The 2008 Audi A5 Coupe is attracting attention for its interior, as well as its style and handling. A big part of that stems from the Audi Symphony and Concert digital radios, which feature a six-CD changer and a MultiMedia Device Interface for connecting MP3 players. An optional Bang & Olufsen surround sound amplifier and digital radio round out the sound sources. The Analog Devices Inc. Blackfin DSP chip is the engine for all these features, handling the audio decoding and processing functions, communications protocol processing and all control processing. The ADI chips also handle the driver interface, which is increasingly important as drivers have more electronics to control.
