This document describes an audio codec with an embedded SigmaDSP processor. It features fully programmable audio digital signal processing (DSP) for enhanced sound processing, including various third-party audio algorithms. The codec also includes a scalable digital audio delay line and high-performance analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). It is suitable for various audio processing and enhancement applications.
The Analog Devices ADAV400 is an enhanced audio processor that integrates high-performance analog and digital I/Os with a powerful, audio-specific, programmable core based on SigmaDSP technology. This integration allows system designers to compensate for real-world limitations of speakers and listening environments through speaker equalization, multiband compression, limiting, and third-party algorithms.
