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,

> 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?
