      <para id="id9058296">The interactive front panel is a hallmark of the LabVIEW programming paradigm. In this screencast video you will learn how to use the low-level <term>Sound Output</term> subVIs called <term>Configure</term>, <term>Write</term>, and <term>Clear</term> to build a general-purpose framework that can continually produce audio output, all the while responding to parameter changes on the front panel in real time. The example uses a sinusoidal source, but you can easily adapt the VI for your own signal sources; the finished VI from this example is available: <link src="lvt_audio_realtime-out.vi">lvt_audio_realtime-out.vi</link> (right-click and choose "Save As")</para>
