Sound library for games
Contents of this repository was moved to rg3d/rg3d-sound and development will be continued there.
rg3d-sound
Sound library for games and interactive applications written in Rust.
Key features
- Generic and Spatial sound sources.
- Built-in streaming for large sounds.
- Raw samples playback support.
- WAV format support (non-compressed).
- Vorbis/ogg support (using lewton).
- HRTF support for excellent positioning and binaural effects.
- Reberb effect.
Examples
Examples can be found in ./examples. Make sure you run examples with --release flag, debug version is very slow and may cause tearing of output sound.
Supported OS
- Windows (DirectSound)
- Linux (alsa)
How to build
Add rg3d-sound = "0.11.0" to your Cargo.toml. Supported Rust version is >= 1.38.
HRTF
Library has full HRTF support, it uses HRIR spheres generated using IRCAM HRIR database. HRIR spheres are produced using small tool written in C++ - hrir_sphere_builder. It is very important to find HRTF that suits you because they're very individual and overall perception fully defined by use of correct HRTF.
Contributions

- Overlap-add convolution - not used anymore due to significant distortions at segment boundary when impulse response changes.
- Overlap-save convolution - works much better when impulse response changes, there are only phase shift issues which are more less acceptable.
