Gentlemen,
On CLM-3 and SND I get the actual duration of a sound (number of
samples) by assigning the 'end' variable the following operation:
(end (* dur *srate*)
where dur is a defined parameter on definstrument or define* (scheme).
How can I handle the same expression on snd-rt, since AFAIK in
real-time, the duration parameter is arbitrary.
Just in case there is a misunderstanding: Snd-rt has a scheduler, so the
length of the instrument can be set.
(<rt-out> :dur 1 3
(oscil))
is the same as:
(definstrument os (start dur)
(let ((o (make-oscil)))
(run
(loop for i from (* *srate* start)
to (+ (* *srate* start)
(* *srate* dur))
do (let ((val (oscil o)))
(outa i val)
(outb i val))))))
(with-sound () (os 1 3))
Do I average or is there
like a system handling mechanism which takes care of this issue?.
The reason for this question is that in the case of delay-lines, lengths
are pretty much function of durations and sampling-rate.
I guess that depends on the situation...
