Could you build this?
Partial While an internet radio server can be sketched in Python, building a robust, high-performance streaming server capable of handling hundreds or thousands of concurrent audio streams requires non-blocking network I/O, Cython C-bindings, and efficient buffer management.
What it would actually take: The system combines an asynchronous event loop (or epoll/kqueue network reactor) with Cython-compiled C extensions to handle zero-copy ring-buffering, metadata injection (such as Shoutcast/Icecast ICY headers), and bitstream multiplexing to thousands of concurrent TCP sockets. The hard parts are low-latency audio packet scheduling without jitter, memory leak prevention during long-running streams, and graceful handling of slow network consumers without blocking the shared broadcast loop. It requires expertise in network socket programming, multimedia streaming protocols, and low-level C/Python optimization.
