Audio Signal Processors

Analog Devices' proven analog and digital technology delivers audiophile performance for the entire world of audio. SigmaDSP® allows designers to use the SigmaStudio graphical tool with an audio digital signal processor without assembly or C coding. Many SigmaDSP processors also integrate high-performance audio ADCs and DACs to build a full audio system-on-chip. ADI's SHARC® Processors are the leaders in quality audio processing and the Blackfin® Processors in mobile multimedia. Check the SigmaDSP FAQ for any questions you might have.
