Don't get us wrong, we love the MP3 Music Maker shield, and the Wave Shield is a dependable classic. But you still need to get an Arduino involved. There's all sorts of tricks with ISD chips or recordable greeting cards, but they never sound any good. So after a lot of engineering and tinkering Adafruit has come out with the Adafruit Sound Board, the fastest way to add audio effects to a project! This is a great sound board for props and costumes!
Best of all, this version even comes with a 2 x 2W stereo class D amplifier! If you don't need an amplifier built in, check out the headphone-out version here.
This product includes the Audio FX sound board, header strip, and two 2-pin terminal blocks. It does not include batteries, speakers, breadboard, or tactile switches.
The Sound Board has a lot of amazing features that make it the easiest thing ever:
The sound board is designed to be simple: it does not have polyphonic ability, can't play MP3's (MP3 is patented and costs $ to license, so this board uses the similar but not-patented OGG format, there's tons of free converters that will turn an MP3 into OGG), isn't reprogrammable or scriptable, and you can't have any other kind of trigger type. However, there's a good chance the project you want to make will work great.
This board is specifically designed for people who want to make props, costumes, toys, and other small portable projects. Check out the tutorial for all the powering options, you can power from 3-5VDC so a 3xAAA battery pack or a LiPoly battery will work well. You can even use a LiPoly backpack to fit on top for an all-in-one rechargeable effects board
