<p>PCM Interface is designed to write or read digital audio frames. A frame is the data unit converted into/from sound in one time unit (1/rate seconds), by example if you set your playback PCM rate to 44100 you'll hear 44100 frames per second. The size in bytes of a frame may be obtained from bits needed to store a sample and channels count.</p>
<p>See the <a class="el" href="pcm.html">PCM (digital audio) interface</a> page for more details. </p>
