Hi, please also check the generic LADSPA plugin support of liquidsoap You can use any existing LADSPA plugin.
For our radio we wrote the rms_leveler LADSPA plugin for mastering. This is a look-ahead automatic gain control based on a target RMS level. This plugin will always generate the same loudness of -20dB FS, which allows to have some dynamic range. Loud parts will be turned down, quiet parts will be turned up. As a result there low additional compression or change of EQ, since most sources much higher loudness. This helps on using different audio sources with different loudness levels. Depending on the size of the lookahead window there will be some delay in the processing chain. For ubuntu there is a package rms-leveler at https://launchpad.net/%7Emc-1/+archive/ubuntu/audio-tools There are 3 versions available each having a different window radio = ladspa.rms_leveler_3s(radio) radio = ladspa.rms_leveler_6s(radio) radio = ladspa.rms_leveler_10s(radio) Additionally the package contains 3 limiters rms_limiter_3s, rms_limiter_6s and rms_limiter_10s which only limit the audio to target RMS of -20dBFS but do no upward amplification. Please see also EBU-R128 which contains some helpful hints how to do process audio in radio.
