Combining Adaptive Filtering and Complex-valued Deep Postfiltering for Acoustic Echo Cancellation

In this repository you will find exemplary results from our ICASSP paper Combining Adaptive Filtering and Complex-valued Deep Postfiltering for Acoustic Echo Cancellation.

In addition, you can access our implementation of the proposed complex-valued postfilter in the folder source_code.

Audio examples

Here you will find five different examples produced using the synthetic test dataset provided as part of the ICASSP 2021 AEC Challenge:
