We are going to implement echo cancellation function in ADAU1761 , It will be used for karaoke and education system.
We finds the NLMS module in sigma studio and also test it by real condition , but the test result is not good. We got some volume & Quality distortion when I use the NLMS module.
As I know , some 3rd party also design algorithm for SigmaDSP, Could you help to introduce the 3rd party who design the AEC algorithm to us?
or , Could you give me some advise for NLMS module usage?
