Implementation of the EBU R128 loudness standard.

The European Broadcasting Union Loudness Recommendation (EBU R128) informs broadcasters how they can analyze and normalize audio so that each piece of audio sounds roughly the same volume to the human ear.

This crate provides an API which analyzes audio and outputs perceived loudness. The results can then be used to normalize volume during playback.


  • Implements M, S and I modes
  • Implements loudness range measurement (EBU - TECH 3342)
  • True peak scanning
  • Supports all samplerates by recalculation of the filter coefficients

This crate is based on the libebur128 C library.
