This IRCAM stuff is something similar than the FFT analysis from the last Buunshin video. Its all based on Fourier and the Sum of Sines. With different window settings its analysing the signal in every frequency band (not just 3 bands it can be hundreds or whatever) and re-synthetise it from sine waves. The window settings can be the key parameter for making it sounds realistic to the source or effected.
