ANALOG DEVICES’ SIGMADSP AUDIO PROCESSORS PROVIDE FLEXIBLE SIGNAL ROUTING FOR AUTOMOTIVE SOUND SYSTEMS : – ADAU144x SigmaDSP audio processor family handles multiple input signals to ease design constraints and increase processing speed in today’s multi-function automotive audio designs.

NORWOOD, Mass. (PRWEB) October 20, 2008

The new SigmaDSP audio processors include up to eight stereo asynchronous sample rate converters, an S/PDIF (Sony/Philips Digital Interface) transceiver and serial inputs/outputs that support I2S (inter-IC sound) and TDM (time-division multiplexed) formats. Any of these inputs can be routed to the SigmaDSP core or any of the outputs for maximum system flexibility. The SigmaDSP core of the new audio processor family features full 28-bit processing (56-bit in double precision mode), synchronous parameter loading for ensuring filter stability, and 100 percent code efficiency when used in conjunction with ADI’s SigmaStudio graphical development environment, which includes audio processing blocks such as FIR and IIR filters, dynamics processors, mixers, low-level DSP functions, and third-party algorithms.
