I wrote about sourcing sounds for composition. There's obviously more to it than simply recording sounds or events. The whole process is anthropological and therefore complex. When it comes to editing and processing these recorded sounds things are, on the face of it, much simpler.
I transfer recorded sounds from the recording device to the computer then I edit them and compose using software applications. I could equally do this on a multi-track analogue tape recorder and I know some composers who still do. First I use Steinberg's Wavelab to listen back to the sounds. This takes a long time because I'm trying all the time to listen for possibilities beyond the actual sounds before me. I trim and level up the audio files, removing any unwanted sections, then open them up in Reaper, a digital audio workstation application which has a very simple time stretch function. This is where the sounds are timestretched, lengthened more often than shortened, a procedure which reveals new morphologies and further potential. At the same time I apply equalisation or filtering, which reduces or boosts frequencies, reduction being by far the most common procedure. I use a digital equaliser called Equilibrium made by DMG Audio which was recommended by a professional sound engineer. It offers digital emulations of all the great hardware equalisers and the level of detail and control it affords is unparalleled.
Where does this leave me? Well, from there I build up layers of sound in Wavelab's montage feature, which allows me to stack layers simultaneously, modify volume levels in great detail and process them further if required. This is where a composition comes alive, or dies a slow death. If I've learned anything over the years it's that there's no point in spending four or more hours a day working intensively with audio at fairly high volume and in great detail. The ears become fatigued and musical judgement diminishes. This doesn't mean that you can't work on the piece, it's just that you spend more time thinking about the composition in the abstract, away from the actual sounds, a challenging but interesting process in itself but one which can lead to better decisions own the long run.
With this most recent composition I made two big mistakes, along with all the numerous little ones. First I began working with sounds identical to or very similar to sounds that I'd used before. This undermines an approach to music, a core of my practice, which requires a fresh investigation with each new work. Why it took me so long to realise the mistake is beyond me. Another mistake, which I identified as it happened and which led to a resolution of all the major problems, was that I began trawling through my archives looking for 'something else' or something 'more suitable'. That's when the penny dropped and from there I returned to some of the less prominent sounds in my original work. The principal sounds here were of a joiner fitting out the inside of a nearby shop (which acted as a resonant cavity) taken on the street opposite the Abbey walls which reflected and dispersed the sounds around the built environment.
Sometimes we do actually learn from our mistakes but not as fast or as well as we'd like.
