AVR sound can be generated from a simple
design on a development board, to something which gives full digital
sound playback. It is possible to stream MIDI files as playback, all
possible through some simple coding of your AVR chip. Some of the range
of Atmel AVR micro controllers, actually come with sound generating
firmware installed upon them, but the ability and beauty of these micro
controllers, is the fact that you can tweak and recode anything to your
own design. It is possible to create a playback system for an iPod or
any mp3 player, through which the AVR chip can emulate the sound into
full audio waves for the ear to hear. The fun of such projects is in
designing and building such things yourself. It is also possible to add
sound effects and voice samples to your AVR micro controller, to you
give your project a little extra personal touch. You can get full
output sound in stereo, by integrating a headphone output jack into
your circuitry, which will be controlled by the programming done with
the micro controller itself. There are many ways to approach the
development of producing sound and playback of MIDI files through a
controller, and experimenting with AVR sound is a good way to approach
the coding of micro controllers. |
