Module ctru::services::ndsp

NDSP (Audio) service.

The NDSP service is used to handle communications to the DSP processor present on the console’s motherboard. Thanks to the DSP processor the program can play sound effects and music on the console’s built-in speakers or to any audio device connected via the audio jack.

To use NDSP audio, you will need to dump DSP firmware from a real 3DS using something like DSP1.

libctru expects to find it at sdmc:/3ds/dspfirm.cdc when initializing the NDSP service.
