Python library for Audio Loudness measurements. Yet another implementation of ITU-R BS.1770, ITU-R BS.1771, EBU Tech 3341 and EBU Tech 3342.
This library provides a way to measure audio loudness and true peak measurements validated against the official EBU compliance test materials.
Its design focuses more on real-time processing, using a block-based approach suitable for audio engines, rather than offline processing of entire audio files.
- Historical tracking of all measurements over time
- Multi-channel audio support
- Compliance-based validation of measurements
- Integrated Loudness
- Short-Term Loudness
- Momentary Loudness
- Loudness Range (LRA)
- True Peak
This library is validated against comprehensive compliance test cases based on the official EBU and ITU-R documents:
- EBU Tech 3341
- Integrated, Momentary, Short-Term and True Peak measurements
- EBU Tech 3342
- Loudness Range (LRA) measurements
- ITU-R BS.2217
- Integrated Loudness measurements for various channel configurations
