Built by broadcasters, for broadcasters

What is Mcaster1AMP?

Mcaster1AMP is a professional desktop media player for internet radio — think of it as a modern, broadcaster-grade take on the classic media player, rebuilt for streaming, automation, and AI. It pairs a glitch-free, lock-free audio engine with dual A/B decks, a full broadcast DSP chain, an open Plugin SDK, and on-device AI that narrates and researches the music you play.

Part of the Mcaster1 family

Mcaster1AMP doesn't stand alone. It's one product in a complete broadcasting platform that includes the Mcaster1DNAS streaming server, the DSP Encoder, Mcaster1Studio automation, AudioPipe virtual routing, and the CasterClub community and YP directory. The player speaks the same protocols (ICY 2.2), shares the same DSP heritage as the encoder, and integrates directly with the CasterClub directory through the mc1amp:// protocol.

Who builds it

Mcaster1 is the work of David St. John and is built on real-world broadcasting experience — running stations, managing infrastructure, and serving the internet radio community daily. Every tool, including Mcaster1AMP, is born from problems we hit on air.

Open to developers

The Plugin SDK v2 exposes a stable C ABI so anyone can extend the player with DSP effects, input decoders, and output routing. We host dedicated developer forums for each plugin type and a moderated gallery so the community can share what they build. Start building →
