I guess I can split the six channels in three limiters using the multi plugin, but how I can join them back? In the ladspa are other limiters, but they do not have the gain control so they do not actually increase the volume. Just adding plain 20db of amplification distorts the sound... Maybe

I probably don't know any answers, but would like to make sure I at least understand the question. Are you trying do AGC on a pair-wise basis? Or, is it something else you're trying to do? Thanks, Robert Riches Date: Sun, 13 Oct 2013 15:02:42 +0200 From: Paolo Bolzoni

Sorry, I am not much in this stuff... But I am reading now that AGC is Automatic gain control and it seems what I would like to do. I am trying to have a more or less constant volume of the speaker output. The configuration I posted in the first email works in this sense for stereo; it does not

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

the problem with the configuration, I think, is: the plugins can handle a maximum of 2 channels. unfortunately, I cannot tell you exactly how, but it *should* be possible to route 3 pairs of channels to separate instances of the plugins. such a setup might also make sense musically. it might be
