Vodec/Codec and serial comms to arduino

Hi Everyone,

I have a halfbaked idea at the moment ;), but I have a project I’d like to get underway that would involve getting an arduino talking to a Vodec or Codec chip - bascially sending it digital data to be converted into audio. Digital data can be PCM or whatever. So what I am looking for is a suitable Vodec or Codec chip that can be talked to by a serial interface like the one on the arduino (probably at the max speed of 115.2 kbps). Anyone know of a suitable Codec?
