REVMIX -- play an input soundfile backwards
in RTcmix/insts/std
quick syntax:
REVMIX(outsk, insk, dur, AMP[, inputchan, PAN])
CAPITALIZED parameters are
pfield-enabled
for table or dynamic control (see the
maketable
or
makeconnection
scorefile commands). Parameters after the [bracket] are optional and
default to 0 unless otherwise noted.
p0 = output start time (seconds)
p1 = input start time (seconds)
p2 = input duration (seconds)
p3 = amplitude multiplier (relative multiplier of input signal)
p4 = input channel [optional; default is 0]
p5 = pan (0-1 stereo; 0.5 is middle) [optional; default is 0]
p3 (amplitude) and p5 (pan) can receive dynamic updates from a table or
real-time control source.

REVMIX plays a selected channel of
the input file backward for the specified duration, starting
at the input start time.
Usage Notes
If you specify a duration that would result
in an attempt to read before the start of the input file, REVMIX
will shorten the note to prevent this.
Note that you can't use this instrument with a real-time input
(microphone or aux bus), only with input from a sound file. (That's
because the input start time of an inst taking real-time input must
be zero, but this instrument reads backward from its inskip.) Duh...
The output of REVMIX may be mono or stereo
Sample Scores
very basic:
rtsetparams(44100, 2)
load("REVMIX")
rtinput("mysound.aif")
// do both channels of a stereo input file
REVMIX(outskip=0, inskip=5, dur=3, amp=1, inchan=0, loc=0.0)
REVMIX(outskip=0, inskip=5, dur=3, amp=1, inchan=1, loc=1.0)
