bs1770

ReplayGain 2.0 loudness normalizer based on the EBU R128/ITU BS.1770 standard (-18 LUFS, FLAC, Ogg, MP2, MP3, MP4, M4A, AAC, ALAC, Opus, ASF, WMA, WAV, AIFF, WavPack, APE)

A Rust library that implements ITU-R BS.1770-4 loudness measurement

Streaming, zero-allocation EBU R128 / BS.1770-4 loudness measurement in pure Rust. M, S, I, true peak, LRA — chunk-deterministic, no_std capable, EBU Tech 3341 14/14, no FFI.

Python library for Audio Loudness measurements

Open-source C++ audio-core library with BS.1770 / EBU Tech 3341 conformance tests, RT-safety primitives, and Barometer as a source-built JUCE reference plugin.

Open-source, headless C++20 audio-regression proof layer: the bpts CLI mints signed golden references from rendered WAVs and verifies candidate renders against them for CI, with a per-OS Barometer case study.

ASMR audio L/R balance scanner (ITU-R BS.1770-5, EBU R128, True Peak, 1/3-octave bands; high-rate friendly)

ITU-R BS.1770-4 / EBU R128 loudness meter in pure TypeScript — integrated LUFS, loudness range, true peak. Zero dependencies, streaming or one-shot, verified against libebur128 and the EBU conformance suite.

A loudness and true peak tool that runs in your browser and follows EBU R128 and ITU-R BS.1770. Compare files, check delivery targets, export results.

Offline loudness analysis for Windows and macOS — BS.1770/EBU Mode, ADM, reports, and privacy-first batch workflows.

Bit-exact BS.1770-4 Integrated LUFS, LRA, and True Peak for the browser, Web Workers, and Node. Zero deps. Pulled from luvlang.studio's mastering chain.

A complete C# port of libebur128, the EBU R128 loudness meter, for .NET 10. Zero managed allocation, Native AOT, unsafe internals. Verified against the original C built with MSVC: every stage bit-exact across eight configurations, throughput 0.92x to 1.03x. 139 tests.
