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

phase += 0.03;
if phase > 1.0 { phase -= 2.0; }
