Audio Hijack Mac broadcast block for Shoutcast and Icecast

Description

Audio Hijack is a Mac audio application that includes a broadcast block for internet radio streaming. The relevant manual section covers sending audio from a Mac to external Shoutcast or Icecast servers. The broadcast feature supports MP3 and AAC streaming and includes controls for station name, genre, and automatic metadata from supported apps or a Now Playing text file. The software can capture and route Mac audio before it is sent to the server. For radio users on macOS, this is relevant as a flexible broadcast utility rather than a full station automation system. Because the broader product is not dedicated solely to radio, it fits best as a reviewed secondary candidate.
