🚀 Version 0.2.0 – First Complete Public Release
This is the first full-featured public release of PALA – Python Audio Loudness Analysis.
PALA is a modular Python package for measuring loudness and dynamics in audio files, based on the ITU-R BS.1770-5 standard. It includes LUFS (I/S/M), True Peak, RMS, DR and LRA, and is designed for use in mastering, research and audio toolchains.
✨ Features
- LUFS Integrated, Short-Term and Momentary (with gating and multichannel weighting)
- True Peak (oversampled), Sample Peak
- RMS (AES & ITU-R variants)
- DR (Dynamic Range), Crest Factor, Headroom
- Loudness Range (LRA, 10–95 percentile)
- Chunked processing for long files
- Modular structure with reusable components (
dynamics,lufs,utils,io) - CLI interface (basic single-file mode)
⚠️ Status
Alpha-quality release – results are consistent with most established tools (e.g. ffmpeg, pyloudnorm, APU plugins),
but not yet validated against ITU-R BS.2217 reference material.
Some deviations are expected, especially on edge cases.
