that is adobe audition 5.5.

when cool edit pro disappeared way back when, i’d heard vaguely that it had been taken over by adobe, and that’s welcome news, but I didn’t really mean to wait ten years to check out what adobe had done with the cool edit pro code…but basically, that’s what happened.  I’ve been “making do” with other audio tools in the interim, sonar, sony sound forge, t-racks 3, and so on – so imagine my astonishment then, at seeing just how very far the original excellent ideas that cool edit pro espoused, have been carried through, brought up to date, and even into the future, by adobe with audition.

for audio – this is just heaven.  for the first time since the cool edit pro days, I can do noise reduction properly – fft style! – by taking a sample of the noise I want rid of, and then applying that to the track or section I want to clean.  there were some strange residual artefacts in some silences in take 9, the take I’m currently working on – and audition’s fft-style noise reduction cleaned them perfectly.

then there is the amazingly efficient pop removal tool, the “auto healing” brush.  I’ve tried a lot of different methods of removing pops and clicks over the years – and this one actually works.  it takes a bit of practice, but if you are careful, you can totally remove every pop and click without any damage to the actual music.  it’s a visual system, and it works really, really well.

for just those two practical, sensible tools, I am already sold, but then last night, I was trialling many, many echoes, delays and reverbs in the tool – and for built in effects, they are just outstanding.  I’d also already had a really positive experience using audition during the final mastering of “gone native” – using it to measure the effective levels, using the really sophisticated and most excellent analysis tools, so I could gauge the best levels for the tracks on the record – that was an invaluable help at the time.

not to mention, multiple levels of selectable undo – listed right there for you to choose from.  brilliant!

I still have a couple of sessions that have disastrous pops in them, which I never had time to cleanse when I had the trial of audition earlier this year, so for me, just for the effective pop removal tool, it’s a no-brainer.  but it’s also a great, great tool for editing audio, making mp3s, etc. – it pretty much does it all.

this is the first time in a long time that I’ve mixed something outside of sonar, and I wasn’t really missing anything, sonar does have some nice plug ins, but from what I understand, audition supports vst as well, so I am going to be trying out breeze and my mellotron and so on to see how audition does with them – watch this space.

I could also switch to a hybrid scenario, where I record in sonar, apply any plug-ins or reverbs I need, deal with any midi tracks, and once I have a decent sub-mix, send it to audition (which I can actually, probably, just call from sonar – so no need to export!) for final touches.

I got excellent results, and in fact, I ended up doing two additional mixes of take 9, to test out the effect of different delays and levels of reverb on the track, and in listening to the mixes today, it’s done a great job – I am particularly pleased with how well the fft style noise reduction cleaned up those strange noises in the silences, that is fabulous, that was something I loved about cool edit pro, and in fact, back in the day, most of what I was doing was converting master reel to reel tapes of either dave stafford solo albums, or bindlestiff/band albums, to digital, the very first thing I would have to do would be take noise samples (I ended up with a big library of fft files by the time I was done!) and noise reduce the entire master just to get rid of all the hiss and noise from the tape…and it worked beautifully.

so to finally have that tool back, configured the way I prefer (even better, now) is invaluable to me, and, with all the unfortunate popping that I’ve  been cursed with this year in particular, on sessions that are very important to me, I am equally enamoured of the most excellent pop removal tool – I love it – I am absolutely loving adobe audition.

this will probably also mean that I don’t need to use sound forge any more, because from what I can tell, audition is superior in almost every department – including specialised, extensive analysis tools, another huge plus in my book.  I also love the little “instant level” adjuster, a tiny digital potentiometer that hovers in every track, and you can instantly raise or lower the level in db for any section or the whole piece on the fly – a little too quiet?  tweak the pot, and it ups the level, and saves the file – all without bothering you.  that’s a brilliant idea, leaving me free to get on with the work – no dialogue necessary for this most basic of functions!  excellent.

anyway, the track I’m working with had quite a few challenges, I feel it’s an interesting track, it’s certainly imperfect, as improvs often are, so I used the tools in audition to try and improve the parts of the song that I felt were not 100% up to scratch, and mostly, what I’ve  done has really, really helped the track a lot.

I had originally intended only to release one improv from this session, take 10, which is now retitled “extreme gradient” but I went back and listened to the entire session, and the somewhat raw take 9 – which has now been retitled “provide the spark” – leapt out at me as being a strong contender – because of a unique and bizarre accidental “introduction”.

a fragment of a loop got caught in the looper, so this was a short sound, with a gap in between it, a short duration event in a short loop.  it was playing along, so I just let it play, and instead of clearing the loop and starting the take, for some strange reason (none of the other 17 takes have this intro) I decided to just overdub this running loop, and then launch into the song proper.

so as this short sound was repeating, I started inserting short bursts of guitar synth, two notes, one note, on top of it, in successive iterations, and very quickly built up a strange, strange “mini-loop”, with a gap in between, that continued to repeat right up until the point, about a minute and a half or so into the piece, where I then started to play the main improv I was working on that day.

at first I thought, this is just too strange, I am not sure I can actually use this for a video, but as time went by, I “got used” to this strange introduction, so I decided to work up the track in a mix and see what I could do with it.  one aspect of the loop was that it went on a few bars longer than I would have wanted, so to try and add some variety, I used audition to add in a nice delay about half way through the iterations, and then a more extreme delay towards the end – I took a preset delay called “delicate whispering” and altered it to fit the time signature of the piece, eventually (after many attempts) getting the right delay sound – not too overbearing, but enough to differentiate the final iterations of the loop from the first ones – and I think I have succeeded.

as often happens with loops, they can sometimes grow too loud too quickly, so again, I was able to “grab” sets of iterations, and selectively lower their levels (by grabbing in the gaps around them) so that the whole level of the looped section became more even.

the final tweak came at the end of the song, where I originally meant to have a sort of xtc/”great fire” gradual move from dry to reverbed, but in the end, while I did do a variation of that, I actually reverbed different sections of the final guitar solo with different levels of reverb, which had the desired effect – again, trying to instill some variance in this section of the song, and sometimes a bit of reverb is just the thing.

so there is very dry guitar, very dry guitar synth, and then very wet guitar, and very wet guitar synth – lots of variations – which you kind of need on a track where basically, I am playing a lead solo throughout the track – without variations, without a bit of delay and reverb to break things up, it would have sounded like a four minute fifteen second guitar solo – prefaced by a long, strange loop. (of course, that is what it really is, but hey!) – I think I have altered it just enough to make it interesting, and improved it’s user-friendliness a hundredfold in the process…and that’s all thanks to audition, and a bit of creative thinking – and, the tool is so intuitive, so easy to use – of course, probably since it’s the descendent of cool edit pro, I still recognise it’s functions, but it’s so completely different from cool edit pro that actually, it’s almost unrecognisable as ever having anything to do with cool edit pro – stripped down, rebuilt from the ground up – as with many adobe products – this one oozes pure class.

having said all this, I still have a third option with this strange loop – to release the untreated version.  my main motivation for working on the alternate mixes of “provide the spark” was more about learning more about audition and what it can do, and I had a great time trialling various excellent echoes, delays, and reverbs – I had a blast, and it even boasts successive equalisation of repeats in some of the more complex echoes, delays and reverbs, not to mention – of course – 5.1 reverbs, which can be customised for the 5.1 environment! I’ve  never seen a 5.1 reverb until last night – wow!

so in listening this morning, I am comparing my original “dry” mix, which uses only the effects present in the live/looped performance (which were considerable, by the way), to two different alternate versions that had been noise reduced, levels adjusted, delays and reverbs added, and trying to decide what makes the most sense for the video.

after listening to all three mixes a few times this morning, my view so far is this:  it’s between the original untouched mix, and the second delay/reverb mix – the first delay/reverb mix has too heavy a delay on the last section of the loop.

I think in the end, I may start again with the untouched loop, and do just the noise reductions, and the level adjustments on the loop – and some very careful reverbs at the end – and see where that gets me.  if still not satisfied, I will then approach some kind of delay on the last parts of the loop, similar to the on in “version 3” that I am favouring at the moment.

I believe what this means is that, after two nights of work, that I am still not happy, and I want to take more time and see if I can get a “best of all worlds” mix – addressing the needs of the loop, and of the main track, effectively.  I am getting close, and these rough mixes are certainly helping me gauge what else I might need to try…

luckily, I now have a great tool on hand to mix with, well, I actually have several great tools, and that’s the beauty of having daw, you have lots of options – within sonar itself, I have so many mix options, so many plug ins, it’s not funny, and then on top of that, I have several external tools, of which audition is just one, to aid in getting the best sound possible…so I feel totally spoiled for choice.  I also have the t-racks system, which I have yet to explore…

audition is a definite new year purchase, meanwhile, I plan to use my current trial version for another few weeks to clean up some sessions that have been patiently waiting for me to do just that – in particular, a really good session with the ipad from april 7, 2012, demonstrating the amazing power of some of the synthesizer apps, ended up with a lot of pops due to a usb conflict, so I had to shelve several really promising tracks that should have been made into videos for the applicationhd channel – well, hopefully, if I can clean them up, they now eventually, better late than never, will be.  I really want to get those tracks out there as they are really remarkable, albeit currently spoiled by many, many pops. (note: in the interim, all of these tracks have been cleaned up and are now pop-less, and are ready to be released!).

this and another session (at least – probably more sessions that I don’t know about yet, as my backlog is still quite extensive at this point in time) are plagued by pops and clicks, and I am sure that here and there there will also be other clicks and pops, and if I end up buying audition, then I need never worry about that again – I have the perfect tool to sort those out (not to mention, I can use it on the audio from old tapes of every description, even vinyl noise – I can clean up anything with this suite of tools).

once I get back into digitizing tapes (a room full of cassettes and tapes awaits me, as always) that fft style noise reduction will also give me great value, so I can reduce noise and remove clicks and pops…

the current version of audition is pricey, yes, but to my mind, it’s worth it for the time and trouble it will save in cleaning up “difficult audio”.

and I seem to have rather a lot of that about the place.

 

while I certainly have no lack of music to work on, I will say, it’s remarkable to have such a capable and diverse tool set with which to restore and improve audio.  I am loving audition – in any of it’s versions, right back to it’s genesis as cool edit pro 🙂
