Description::
|
||
|
|
|
||
|
|
Returns the current number of allocated samples. A sample is not the same as a frame (compare with link::Classes/BufFrames:: ); a frame includes the samples in each channel of the buffer. Only for a mono buffer are samples the same as frames.
|
||
|
|
code::
|
||
|
|
samples = frames * numChannels

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