I'm trying to achieve DRC with surround51, I have the DRC configuration that is in many webs/forums:
pcm.ladcomp {
type plug
slave.pcm "ladcomp_compressor";
}
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:0,0";
path "/usr/lib/ladspa";
plugins [{
label fastLookaheadLimiter
input {
#InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release time (s) 0.01 -> 2
controls [ 14 -15 0.8 ]
}
}]
}
If I do a speaker-test -c 6 -D ladcomp -t wav I only hear front-left and front-right
Could anyone guide me on how to do this?, is this actually possible?
I have tried things like slave.pcm surround51 in fastLookaheadLimiter, and many combinations, but I always end up with errors like the device is no usable.
Thank you in advance.
Carlos.
