Mixer
Voices, buses, fades, loops and resampling for your audio callback. Rendering allocates nothing and takes no lock.
features = ["mixer"]Audio,
in your hands.
Decode, shape, measure, and encode.
One audio toolkit, written in safe Rust.
Nothing else to install.

Small API.
Useful things.
An immutable Audio holds your samples. Each operation returns a new one. Compose the steps you need, and keep the original.
Extract a clip, make it mono, resample to 16 kHz, and normalize its peak. The input stays untouched.
Read the getting-started guideuse audiobox::{AudioFormat, NormalizeOptions,
decode, encode};
fn prepare(bytes: &[u8]) -> audiobox::Result<Vec<u8>> {
let audio = decode(bytes)?;
let ready = audio
.cut(12.0, 30.0)?
.to_mono()
.resample(16_000)?
.normalize(NormalizeOptions::default())?;
encode(&ready, AudioFormat::Wav)
}Meet your
next format.
Bring files, encoded bytes, or planar PCM. The codecs are part of the crate, so the same Rust pipeline travels with your application.

¹ WAV writing supports PCM, float and G.711; no ADPCM encoder. MP3 encoding uses a simpler CBR model without VBR or psychoacoustic tuning. Read the release limitations.
Sound for your
game, built in.
Optional features add a real-time mixer, an 8-bit synthesizer that plays text scores, and sound effects drawn from a seed. Still no dependencies, and the same samples on every platform.
Synthesizer
Pulse, triangle, saw and noise channels playing music written as text, offline or chunk by chunk.
features = ["synth"]Sound effects
Jumps, coins, lasers and explosions from a few parameters, or from a preset and a seed.
features = ["sfx"]From the first sample
to your next project.
