Package com.tagtraum.audiokern.replaygain

Class ReplayGainAlgorithm

java.lang.Object

com.tagtraum.audiokern.replaygain.LoudnessNormalization

com.tagtraum.audiokern.replaygain.ReplayGainAlgorithm

public class ReplayGainAlgorithm
extends LoudnessNormalization

ReplayGain algorithm.

Contrary to the original proposal, this implementation uses a reference level of 89dB SPL. This in accordance with everyone else.
