-Opening a Stream using Defaults

- -

The next step is to open a stream which is similar to opening -a file. You can specify whether you want audio input and/or output, how -many channels, the data format, sample rate, etc. There are two calls for -opening streams, Pa_OpenStream() and Pa_OpenDefaultStream(). -
Pa_OpenStream() takes extra parameters which give you -more control. You can normally just use Pa_OpenDefaultStream() -which just calls Pa_OpenStream() with some reasonable -default values. Let's open a stream for stereo output, using floating -point data, at 44100 Hz. -
-
err = Pa_OpenDefaultStream(
-    &stream,        /* passes back stream pointer */
-    0,              /* no input channels */
-    2,              /* stereo output */
-    paFloat32,      /* 32 bit floating point output */
-    44100,          /* sample rate */
-    256,            /* frames per buffer */
-    0,              /* number of buffers, if zero then use default minimum */
-    patestCallback, /* specify our custom callback */
-    &data );        /* pass our data through to callback */
-
-If you want to use 16 bit integer data, pass paInt16 instead of -paFloat32.
