Abstract
Audio data processing circuitry 300 includes a plurality of analog inputs 101 for receiving analog audio data and a digital input 105 for receiving digital audio data. A analog mixer 312 mixes analog data received at said plurality of analog inputs 101 to generate a mixed analog audio stream. An analog-to-digital converter 313 converts the mixed analog audio stream to a digital audio stream and a digital mixer 315 mixes digital data received at the digital input 105 with the digital audio stream from the analog mixer 312 to generate a mixed digital audio stream.
