soloud-rs

A crossplatform Rust bindings for the soloud audio engine library.

Supported formats: wav, mp3, ogg, flac. The library also comes with a speech synthesizer.

• The official soloud website
• The official soloud repo

Usage

toml [dependencies] soloud = "1"

Or to use the git repo: toml [dependencies] soloud = { git = "https://github.com/moalyousef/soloud-rs" }

To play audio: ```rust,no_run use soloud::*;

fn main() -> Result<(), Box> { let mut sl = Soloud::default()?;

let mut wav = audio::Wav::default();

wav.load(&std::path::Path::new("sample.wav"))?;

sl.play(&wav); // calls to play are non-blocking, so we put the thread to sleep
while sl.voice_count() > 0 {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

wav.load(&std::path::Path::new("Recording.mp3"))?;

sl.play(&wav);
while sl.voice_count() > 0 {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

Ok(())

} ```

To play speech: ```rust,no_run use soloud::*;

fn main() -> Result<(), Box> { let mut sl = Soloud::default()?;

let mut speech = audio::Speech::default();

speech.set_text("Hello World")?;

sl.play(&speech);
while sl.active_voice_count() > 0 {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

speech.set_text("1 2 3")?;

sl.play(&speech);
while sl.active_voice_count() > 0 {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

speech.set_text("Can you hear me?")?;

sl.play(&speech);
while sl.active_voice_count() > 0 {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

Ok(())

} ```

To add a filter: ```rust,no_run use soloud::*;

fn main() -> Result<(), Box> { let mut sl = Soloud::default()?;

let mut wav = audio::Wav::default();
let mut filt = filter::EchoFilter::default();
filt.set_params(0.2)?; // sets the delay

wav.load(&std::path::Path::new("sample.wav"))?;
wav.set_filter(0, Some(&filt));

sl.play(&wav);
while sl.voice_count() > 0 {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

Ok(())

} ```

The examples can be found in the soloud/examples directory. They can be run using: bash cargo run --example simple cargo run --example speech cargo run --example filter cargo run --example load_mem You will need to have valid "sample.wav" and "Recording.mp3" audio files in the project root. Or you can change the paths to point to any supported audio file.

There is also a demo gui application (using fltk) here.

Dependencies

A Rust compiler, C++ compiler, Cargo, CMake and git (all these need to be in your PATH). Ninja is recommended, but not required, and will be used if found. This crate uses the miniaudio backend by default which assumes default sound drivers are functional.

Backends

The default backend is miniaudio, however Soloud supports several backends to varying degrees. To enable support of a certain backend, alsa for example: toml [dependencies] soloud = { version = "1", default-features = false, features = ["alsa"] } This also assumes that those libraries headers are in your include path where CMake can find them, otherwise you can set it via the command line (posix): bash export CXXFLAGS="-I /path/to/include" or for Windows: bash set CXXFLAGS="-I C:\\path\\to\\include" The same can be done for CFLAGS if needed.

Supported backends:

• miniaudio
• oss
• alsa
• sdl2
• sdl2-static
• portaudio
• openal
• xaudio2
• winmm
• wasapi
• opensles
• coreaudio
• jack

Android support

The ANDROIDSDKROOT and ANDROIDNDKROOT need to be set.
