	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,

	best -august.

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.
