The author explains why standard players, HLS/DASH, and full-file downloads all failed to meet the constraints, then details the custom solution: virtual chunking (HTTP Range requests against a single MP3 file), MP3 CBR encoding with 9-frame warm-up overlap to handle bit-reservoir artifacts, a compact binary descriptor format, a native C++ playback engine built on Superpowered via an Expo module, libcurl for cross-platform transport, a deterministic prefetch priority algorithm based on section-lock state, and a thread model that keeps all timing-critical work off the React Native bridge. The system achieved beat-aligned, artifact-free section switching and track transitions on 3G-class connections. ## Full article daily.dev links to this article rather than hosting it.
