Certain audio APIs offer a number of parameters that influence the
I/O latency of a stream. By default, RtAudio will attempt to set
these parameters internally for robust (glitch-free) performance

By passing the RTAUDIO_MINIMIZE_LATENCY flag to the openStream()
function, internal stream settings will be influenced in an attempt

To continue normal stream operation, the RtAudioCallback function
should return a value of zero. To stop the stream and drain the
output buffer, the function should return a value of one. To abort
