In simple English
Kira is a set of building blocks for game creators who want rich audio. It lets you fade sounds in and out, apply filters that muffle noise, and keep background music on strict musical beats. You need to write code in the Rust programming language to use it. It is free to use in your own projects under an open-source licence. You will spend time writing code to hook it into your game engine.
What it is
Kira is a library written in Rust for expressive game audio. It provides audio mixing, time clocks, spatial sound, and smooth property changes.
What it is good for
Game developers using the Rust programming language who need precise control over music timing and sound effects without relying on a bulky game engine audio system.
- Changes audio properties smoothly over time with tweens.
- Aligns sound events to an internal clock for musical timing.
- Applies effects like filters to specific audio tracks.
- Requires writing code in Rust.
- Mainly built for desktop computers, with limited support in web browsers.
- Does not include a graphical sound editor.

- RustAudio/rodio2.5k stars
Another audio library for Rust focused on simple playback rather than expressive mixing.
- spotify/pedalboard6.4k stars
Applies audio effects to recordings from Python, including studio plug-ins, without calling another program.
- iver56/audiomentations2.3k stars
Spoils sound recordings on purpose, 39 ways, so a model trained on them copes with real rooms.
- shaka-project/shaka-packager2.6k stars
Cuts a video file into the pieces and index files that a browser needs in order to stream it.
