It stores raw DSP data in the 16 MB of ARAM along with audio data, but ARAM also can store extra data such as textures, animations, for example.

Macronix DSP microcode is written in assembly you will require a assembler to assemble your code. asnd & aesnd is the homebrew dsp microcode that exist in devkitpro for the Nintendo GameCube.
