Gal Gun 2 (Switch) audio encoder

[Pokemon1995]

It is possible to convert .wav sound files to the same audio format which Gal Gun 2 (Switch) used?

I´m not am programmer but i really want to mod the music in Gal Gun 2 (Switch) but i can not recreate the sound files. I know it is some form of .dsp but that really all i know.

I have made a fork that converts to DSP GC-ADPCM that Switch games support natively. Tested on 9-nine
