Macronix DSP is a 16 bit programmable DSP coprocessor in the Nintendo GameCube\Wii\Wii U, it was manufactured by Macronix. It has it's own ADPCM hardware decoder to off load the DSP. 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.
JAudio(JSystem) DSP microcode also seems to contain these types
SRC_SQUARE_WAVE SQUARE_WAVE_25PCT SAW_WAVE PCM8 PCM16 DSP-ADPCM
