Description::

The Tap UGen allows a single tap at a delay into a buffer.

Tap uses the link::Classes/PlayBuf:: UGen internally

classmethods::
private:: categories

method::ar

argument::bufnum
The index of the buffer to use

argument::numChannels
Number of channels of the buffer

argument::delaytime
Tap delay; cannot be modulated

examples::
code::
// Create a buffer.
b = Buffer.alloc(s, s.sampleRate, 1); // enough space for one second of mono audio

// Write to the Buffer with BufWr, read using two Taps, one for each ear!
(
SynthDef(\helpTap, { |out, bufnum|
	var source, capture;

	source= SoundIn.ar(0); // use headphones to avoid feedback
	capture= BufWr.ar(source, bufnum, Phasor.ar(0,1, 0, BufFrames.ir(bufnum),1));

	Out.ar(out, Tap.ar(bufnum, 1, [0.1,0.9])); // multichannel expansion, so one tap each ear
}).add;
)

x = Synth(\helpTap, [\bufnum, b]);

x.free;
