One customer need a reduction function block on ADAU1761.
In the customer application, some certain audio stream have like a white noise after ADAU1761.
They try to remove this noise using Noise Reduction Block but this block only support 16kHz.
They also try to use LPF, HPF but basically this white noise mixed with audio sound bandwidth, so not work.
Is there any functional block that support 44.1kHz and monoral sound?
Thank you for your help in advance.
