Lenses

A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual Connexions member, a community, or a respected organization.

Real-Time Audio Output in LabVIEW

Module by: Ed Doering

Summary: Learn how to set up the framework for your own LabVIEW application that can generate continuous audio output and respond to 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")
