minimp3's sliding-window frame confirmation could spuriously discard real frames near the tail of a not-yet-full window, losing ~5.5% of a real VBR file's content even at a tuned 256KB window (~0.3% residual) - audible as the whole track finishing early with stutters at each drop. libmad's mad_stream/mad_frame/mad_synth API reports "need more data" (MAD_ERROR_BUFLEN) and "genuinely bad data" separately rather than overloading one return value, which was the actual ambiguity minimp3 couldn't resolve. Verified against the same real file with a 32KB window (vs minimp3's 256KB): frame count and duration match the Xing header exactly. Confirmed building for Linux, GameCube, and Wii (the latter two via the project's real devkitPPC/libogc Docker toolchain) - libmad ships inside libogc itself on Dolphin, no separate fetch needed there. libmad is GPL-licensed, unlike the rest of this MIT project - a deliberate tradeoff, noted at each site that pulls it in.
