@brief Self Testing Quality Assurance app for PortAudio
|
|
Try to open each device and run through all the
|
|
possible configurations. 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 outputs.
|

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