RS Audio Codec
This page provides information and some examples for the use of the RS Audio Codec sub board, based on TI's TLV320 chip. This chip provides a high quality audio link out and in to the mbed with IO including: an amplified stereo headphone out, an stereo line out, a stereo line in and an pre-amped mono microphone input. Such a capable chip opens up a lot of options for high quality audio on mbed. 
The easiest way to get something working is to load a test wave file (such as this one or this one) onto a flash drive, plug it into the Lab Board and load up this program:
