【Overview】

Product Brief The ADAV400 is an enhanced audio processor. Integrating high performance analog and digital I/Os with a powerful, audio-specific, programmable core enables designers to differentiate their products through audio performance.
The audio processing core is based on Analog Devices SigmaDSP® technology featuring full 28-bit processing (56-bit in double precision mode); a sophisticated, fully programmable dynamics processor; and delay memory.
This technology allows the system designer to compensate for real-world limitations of speakers, amplifiers, and listening environments. This compensation results in a dramatic improvement of the perceived audio quality through speaker equalization, multiband compression and limiting, and third-party-branded algorithms.

The ADAV400 supports multichannel digital inputs and outputs. An integrated SRC on one channel provides the capability to support any input sample rate in the range of 5 kHz to 50 kHz, synchronizing this input to the internal DSP engine.
The ADAV400 is supported by a powerful graphical programming tool that includes blocks such as general filters, EQ filters, dynamics processing, mixers, volume, and third-party algorithms for fast development of custom signal flows.
