Loudness Addict

Measure integrated loudness in LUFS and RMS standards.

Motivation

This project aims to deepen my Rust language skills combined with my interest in audio engineering.

Features

Example Output

> cargo run -- testsamples/beat.wav testsamples/sine.wav
    Compiling loudness-addict v0.1.0 (F:\Dev\loudness-addict)
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.65s
    Running `target\debug\loudness-addict.exe testsamples/beat.wav testsamples/sine.wav`
Loudness Addict 0.1.0

Parameters
["target\\debug\\loudness-addict.exe", "testsamples/beat.wav", "testsamples/sine.wav"]

testsamples/beat.wav Int. RMS: -9.18
testsamples/sine.wav Int. RMS: -15.05

Technical Requirements

Developed using Rust v1.82.0.

How to Use

Run with Rust and Cargo

First, you need to have Rust installed on your computer.

Open a terminal:

• Windows: run Windows Terminal, cmd, or PowerShell.
• Mac: run Terminal.
• Linux: run Terminal.

In the project root folder, run:

cargo run -- testsamples/beat.wav testsamples/sine.wav

Research

Rust Crates

• bs1770 - Loudness analysis conforming to ITU-R BS.1770-4
• hound - A wav encoding and decoding library

Standards

• Recommendation ITU-R BS.1770-5 (11/2023) BS Series: Broadcasting service (sound) Algorithms to measure audio programme loudness and true-peak audio level
• Loudness Metering: ‘EBU MODE’ Metering To Supplement EBU R 128 LOUDNESS NORMALIZATION

License

• The binary program uses MIT license.
• The crates use Apache 2.0 licenses.
