Shoutcast — Streaming Software

remains a foundational technology for internet radio, powering over 50,000 active digital stations globally. Developed originally by Nullsoft, this client-server protocol transforms local computer audio feeds into global digital broadcasts.

The source client is responsible for encoding audio input (microphones, line-in, or digital files) into a compressed format suitable for transmission. Commonly, software like Winamp with the DSP (Digital Signal Processing) plugin, SAM Broadcaster, or oddcast is used. The source client encodes audio—typically in MP3 or AAC format—and pushes it to the Shoutcast server via a TCP connection. shoutcast streaming software
