Python library for Audio Loudness measurements

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.

Purpose

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.

Features

• Historical tracking of all measurements over time

• Multi-channel audio support

• Compliance-based validation of measurements

Measurement Types

• Integrated Loudness

• Short-Term Loudness

• Momentary Loudness

• Loudness Range (LRA)

• True Peak

Compliance

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

Installation

Pip

$ pip install lupy

Dependencies

• numpy

• scipy
