Dear list,
This is my .asoundrc, and the pair compressor + limiter works fine for
stereo input:
----------- >8
pcm.ladcomp_compressor {
type ladspa
slave.pcm "ladcomp_limiter";
path "/usr/lib/ladspa";
plugins [{
label dysonCompress
input {
#peak limit, release time, fast ratio, ratio
controls [0 1 0.5 0.99] }
}]
}
pcm.ladcomp_limiter {
type ladspa
slave.pcm "plughw:Audigy2";
path "/usr/lib/ladspa";
plugins [{
label fastLookaheadLimiter
input {
#InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release
time (s) 0.01 -> 2
controls [ 20 -1 0.8 ] }
}]
}
8< -----------
Unfortunately, it does not work for 6 channels.
I.e., this one works fine (I setup my system to use a certain PCM
via environment variable):
$ ALSAPCM='pcm.ladcomp_compressor' speaker-test -c 2 -t wav -l 5
This one does not and you hear only the left and right channels.
$ ALSAPCM='pcm.ladcomp_compressor' speaker-test -c 6 -t wav -l 5
Of course the hardware is wired correctly and this one works as expected:
$ ALSAPCM='pcm.surround51' speaker-test -c 6 -t wav -l 5
Since normally you have to select surround51 manually I thought that the
problem could be in the output pcm, and I rewrote like this. But it is the same:
----------- >8
#[...] analogous 51 compressor omitted
pcm.plug51 {
type plug
slave.pcm "surround51"
slave.channels 6
}
pcm.ladcomp_limiter51 {
type ladspa
slave.pcm "plug51"
path "/usr/lib/ladspa"
plugins [{
label fastLookaheadLimiter
input {
#InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release
time (s) 0.01 -> 2
controls [ 20 -1 0.8 ] }
}]
}
8< -----------
Is there a way? Any insight?
Yours faithfully,
Paolo
