Hai,
In one of our project we are using analog circuits for audio signal processing. But with these circuits we are facing lot of problems like humming noise, howling noise, sensitivity issue(AGC needed). So now we want to go with a digital system which includes a Audio Digital Signal Processor or any other Audio Codec. Can you suggest us any Processor or Audio codec that can be used to improve the audio quality and sensitivity. This is a very urgent requirement.
Also please find the attached system block diagram
Regards
