Audio Hijack

Audio Hijack is best used with loopback but can be used as a standalone program as well. Like Loopback it was developed by Rogue Amoeba and is based around capturing audio internally. One useful function of Audio Hijack is that it can be used to refine and effect audio streams using its built-in library of effects and then send them out to whatever program you want (or if using loopback to a virtual device). Audio Hijack is particularly useful for podcasters as well as anyone who wants to record audio with some customization but doesn’t have the time to tackle larger programs. New to version 3.7 Audio Hijack allows streaming directly to RTMP servers making it a good option for streaming audio-only performances.

Loopback

Loopback is an audio routing and mixing utility available for MacOS created by Rogue Amoeba.  Loopback allows you to create a virtual input device, assign sources (such as a physical microphone, audio from chrome, etc), route it as many channels as needed, and then add monitors (headphones, speakers) if needed.  Loopback is a great way of getting audio from one program on your computer to another (such as inputting Qlab to zoom). Anywhere where you can configure a microphone input or speaker output can be set to go to a virtual loopback device.  It pairs particularly well with audio hijack.

NDI Tools

NDI Tools are a suite of tools made by Newtek for sharing video and audio across networks using the NDI protocol. While it is usually geared towards running on local networks as of version 5 it is possible to share video sources across the internet using NDI Bridge. NDI has direct compatibility with most modern video programs and has plugins for the Adobe Creative Cloud.

While NDI can be fairly CPU heavy to encode and decode, it can open up a whole host of possibilities for sharing video across various machines.  There are apps available to share smartphone cameras and screens as NDI sources and the tools package contains the NDI webcam utility which creates a virtual webcam (for zoom, etc) using any NDI feed on the network.

The full set of tools is Windows only but the MacOS tools still offer a lot of functionality.

COST:

  • NDI Tools are free

  • Some apps are paid

  • Specific hardware is also available
