Note that everything below may vary depending on the exact DSP firmware used and different variants have slightly different behaviours.


Summary

Some versions of the DSP firmware contain a decoder for the AAC audio codec. Such firmware may be dumped from specific games, like Pokemon X/Y or Rhythm Heaven Megamix. Interfacing with the AAC decoder (sending requests/receiving responses) happens via the DSP binary pipe (pipe 3)
