Project: p5_sc / Examples: Buffer.read

Examples: Buffer.read

Reads a sound file from disk, and plays back the file once the read operation is completed. Frees the buffer upon a mouse click.

SynthDefs

SynthDef(\playbuf_2, { |bufnum = 0, outbus = 0, amp = 0.5, loop = 0, rate = 1.0|
	var data;
	data = PlayBuf.ar(2, bufnum, BufRateScale.kr(bufnum) * rate, 0, 0, loop);
	FreeSelfWhenDone.kr(data);
	Out.ar(outbus, data * amp);
}).store;
