The circuit to connect a speaker or Active buzzer to your microcontroller is a fairly simple one. Please note that I am using a 0.5W speaker with a voltage requirement of 1V at 1KHz and an impedance of 8 Ω. If your voltage requirements are higher, you can use a transistor with an external power source to amplify your signal.

The Atmel AT32UC3A3 supports audio sample rates up to 50 kHz and adds to its already efficient instruction pipeline a set of DSP instructions. It can communicate with audio ADCs over the I²S bus and even includes its own bitstream DAC, making it an ideal platform for audio playback devices.
Microcontroller Compatible Audio File Conversion

Small microcontroller audio projects are designed to play very specific types of audio files. If your music sample is in MP3 format, or 44KHz .wav or if you have grabbed a sample from a source (or the Internet) and do not know how it was encoded, you'll want to convert it to the right format.
