Audio Hijack is from the creators of Nicecast, Rogue Amoeba. Now in its 4th edition, it's a beautifully simplistic DAW (Digital Audio Workspace) that's designed to make broadcasting, recording, and mixing shows easier than ever on Macs.

How Audio Hijack Works

Audio Hijack uses blocks that you can drag and drop within the app. The blocks let you capture, record, and manipulate audio, as well as mix it together and send it to various places.

For example, you can send audio from your browser by dragging in the "Application" block and connecting it to your browser of choice, e.g. Google Chrome.

Once you've added your audio sources, the new mixer block lets you mix together up to 5 of these sources together using its useful faders and volume controls.

Using blocks again, you can send your audio to multiple places (or outputs). For example, you can broadcast to your radio station, record your show, and listen through your headphones.

To manipulate your audio further, there are plenty of effect blocks you can use to sandwich between your input and output blocks. Various blocks let you adjust the EQ, balance & ducking.

There are also some new blocks such as Magic Boost, which lets you boost just the quieter parts of your audio, and Simple Compressor, which reduces the range between soft and dynamic sounds.

i.e. You can add in a microphone with the 'Input Device' block, you can add in an application such as a music player using the 'Application' block, or you can capture all of the audio played on your computer by using the 'System Audio' block.
