<h2 id="details">Detailed Description</h2>
<p>The <a href="qabstractaudiodeviceinfo.html">QAbstractAudioDeviceInfo</a> class is a base class for audio backends.</p>
<p>This class implements the audio functionality for <a href="qaudiodeviceinfo.html">QAudioDeviceInfo</a>, i.e., <a href="qaudiodeviceinfo.html">QAudioDeviceInfo</a> keeps a <a href="qabstractaudiodeviceinfo.html">QAbstractAudioDeviceInfo</a> and routes function calls to it. For a description of the functionality that <a href="qabstractaudiodeviceinfo.html">QAbstractAudioDeviceInfo</a> implements, you can read the class and functions documentation of <a href="qaudiodeviceinfo.html">QAudioDeviceInfo</a>.</p>
