hello list, a colleague of mine seems to be extremely interested in performing exaggerated time stretching of audio files. i wrote a csound instrument based on the new streaming phase vocoding opcodes by richard dobson. adjusting window size, it can perform passable time stretching up to 6 or 8 times the duration of the original. but this colleague would like to have much more than that. he told me in in a visit to cologne he used a POD system, where he could stretch sounds up to 400 or 500 times... my questions are: - which linux applications can stretch sounds with good quality up to let's say at least 20 times? - is there anything like POD for linux? anyone knows how POD does the time-stretching? granular synthesis? thanks as always. lj --
