PortAudio bindings for Rust
Example
fn demo() -> rportaudio::rpa_error::PaResult {
let stream = rportaudio::stream::Stream::open_default(
0, // input channels
1, // output channels
44100.0, // sample rate
rportaudio::stream::FRAMES_PER_BUFFER_UNSPECIFIED,
None, // no callback
)?;
stream.start()?;
let mut phase = 0.0f32;
let mut buffer = Vec::with_capacity(44100);
for _i in (0..44100) {
// Small amplitude such that the test does not produce sound
buffer.push(phase * 0.001);
phase += 0.03;
if phase > 1.0 { phase -= 2.0; }
}
stream.write(&buffer)?;
Ok(())
}
