@section{note}
|
||
|
|
BufWr (in difference to link::Classes/BufRd:: ) does not do multichannel expansion, because input is an array. ::

Modulateable index into the buffer (has to be audio rate).

@section{Warning}
|

|
|
The phase argument only offers precision for addressing 2**24 samples (about 6.3 minutes at 44100Hz) ::
