[chuck-users] chuck-users Digest, Vol 56, Issue 18

[Michael Hammond]

Thanks all for your responses.  Just to clarify, my hope is to make a
standalone app that can randomly select among 20-30 sound files to play back
5-8 simultaneously as a single "track."  The hope then is that users can
move to different points in the playback of the "track" just as they would
in an MP3 player like itunes.  I like the command-line idea, but it seems
like jumping to different parts of the audio files might not be possible.
 Is that true?

Perry, I'll look into the chunks idea when I get home.  I like it because it
would allow me to keep everything in ChucK.  My only concern is that pausing
playback to periodically load new chunks into the buffer would result in
stutters.  Does anyone have any experience with this?

Thanks!

Michael
