While on Sparkfun the other day I found they are selling a new WAV player. The Tsunami Super WAV Tripper. This thing has 8 mono outputs or 4 stereo outputs. It looks like the onboard processor can play multiple sound files at once. I'm setting it up to do room sound effects. Another nice thing is it uses the Qwiic serial communications. One serial cable running between the Red Board Arduino based board and the relays, leds, or sound player. This should make wiring real easy.
