Audio Output Using LabVIEW's "Play Waveform" Express VI

Module by: Ed Doering

Summary: Learn how to play an audio signal (1-D array) using your computer's soundcard.

Overview

A 1-D array representing an audio signal can be played directly by the computer’s soundcard using the Play Waveform Express VI. The screencast video shows how to listen to an audio signal source (a sinusoid in this example). The 1-D array must first be converted to the waveform data type using the Build Waveform node.
