/** @file paqa_devs.c @brief Self Testing Quality Assurance app for PortAudio Try to open each device and run through all the possible configurations. @author Phil Burk http://www.softsynth.com Pieter adapted to V19 API. Test now relies heavily on Pa_IsFormatSupported(). Uses same 'standard' sample rates as in test pa_devs.c. */ /* * $Id: paqa_devs.c,v 1.1 2006/06/10 21:30:56 dmazzoni Exp $ * * This program uses the PortAudio Portable Audio Library. * For more information see: http://www.portaudio.com * Copyright (c) 1999-2000 Ross Bencina and Phil Burk * * Permission is hereby granted, free of charge, to any person obtaining * a copy of this software and associated documentation files * (the "Software"), to deal in the Software without restriction, * including without limitation the rights to use, copy, modify, merge, * publish, distribute, sublicense, and/or sell copies of the Software, * and to permit persons to whom the Software is furnished to do so, * subject to the following conditions: * * The above copyright notice and this permission notice shall be * included in all copies or substantial portions of the Software. * * Any person wishing to distribute modifications to the Software is * requested to send the modifications to the original developer so that * they can be incorporated into the canonical version. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF * CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION * WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. * */ #include #include #include "portaudio.h" #include "pa_trace.h" /****************************************** Definitions ***********/ #define MODE_INPUT (0) #define MODE_OUTPUT (1) typedef struct PaQaData { unsigned long framesLeft; int numChannels; int bytesPerSample; int mode; short sawPhase; PaSampleFormat format; } PaQaData; /****************************************** Prototypes ***********/ static void TestDevices( int mode ); static void TestFormats( int mode, PaDeviceIndex deviceID, double sampleRate, int numChannels ); static int TestAdvance( int mode, PaDeviceIndex deviceID, double sampleRate, int numChannels, PaSampleFormat format ); static int QaCallback( const void *inputBuffer, void *outputBuffer, unsigned long framesPerBuffer, const PaStreamCallbackTimeInfo* timeInfo, PaStreamCallbackFlags statusFlags, void *userData ); /****************************************** Globals ***********/ static int gNumPassed = 0; static int gNumFailed = 0; /****************************************** Macros ***********/ /* Print ERROR if it fails.
