how long is the long file? If it all fits in RAM, the process is pretty straightforward:
- load it in an array with
[soundfiler]
- read the array with two
[tabread~] objects and crossfade between them
If the file doesn't fit in RAM, then you'll need to use [readsf~] to read chunks of it. If you know in advance where in the file you'll start reading from, that's also kind of straightforward: prepare as many [readsf~] objects as there are possible start location, and send the [open( message to them. Whenever you need to start playing from a location, send a [1( message to the corresponding [readsf~] and crossfade it with the old one, to which you'll send a [0( and [open ( message as soon as the crossfade is completed, so that it becomes ready for the next play.
