A company recently implemented an effective solution for echo cancellation (AEC) in their product by porting a MATLAB/Octave algorithm to C. The team considered three possible technical solutions, including using MCU detection, CPU vendor-provided algorithms, and open-source options like Webrtc and Speex. After analyzing the performance of these algorithms, they decided to use an open-source AEC algorithm from GitHub and Gitee. The chosen algorithm was able to effectively eliminate echo in their product's double-talk scene.
