I’ve been investigating IRCAM’s Audiosculpt sound analysing and transforming software. been using it to extract partial overtones from guitar recordings from the Big Toe project. it has amazingly smooth time-stretching when taken to extremes. i’ve been reading some theory behind FFT in order to make the most of the analysis parameters – to cut a long story short; long window sizes give you accurate frequency information but inaccurate time-based info. and vice versa. somebody or others uncertainty principle. also been doing sonogram analysis of some of my favorite artists work which has been very revealing.
reading through curtis roads microsound this evening to get some background theory for granular synthesis.
