// 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.
