Digital Audio Effects, talk 7: Time-frequency processing

In these DAFx talks, the main concepts in the field of audio effects processing will be presented. In this seminar, we will initially present some basic concepts for time-frequency processing and some implementation models (filter-bank, FFT analysis, IFFT and sine sum resynthesis and gaboret sum). Next, we will see some audio effects that can be produced as filtering, dispersion, time-stretching, pitch-shifting, stable/transient component separation, mutation of sounds, robotization, whisperization, denoising and spectral panning.
