[sc-users] re: bizarre audio dropouts
Title: re: bizarre audio dropouts
i'm sorry but i'm still unclear, actually it's prob'ly just my
vocabulary. the cutoff freq value is fixed at 1700 hz. the
input signal may vary wildly from one sample to the next due to being
put through a Pan2 using the functions for x which go from -1 to 1(see
below). the mul is following the same function x but transposed
to 0 - 1.
the spatialization functions in use are chosen from the following
array each time a spawn starts:
x = [XLine.kr(1.0.rand, 1.0.rand, dur, [1,
-1].choose),
Line.kr(1.0.rand2, 1.0.rand2, dur, [1,
-1].choose),
Plug.kr(Dust.kr(10.0.rand, [1, -1].choose)),
SinOsc.kr(10.0.rand, pi.rand, EnvGen.kr(xEnv.at(xLoc))),
LFNoise0.kr(10.0.rand,
EnvGen.kr(xEnv.at(xLoc))),
LFNoise2.kr(10.0.rand,
EnvGen.kr(xEnv.at(xLoc))),
Saw.ar(10.0.rand,
EnvGen.kr(xEnv.at(xLoc)))];
i tried running the control LFO's at 1.0.rand instead of
10.0.rand but it still dogs out. the Array of 8 stereo
spawns is mixed down to stereo, and the output of that is what
this is the current code in use at the end of the spawn (there is
an array of 8 spawns)
p = PlayBuf.ar(voice, 44100, speed);
e = EnvGen.ar(
env2, Pan2.ar(p, min(1, x), 0.5 ));
lpf1 = EnvGen.ar(env3,
LPF.ar(e.at(0), 1700,
Lag.kr(lFunc)));
lpf2 = EnvGen.ar(env3,
LPF.ar(e.at(1), 1700,
Lag.kr(rFunc)));
lpf = [lpf1, lpf2];
e+ lpf //output of spawn(s)
i think i'll just put the LPF on the output of the stereo mix and
call it good enough for now, but it's perplexing how to
implement
thanks bob
I mean discontinuities in the signal going into the cutoff
frequency
control of the filter.
A discontinuity means a jump to a widely different sample value
from
the previous sample.

by discontinuities do you mean
changes in the audio signal, freq or
the mul? the mul is changing radically, but not the freq.
is there a
simpler way to write this?
