TRADITIONAL (?) IMPLEMENTATIONS OF A PHASE-VOCODER: THE TRICKS OF THE TRADE
@inproceedings{Gtzen2000TRADITIONALI, title={TRADITIONAL (?) IMPLEMENTATIONS OF A PHASE-VOCODER: THE TRICKS OF THE TRADE}, author={Amalia de G{\"o}tzen and Nicola Bernardini and Daniel Arfib}, year={2000} }
Although the use of the phase-vocoder is not a very recent technique in musical applications and an extensive literature exists on the subject (cf.[1, 2, 3, 4, 5, 6, 7, 8] ), hardly any fairly complete reference implementation can be found (cf. for example[9] pp.256-258, where the resynthesis part is performed through an oscillator bank instead of an iFFT). This paper describes in depth an implementation of a phasevocoder which was entirely coded in MATLABTM to be added to the COST-G6—DAfx web…
