For our new microphone design, we’re using the ADAU1761 codec.

The sampling frequency is 48kHz.

One of the features, need to be implemented is noise reduction. We going to use this feature for the ADAU1467 DSP. Do you have similar algorithm for the ADAU1761?

Thanks,

Helo,

There is a noise reduction algorithm for the ADAU1761 but it only runs at 16kHz sample rate, See below
