# libloudness

A library that implements the ITU BS.1770 loudness algorithm and true peak recommendations for use with e.g. EBU R-128

Originally a c++ port of [libebur128](https://github.com/jiixyj/libebur128), with various optimizations and convenient extensions

## Features

- Written in c++20

- Supports [EBU R 128](https://tech.ebu.ch/docs/r/r128.pdf)

  - M, S and I modes ([EBU Tech 3341](https://tech.ebu.ch/docs/tech/tech3341.pdf)

  - Loudness range measurements ([EBU Tech 3342](https://tech.ebu.ch/docs/tech/tech3342.pdf))

  - True peak scanner

- Additional features based on ITU BS.1770

  - Median loudness calculation

  - Calculate global loudness without the relative gating

- Supports all realistic samplerates

- Supports both interleaved and non-interleaved input

- Limited optional multithreading support
