Hi Jonty, oh and one more thing: There are some exellent algorithms outthere (e.g. the MPEX Time & Pitch Scaling Technology licensed from Prosoniq - which is unfortunately no free linux algo), some highly adapted to perform voice time stretching or other audio sources, some very complex (based on neuronal networks, ...) but you won't find any algorithm that doesn't produce any artifacts over a certain treshold of stretching.... :( Best regards Sebastian. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
