https://stackoverflow.com/questions/65806332/output-in-portaudio
In a stereo PCM stream the left channel are the even samples (0,2,4) and the right channel are the odd samples (1,3,5). Frequency and amplitude are characteristics of the waveform, not parameters passed as variables. In the example frequency is determined by the size of the steps (left_phase += 0.01 and right_phase += 0.03). Amplitude is determined by the …

PortAudio: Blocking Read/Write Functions
http://portaudio.com/docs/v19-doxydocs/blocking_read_write.html
The example below, excepted from patest_read_write_wire.c, shows how to open the default device, and pass data from its input to its output for a set period of time. Note that we use the default high latency values to help avoid underruns since we are usually reading and writing audio data from a relatively low priority thread, and there is usually extra buffering required to make …
