ALSA allows you to use LADSPA plugins in a software plug layer.

check out

I've got a system I'm doing tech support on, and I'm trying to get allaudio streams normalized/compressed before the audio is spit out thespeakers.Basically, we've got several buttons that play an audio stream through
mpg123.  The streams are different volumes and that understandablyupsets the customers when they change audio streams and it's suddenlyblaring christian contemporary music at their patrons.Does anyone know of any way to do this, or at least any little
compression/normalization apps I might be able to pipe the datathrough? I would prefer to avoid JACK, but that's only because I don'twant to have to do more work than necessary, and this isn't (rather,
shouldn't be) a very complex system.Any input would be appreciated.  Thanks.-NathanPS: This godawful thing is running on FC4 (vanilla, for all intentsand purposes), btw._______________________________________________
