PROFILE
Mika Säppi
Contributed to the savonet/liquidsoap project by building and enhancing core audio processing and streaming features over four months. Delivered true peak measurement and EBU R128 compliance, improving broadcast audio accuracy using C and OCaml. Addressed stability by fixing frame processing crashes and preventing EOF-related failures in external input handling, applying robust error handling and process management techniques. Expanded format compatibility by adding AIFF and WavPack MIME type support, and improved streaming concurrency through clock-threaded state transitions. The work demonstrated depth in backend and concurrent programming, with a focus on reliability, standards compliance, and maintainability across complex streaming workflows.

Jun 1, 2026June 2026 monthly summary for savonet/liquidsoap: Expanded format recognition and strengthened streaming reliability through two focused entregas. Delivered AIFF and WavPack MIME support by updating the default extension mapping, enabling seamless recognition and handling of these formats. Improved streaming concurrency by deferring the cross-operator abort_track transition to its own clock thread, reducing race windows and stabilizing performance under concurrent workloads. These changes broaden format compatibility, reduce runtime issues, and lay groundwork for future scalability. Technologies demonstrated include MIME handling, extension mapping, clock-threaded concurrency, and cross-operator state management. Notable collaboration: co-authored contributions acknowledged in commit notes.
