ReplayGain

streaming mode | Loudness/dynamics category

Inputs

  • signal (real) - the input signal

Outputs

  • replayGain (real) - the ReplayGain gain value in dB

Parameters

  • applyEqloud (bool ∈ {true, false}, default = true) :
    enables whether this algorithm should apply an equal-loudness filter (set to false if the input audio signal is already equal-loudness filtered)
  • sampleRate (real ∈ (0, ∞), default = 44100) :
    the sampling rate of the audio signal [Hz]

Description

This algorithm computes the Replay Gain loudness value of an audio signal. The algorithm is described in detail at [1]. The value returned is the 'standard' ReplayGain value, not the value with 6dB preamplification as it is computed by lame, mp3gain, vorbisgain, and all widely used ReplayGain programs.

This algorithm is only defined for input signals which size is larger than 0.05ms, otherwise an exception will be thrown.
