BufRateScale buffer rate scaling in respect to server samplerate
superclass: BufInfoUGenBase
returns a ratio by which the playback of a soundfile is to be scaled
*kr(bufnum)
*ir(bufnum)
the .ir method is not the safest choice. Since a buffer can be reallocated at any time,
using .ir will not track the changes.
// example
s.sendMsg("/b_allocRead", 0, "sounds/a11wlk01.wav");
(
x = { arg rate=1;
BufRd.ar(1, 0, Phasor.ar(0, BufRateScale.kr(0) * rate, 0, BufFrames.kr(0)))
}.play;
)
