BufSamples

Current number of samples in buffer.

Description

Returns the current number of allocated samples. A sample is not the same as a frame (compare with BufFrames ); a frame includes the samples in each channel of the buffer. Only for a mono buffer are samples the same as frames.

samples = frames * numChannels

Class Methods

*kr (bufnum)

From superclass: BufInfoUGenBase

*ir (bufnum)

From superclass: BufInfoUGenBase

Arguments:

bufnum

Buffer index.

Discussion:

WARNING: The .ir method is not the safest choice. Since a buffer can be reallocated at any time, using .ir will not track the changes.

Examples

// example; this buffer is mono, so the number of samples matches the number of frames
b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");

// indexing with a phasor
{ BufRd.ar(1, b, Phasor.ar(0, BufRateScale.kr(b), 0, BufSamples.kr(b))) }.play;

// indexing by hand
{ BufRd.ar(1, b, K2A.ar(MouseX.kr(0, BufSamples.kr(b)))) }.play;

b.free;
