So I can convert a m4a to a wav in Terminal by this command:
afconvert --file WAVE --data LEI16 mysong.m4a
I can't get even a simple Calculator to run from within my sketch. I'm getting a error=13, Permission denied. I assume it is a security thing and the operating system is protecting itself from attack. I read something about signing an applet. Would this apply to what I'm trying to do? If so I assume I can't sign it until I'm done and created the applet. How would you test it?
