Experiments trying to use Rust for audio programming.

Consider anything in this repository a draft.

⚠️ Goals
  • Goal 1: Learn & have fun
    • This is goal #1 and it's very important to keep it in mind if you end-up depending on one of the crates in this repository
  • Goal 2: Build tools for aiding development
  • Goal 3: Experiment with audio software GUI in Rust

🛠 Rust libraries and tooling

Workspace & Building

The project is set-up with a cargo workspace. Running cargo commands at the root directory should compile all crates sharing caches.

To build the whole project run:

git submodule update --init
cargo build

To run tests:

cargo test

On OSX you might want to run ./scripts/test.sh instead of that command.

Build outputs should be on target/debug or target/release.

Packaging apps and VSTs

Package VSTs using ./scripts/dev.sh build. This will build all the packages, build specific crates' outputs with ./scripts/dev.sh build <path>.

Looper, Metronome and other (flutter / macOS builds)

See instructions on their READMEs under crates/apps.

Building on linux

Since this is bringing in all the possible rust crates, you'll need to install quite a few dependencies.

See .github/workflows/default.yml for a list of what's needed on Ubuntu.


cargo clippy


Benchmarks using criterion will be slowly added. In order to run benchmarks use:

cargo bench

Profiling on macOS


cd ./crates/oscillator
cargo instruments -t time --bench sine_oscillator_benchmark -- --bench

Generating flamegraphs from benchmarks

NOTE I couldn't get this to work on macOS

Flamegraphs can be generated using cargo-flamegraph:

cargo install flamegraph

The tool can then be used to run a criterion benchmark and generate a flamegraph:

cargo flamegraph --bench sine_oscillator_benchmark -- --bench

Snapshot testing audio processors

See docs/monorepo-tooling/SNAPSHOT_TESTING.md.
