Does anybody have a good ap note or direction for incorporating software compression on an audio stream? I'm using the discovery board[STM32F4] to record the audio[8KHz 16Bit] and would like to send over a wireless link to another STM32F4 receiver. I've a radio link that can support 300kbps but in the interest of using the least amount of bandwidth possible, any direction in getting the 128kbps down to a smaller footprint would be much appreciated.

Go to ''Design Resources'', search MP3 on the page

There is an encoder/decoder listed, though not sure of it's usefulness or effectiveness, or it's status wrt licencing.
