I'm new to arduino and was wondering if it is possible to stack soundcards / shields on arduino hardware and provide those 3.5mm jack with different audio streams at the same time. (2 different songs playing to multiple 3.5mm outputs on arduino)
What I also like to do is split the stereo channel from 1 output to 2 different mono streams. Think about 2 people that are singing a song at the same time in mono to 2 different speakers.
Are those things possible or am I dreaming :-)
Kind Regards, Stijn
