Detailed Description

Plugin module that create media nodes that perform gain control on PCM audio data.

These media nodes expect media packets with PCM audio as input, and produce media packets with PCM audio as output. They amplify or attenuate the PCM audio by a variable gain factor. These media nodes listen for ReplayGain values set by other nodes in the chain when they are found in certain media format or meta-data.
