GitHub repository tau-org/tau-tower introduces a webradio server designed for broadcasting audio streams to web clients. The project streams audio from tau-radio instances and serves HTML audio streams compatible with standard website audio tags. Built as an alternative to Icecast, it enables live audio distribution across the internet with minimal setup requirements.

Funding comes through NGI Zero Core, supported by the European Commission's Next Generation Internet program. The server requires deployment on remote infrastructure like AWS or Digital Ocean droplets, though users should note RAM limitations on smaller instances. Installation uses Cargo, and configuration involves setting listen and broadcast ports along with CORS policies for stream rebroadcasting.

The architecture pairs tau-radio running locally on user machines with tau-tower hosted remotely. Audio captured from system devices flows through optional TLS/SSL proxies before reaching the broadcaster. Integration extends to Asciinema for combining live terminal sessions with audio backgrounds, requiring specific CORS endpoint configurations.

This represents a lightweight approach to web-based radio broadcasting, particularly useful for developers creating interactive streaming experiences or educational content that combines terminal demonstrations with live audio commentary.
