# Real-World Pass-Thru Device Examples

Using a Loopback virtual audio device as a pass-thru enables even more audio control. Below, we've listed a few examples to help you get started.

#### Route Audio Between Any Applications

Set your pass-thru device as the audio output in one application and the audio input in another to make audio flow between applications. For example, set a pass-thru device as the output at the end of an Audio Hijack chain, and the input in Skype. Now, audio will flow from your Audio Hijack session to the other caller in Skype!

#### Live Stream a Podcast

As a podcast is being recorded, the “Podcast Pass-Thru” device pictured below is making it easy to simultaneously live stream that audio to listeners on the Internet:

Audio Hijack Passing Audio to the “Podcast Pass-Thru” Device

This example uses Audio Hijack to capture audio from several sources: a microphone for local audio input, Skype for remote audio input, and iTunes for background music. In addition to being recorded, that audio is all sent to an Output block, where the “Podcast Pass-Thru” device has been selected.

Nicecast Broadcasting the “Podcast Pass-Thru” Device

To provide a live web stream for listeners, Nicecast is used. Above, the “Podcast Pass-Thru” device has been selected as an audio input in Nicecast's Source drawer. Now all the audio that's being played into “Podcast Pass-Thru” will be heard via the broadcast.

#### Use Multiple Pass-Thru Devices for Even More Power

If you utilize multiple pass-thru devices at once, you'll have even more power in routing your audio, particularly when teaming them up with Audio Hijack. For instance, you can use multiple pass-thru devices and Audio Hijack, along with FaceTime and Skype, to host a three person podcast with signal processing. The possibilities are nearly infinite!
