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.
Not directly, it is the processing power of the normal Uno that you are going to have trouble with. Also writing a program that accesses and feeds different SD cards and D/As in an apparent multitasking form is not so easy either.

Wave shields are mono only.
You could use MP3 modules and just have the Arduino push the buttons.

Shows two audio files being read at the same time but the quality is very poor due to the method of outputting the sound using PWM.
