Re: [linux-audio-user] stretching sound

Hi all! I've been trying to stretch a soundfile. It is a piano track with mostly two voices only. I did it with an fft plain phase vocoder. Now there are a lot of parameters and I got some undesireable delay. In general the stretched sound was good, but the delay is disturbing. So here's the question, how should I set the following parameters to get the best result? fft-length (as high as possible?), windows per second, window length, windowtype (hamming, triangular, kasier with several coeffecients). Any ideas or practical experience with that? - I'm NOT doing it in realtime, so CPU-time is no problem. I've got time! :-)
