PortAudio Tutorial

Initializing PortAudio

Before making any other calls to PortAudio, you must call Pa_Initialize(). This will trigger a scan of available devices which can be queried later. Like most PA functions, it will return a result of type paError. If the result is not paNoError, then an error has occurred.

err = Pa_Initialize();
if( err != paNoError ) goto error;

You can get a text message that explains the error message by passing it to

printf(  "PortAudio error: %s\n", Pa_GetErrorText( err ) );
