// Streaming a File in From Disk
// In some cases, for instance when working with very large files, you might not want to load a sound completely into memory. Instead, you can stream it in from disk a bit at a time, using the UGen DiskIn, and Buffer's 'cueSoundFile' method:
// (
// SynthDef("tutorial-Buffer-cue",{ arg out=0,bufnum;
// Out.ar(out,
// DiskIn.ar( 1, bufnum )
// )
// }).send(s);
// )
// b = Buffer.cueSoundFile(s,"sounds/a11wlk01-44_1.aiff", 0, 1);
// y = Synth.new("tutorial-Buffer-cue", [\bufnum,b.bufnum], s);
// b.free; y.free;
// This is not as flexible as PlayBuf (no rate control), but can save memory.
