Dear Support Team,

 

Q1: I want to using ADAU1761 for a audio product, and the noise reduction algorithm is necessary. I have a single channel design just for evaluate the NR algorithm as below photo, it is work well.NR work well for single channel.jpg

 

but, I want the NR algorithm can effect 2 channel for the stereo audio, so I place 2 NR blocks, but there is a error info: RAM address exceeds:4096. pls help to advice how to solve this issue? Or do you have a solution can achieve the NR function for stereo audio?

Q2: I want the DSP chip can self boot by external EEPROM, and the NR algorithm is necessary, seems I can't find a chip can fill the requirements, could you pls recommand a DSP chip both support EEPROM self boot and NR algorithm? tks
