Broadcast Block

The Broadcast block enables you to stream MP3 or AAC audio from your Mac to an internet streaming server powered by Shoutcast or Icecast. It's perfect for running live feeds of podcasts, as well powering internet radio stations and more.

Read on for information on configuring the Broadcast block, as well as other tips.

Configuring Broadcast

The Setup Tab

You'll start by entering your server's details, provided by your streaming host provider, into the Setup tab. Be sure to enter all these details correctly to enable the Broadcast block to connect to your server.

You'll also select your desired encoding type in the Setup tab. The Broadcast block supports streaming in either the MP3 or AAC formats. When streaming AAC, Broadcast will intelligently switch to AAC-HE (aka AAC+) at 64 kbps and lower.

All of your settings will be saved between launches. Once the Setup tab is properly configured, you likely won't need to change it.

The Metadata Tab

At the top of the Metadata tab, you can set general station information like name and genre, which is likely static.

Below that, you can adjust the track titles which will be embedded in your stream and visible to listeners. Audio Hijack can automatically pull metadata information from supported Mac applications, or from a “Now Playing.txt” file. The Title Format field can be customized to adjust which metadata is shown, and even manually edited for use with sources which don't provide metadata.

Broadcast Tab

The Status tab shows current statistics, as you're broadcasting. These stats are reset each time you begin a new broadcast.

Additional Tips


Audio Hijack's handy Presets feature makes it easy to save server settings for the Broadcast block, then load them into new instances. With Presets, you won't need to re-enter this information each time you use a Broadcast block.

Block Title Field

The Broadcast block features a special Block Title field, which alters the name shown on the block in your Session. If you need to distinguish between multiple Broadcast blocks in the same session, use this field to alter the default block title.
