LoudnessEBUR128Filter

streaming mode | Loudness/dynamics category

Inputs

  • signal (stereosample) - the input stereo audio signal

Outputs

  • signal (real) - the filtered signal (the sum of squared amplitudes of both channels filtered by ITU-R BS.1770 algorithm

Parameters

  • sampleRate (real ∈ (0, ∞), default = 44100) :

    the sampling rate of the audio signal [Hz]

Description

An auxilary signal preprocessing algorithm used within the LoudnessEBUR128 algorithm. It applies the pre-processing K-weighting filter and computes signal representation requiered by LoudnessEBUR128 in accordance with the EBU R128 recommendation.
