i'm trying to introduce an effect subtly by fading it in (to avoid
clicks,
of course). i thought that it
would be easy to achieve this by using an xfade2 ugen and an
envelope. the
ugen would fade
between the original sound and the treated sound after the efx synth
has
been introduced. see
below.
for some reason, the effect is introduced, i get an audio click. but
when
it is released, there is no
click. any idea why this might be happening? i'm using an asr
envelope with
equal attack and decay
times to control the fade.
(
SynthDef.new("snd", { arg freq=2, width=1, mix= -1, in=0, out=0,
gate=1,
mute=0;
var snd, env, wet;
env = EnvGen.kr(Env.asr(0.15, 1, 0.15), gate, doneAction:2);
snd = SinOsc.ar(400, 0, 0.4 * env);
snd = Pan2.ar(snd, 0);
Out.ar(out, snd);
}).send(s);
SynthDef.new("effect", { arg freq=4, width=1, in=0, out=0, gate=1,
mute=0;
var snd, env, wet;
env = EnvGen.kr(Env.asr(0.15, 1, 0.15), gate, doneAction:2);
snd = In.ar(in, 2);
wet = snd * SinOsc.ar(freq, 0, width);
wet = XFade2.ar(snd, wet, (env*2) - 1); // xfade in & out
snd = Select.ar(mute, [wet, snd]);
ReplaceOut.ar(out, snd);
}).send(s);
)
// one at a time
x = Synth.new("snd");
y = Synth.tail(s, "effect"); // click
y.set(\gate, 0); // oh so smooth
