Before the last update, devkitpro release 27, we had to do sound using SOX in tht terminal window.
Basically having the right setup you can use .wav files.
Auke asked me where the soundbank.h file could be found. Well this file is generated by the MAKEFILE itself:
there is a special line for this in the MAKEFILE:
# rule to build soundbank from music files
soundbank.bin : $(AUDIOFILES)
@mmutil $^ -d -osoundbank.bin -hsoundbank.h
and you can find the soundbank.h in the build folder, after buidling (make command in Programmer’s NotePad)
Also the header file for the .wav files are generated by the MAKEFILE.
export AUDIOFILES := $(foreach dir,$(notdir $(wildcard $(MUSIC)/*.*)),$(CURDIR)/$(MUSIC)/$(dir))
and the folder where to find the sound data:
MUSIC := maxmod_data
The interplay between header files of media (image and sound) and the MAKEFILE is something you have to get used to. Using the MAKEFILE template everything is taken care of in principle.
All is explained excellently on this page: http://maxmod.org/ref/tut/dsprog.html
