Hey Guys I've had a vague Idea (which I find is often the best kind) for something to do with pure data. Basically, I want it to randomly select a clip from a long MP3 (just under an hour long) and play back, preferably with some speed manipulation. Although I'm not sure about how to do with with a large file in pure data. I suppose the trick might be to pull a minute or so whole-sale from the file and then manipulate the playback from an array. But really don't know where to start, with the possible exception of [readanySF~] to actually play a long file. any help? Cheers Andrew
Hi Andrew, I have not worked with mp3, but I've done something similar with susloop ~, may solve some, help is quite clear.
Best regards

Do you really have to use MP3? I think this might be easier to do with uncompressed WAV.

Andrew,
you should be able to use readanysf~ to do what you want.
just [open( the file and then [time_seek( or [pcm_seek( to any
position in the file and then [play(
you could also use soundfiler on a large wav file using -skip and and
-nframes to load the file. after that you can do normal table
lookup and manipulation (play forwards, backwards, slower, faster,
etc)
best -august.
