Many apps may want to use paFramesPerBufferUnspecified, which tells PortAudio to pick the best, possibly changing, buffer size.*/ patestCallback, /* this is your callback function */ &paData ); /*This is a pointer that will be passed to your callback*/ An example of a good callback function would be very useful, but of course any help is appreciated,
PortAudio: Writing a Callback Function
http://www.portaudio.com/docs/v19-doxydocs/writing_a_callback.html
Here is an example callback function from the test file "patests/patest_saw.c". It calculates a simple left and right sawtooth signal and writes it to the output buffer. Notice that in this example, the signals are of float data type. The signals must be between -1.0 and +1.0.
