The N64 processes audio on the Reality Signal Processor (RSP), a MIPS-based vector coprocessor. Music is typically played through software audio libraries (like MusyX) that mix up to 16+ sample voices in real-time. Audio quality ranges from compressed ADPCM to high-fidelity PCM depending on the ROM budget.
