Example

extern crate portaudio_rs as portaudio;

fn demo() -> portaudio::PaResult
{
    let stream = try!(portaudio::stream::Stream::open_default(
                          0, // input channels
                          1, // output channels
                          44100.0, // sample rate
                          portaudio::stream::FRAMES_PER_BUFFER_UNSPECIFIED,
                          None // no callback
                     ));

    try!(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; }
    }

    try!(stream.write(&buffer));

    Ok(())
}
