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.

🙂

a short session with the “shredder synth”…

I recently mixed a really interesting session from june 16, 2012, where I did my first ever testing of and recording with an app I had just recently acquired, which is called “shredder synth” – a bit of a misleading name, because it neither shreds (well, it probably can, if you work at it) nor is it a synth – at least, not a normal synth – but nonetheless, it’s a truly remarkable app, and I wanted to share my experience with it with you…

first of all, I cannot for the life of me imagine how the developers of this app even got it to work, because, somehow, from a normal analogue guitar input, they have made a fairly flawless translation to a full on guitar synthesizer – an amazing acheivement for a tablet-based device!

so all you need is an input for guitar (any will work, I happen to use the “apogee jam”, which has worked flawlessly with every app I’ve ever tried it with – and that is several now) and that is all: ”shredder synth”does the rest – it detects the input, and somehow translates audio into MIDI to drive the synth.  god, and the developers, know – I do not 🙂  and I don’t actually care, all I care about is how it sounds – and that is wonderful.

the sounds – are beautiful.  that’s why I say the name of the app is misleading, OK, sure, you can get some heavy/metallic sounds with it, but it’s mostly capable of very, very beautiful sounds, very subtle, or very strange sounds.  the only negative comment I might make is that there are not very many “presets” – but, that’s not really a negative – I just happen to like apps that give me many presets, because that gives me that many more “starting  points” to modify from…but either way, presets or no, this is an excellent application with enormous creative potential.

I find the interface to be really easy to use and understand, it’s very, very simple to edit a voice, and on my very first day with it, I took a standard voice, modified it to my liking, gave it a name, and saved it for future use – a beautiful, beautiful sound, which I then, two days later, recorded two really lovely improvs with. one of those improvs, entitled “a string of islands“, can be found on soundcloud – I am so pleased with this simple but effective piece of guitar – but guitar played through a tablet guitar synth – remarkable!

some of the stock voices are really, really beautiful – one in particular caught my ear, “appalachian” – which is a very pure sine wave sound, with a serious hint of slow attack that gives it a quasi-reverse sound – so it’s sort of halfway between a forwards and backwards guitar sound, but a very, very pure tone indeed, and really works beautifully in any improv or piece that I’ve used it in – a definite “go-to” tone.

I really, really hope that this app does well, because I already like it in it’s current state, but I could imagine, with more features, more presets, and more functions, that over time, it might become one of the most amazing and capable guitar apps anywhere.  I hope the developers will really put some thought into improving this app, and making it truly world class – it’s well on it’s way already

I only have a handful of guitar apps (compared to a ridiculously large number of keyboard based apps I own) and”shredder synth”is utterly unique among them – three of the main guitar apps I use,  are guitar amp/cabinet emulation / effects multi-purpose apps (“stompbox”, “ampkit +”, and “jam up pro xt”), basically, different versions of the more familiar “guitar rig” that appeared some time back: devices to run your guitar through.  and I’ve been astonished at how good some of them sound, right out of the box – replacing thousands of dollars worth of gear with a 20.00 dollar application – that’s astonishing.

I have a couple of other guitar rig type of apps that I don’t really use, like “amplitube” and so on, because the main three I have are so, so capable – really powerful guitar processing devices, particularly peavey’s “ampkit +”, which I absolutely love.  I have high hopes for the newly acquired “jam up pro xt” but it’s a bit underpowered right now – ampkit plus is miles beyond it in terms of devices available and presets available – miles ahead – so I hope “jam up” will catch up 🙂

but, so far, ”shredder synth”is the only guitar synthesizer in the bunch, and it’s a beauty.  what I realised during this session was, that along with all the processing I can do to a guitar signal, using ”shredder synth”means that now…I can drive those processors with two unique guitar synths – the roland gr-55, and, “shredder synth“.

and actually, of course, since the roland is capable of two simultaneous synth voices (and, one modelled guitar voice) that actually means I can have three guitar synths (and one modelled guitar, too!) running simultaneously. 

so I can imagine producing some very, very complex waveforms, with one stereo pair of guitar running from the roland gr-55, and another stereo pair running through ”shredder synth” – and then of course, taking those strange “triple guitar synth” constructions, and then running them through the many processing options…my guitar continues to mutate further and further away from sounding like a guitar – which to me, is usually a good thing!

some of the pieces I recorded in this session from june 16th, 2012, demonstrate this beautifully, and even when there are just two synths running – say, poly sitar from the roland, and digi-lead from the shredder –  it’s uncanny to hear a melody played by two completely different synth voices – especially since in some cases, the differences in adsr, particularly, differences in the attack, mean that the melodies seem to interweave, since one synth voice might “start” it’s phrase many milliseconds before or after the other – a great effect, because even though there is only one note playing, one melody, the aural illusion is of multiple melodies – because the voicings are so very different in their sonic characteristics.

I was astonished to realise that suddenly, I now have an extra guitar synth added to my main guitar sounds – so going from the already very lush combination of two synths and one modelled guitar, to now three synths and one modelled guitar – which while it may not sound like much on paper, in terms of my guitar sound – it’s huge.

given my now-very-flexible routings situation, it will also be possible to route one synth through one set of processors, and the other, through another, and, sending separate stereo pairs to the recorder, as well – allowing me to record the output of the roland on one pair, via one set of processing devices, and the output of the shredder on another, via another set of processors – giving me maximum mixdown flexibility, plus the ability to level match precisely between the two after recording.

one of the test pieces utilised a second app, so as well as”shredder synth”and the roland, I was running a tabla/tanpura drone as a backing track, using my favourite “itabla” application, and that piece, even though just a rough run through, really gave me the flavour of just how good this “two guitar synths” set up is going to be going forward when combined with other applications like “itabla”.

other “shredder synth” presets that merit special mention are “hidden talons” which is almost impossible to describe in words, running a “glass cello” on the roland into the “hidden talons” patch on the shredder, created a complex and beautiful stereo output, with oddly-moving-from-major-to-minor organ chords – plus, strange bubbling sounds, a beautiful drone-like sine wave output – and the constant, gorgeous glass cello driving the whole thing – a really lovely sound (if a bit out of control at times!).

I also am quite partial to the preset “keep your ears” – a sort of oddly-arpeggiated sine wave synth – again, when coupled with a more constant roland voice – the glass cello again – it works really well because the two voices are so very, very different – great sonic contrast.

glitchiness? – well, I’d say, all in all, that the “shredder synth” is about the same as the roland. let’s face it – all guitar synths suffer from this – if you do not hit that note precisely, perfectly, carefully – you get little glitchy sounds sometimes, depending on which voice, and which fingering, and how much care you take in the accuracy of your fingering.  this can be controlled via the application of very precise technique.  sloppy, random playing generally results in a rapid increase in “glitchiness”.

this applies equally to the roland gr-55 and to “shredder synth” – it’s part of the slightly glitchy technology of input tracking – whether that be the roland’s special GK pickup, or. the way the shredder synth’s developers have captured the guitar’s input to use to drive the synth – sometimes, I love those glitchy, weird extra “sounds”, their randomness and sudden appearance can add character and excitement to a piece.  other times, they can and do sometimes annoy me, because sometimes, I really want the pure sound of the patch.  but the “shredder synth” is truly no better and no worse then the gr-55 – it tends toward glitchiness on some voices more than others – as does the roland.

this is something that can probably be improved over time by the developers, but, to be honest – a big part of it is the player’s style – when you start out playing guitar synth, you quickly learn that it’s not “just like playing guitar” – in fact, you actually have to spend time and make a deliberate effort to develop a specific picking style for each synth voice, that works with that particular sound – and every voice has it’s idiosyncrasies, that you have to allow for – and great care must be taken to perform each note so that the device doesn’t glitch.  but – with practice – you learn , and it sounds better and better as you learn more precise fingering which translates directly into better tracking and fewer glitches – usually 🙂  it’s not an exact science, but to me, it’s miraculous that guitar synthesizers, of any description, exist at all…they are an astonishing thing.

hearing this session now, there are maybe only a few viable takes from the session, because the whole idea of playing with two guitar synths at once was new to me, and I just didn’t do that well – I was still adjusting to the double-synth concept – but when I hear the tracks, including imperfections and my own learning curve – I can hear great potential here.  particularly the track I recorded using itabla pro, could easily lead to a whole new kind of guitar-synth-based “synthraga orchestra” piece – using not a keyboard synth, but perhaps the roland gr-55 driving “shredder synth” atop itabla – the potential that these test recordings reveals is really encouraging – and I love the sounds that this unique and interesting application makes.

but the jewel in the crown from this session, are the last two tracks, which were both recorded using the first custom guitar synth voice that I created – so I had tailored an already-beautiful sound to my own ear – it sounded just like I wanted it to – and I was good and warmed up, so, I sat down and did two very, very satisfying and quite beautiful pieces using this custom sound.

that is possibly the most attractive feature of the “shredder synth” though, the ability to create your own synth voices, either from scratch, or by modifying existing presets – and there you have an almost unlimited palette to work from – and I am looking forward to getting creative in this area, creating a number of patches of my own to use in ambient and active pieces of music…particularly ambient, and the custom sound I created is in that category – which is why the last two ambient pieces in the session are so, so successful.

shredder synth” is another real winner in my book, and one of my very favourite guitar apps to date – highly recommended if you want something a bit “different” – and, if you have no guitar synthesizer at all in your set-up – well, if you have an ipad, you can now have a guitar synth for an extremely reasonable price.  it’s not perfect, it’s not as capable as  the roland gr-55, but for the money, it does do an awful lot, and it does give you a lot of really interesting and unusual and also, frankly strange! new sounds for your guitar – you can’t really go wrong!! 🙂
