Hi list,
In a installation I'm building, I use veejay (veejayhq.net) for video display, and route the audio of the video for further mixing in pd. This works very well.
Under some circumstances, I change the video playback speed. Veejay has a feature called "trickplay" that adjusts the audio to the video length by changing the pitch much like a 33rpm vynil record played at 45rpm.
What I want is keep the original pitch of the sound. So I figured out timestretching is what to do. I can send the speed factor of the video to pd. So I tried the timestretch~ external, the vocoder example (got this advice from list archive). They both sound terrible, even with the audio files from the examples (bell.aiff).
So is it something doable in real-time or do I have to look for a workaround ? Any advice is welcome.
