Self Testing Quality Assurance app for PortAudio Try to open devices and run through all possible configurations. By default, open only the default devices. Command line options support opening every device, or all input devices, or all output devices. This test does not verify that the configuration works well. It just verifies that it does not crash. It requires a human to listen to the sine wave outputs. More...

Detailed Description

Self Testing Quality Assurance app for PortAudio Try to open devices and run through all possible configurations. By default, open only the default devices. Command line options support opening every device, or all input devices, or all output devices. This test does not verify that the configuration works well. It just verifies that it does not crash. It requires a human to listen to the sine wave outputs.

Pieter adapted to V19 API. Test now relies heavily on Pa_IsFormatSupported(). Uses same 'standard' sample rates as in test pa_devs.c.
