This video was taken at a two-day conference, entitled Ghost in the Machine, hosted by IPLAI and ICASP, at McGill University, on 2 Feb., 2011.
I had been working on a t-stick sound vocabulary that integrates well with winds – wood wind instruments to be more precise – capturing not only sustained 'wind' sounds but also a wealth of extended technique sounds (e.g., key clicks, tongue rams, flutter, air noise, etc.). For these extended technique sounds, I initially experimented with audio files – recordings of techniques played by actual wind instruments. I was not happy with the result seeing how sampled audio can lead to a very static aural experience especially when the samples are treated with very little processing, colouring, effects, etc. I find it more interesting to listen to, say, tongue ram sounds on an actual clarinet rather than replicating a single 'ram' sound over and over again. My solution was to implement several physical models – my usual approach – that emulate or evoke extended techniques on wind instruments. This allows me the added bonus of being able to evoke an extended technique sound (when played with one particular gesture) and then to alter the sound quite dramatically (with another gesture).
