Adding quality audio to an electronic project is surprisingly difficult. People tend to end up either using low-quality ISD chips (you might get 8Khz sampling rate for 30seconds out of these, if you're lucky!) or mucking around with trying to control a CD or MP3 player. Although it's possible to generate audio direct from a microcontroller using a PWM output, the quality is often low and its hard to fit a lot of music in an EEPROM chip. You can buy an embedded MP3 player board, but they're either expensive or difficult to use!

Here is a shield for Arduino that solves many of these problems. It can play up to 22KHz, 12bit uncompressed audio files of any length. It's low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.
