Learn how to set up the framework for your own LabVIEW application that can generate continuous audio output and respondto changes on the front panel in real time.

Overview

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 Sound Output subVIs called Configure , Write , and Clear 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: lvt_audio_realtime-out.vi (right-click and choose "Save As")
