Altacast

Altacast is a software program used primarily for live audio streaming, often employed in internet radio broadcasting. It functions as a source client, encoding audio from various sources (microphones, soundcards, etc.) into formats suitable for online streaming, such as MP3 or AAC. Altacast then transmits this encoded audio to a streaming server like Icecast or Shoutcast, making it available to listeners over the internet.

Altacast is notable for its lightweight design and relatively straightforward configuration, making it accessible to both experienced broadcasters and those new to online audio streaming. Key features commonly include support for multiple encoders, metadata management (allowing the display of song titles and artist information to listeners), and the ability to connect to multiple streaming servers simultaneously. It often serves as a free and open-source alternative to other commercial broadcasting software. The software is typically used on Windows operating systems, though compatible applications may exist for other platforms. The primary purpose is to convert and transmit live audio for a network broadcast.
