They can differ in the sample rates -supported, bit widths, etc. PortAudio provides a simple way to query for -the available devices, and then pass the selected device to Pa_OpenStream(). -For an example, see the file "pa_tests/pa_devs.c". -<p>To determine the number of devices: -<blockquote> -<pre>numDevices = Pa_CountDevices();</pre> -</blockquote> -You can then query each device in turn by calling Pa_GetDeviceInfo() with -an index. -<blockquote> -<pre>for( i=0; i<numDevices; i++ ) { - pdi = Pa_GetDeviceInfo( i );</pre> -</blockquote> -It will return a pointer to a <tt>PaDeviceInfo</tt> structure which is -defined as: -<blockquote> -<pre>typedef struct{ - int structVersion; - const char *name; - int maxInputChannels; - int maxOutputChannels; -/* Number of discrete rates, or -1 if range supported. */ - int numSampleRates; -/* Array of supported sample rates, or {min,max} if range supported. */ - const double *sampleRates; - PaSampleFormat nativeSampleFormat; -}PaDeviceInfo;</pre> -</blockquote> -If the device supports a continuous range of sample rates, then numSampleRates -will equal -1, and the sampleRates array will have two values, the minimum -and maximum rate. -<p>The device information is allocated by Pa_Initialize() and freed by -Pa_Terminate() so you do not have to free() the structure returned by Pa_GetDeviceInfo().</blockquote> -<font size=+2><a href="http://www.portaudio.com/">home</a> | -<a href="pa_tutorial.html">contents</a> -| <a href="pa_tut_util.html">previous</a> | <a href="pa_tut_rw.html">next</a></font> -</body> -</html> |
