AEC

This code implents Acoustic Echo Cancellation with LMS/RLS in MATLAB.
I make a GUI program based on MATLAB GUI.I tried the new App designer framework of MATLAB R2017b. Sadly, there isn't an alternative function of spectrogram() ,so I use the old GUI framework back.

• AEC_V2.5 includes the GUI program which consists of Echo_cancel.fig and Echo_cancel.m. For quick test, you can just use the folder to see the result.
• Filter_param is used to find the best params for different types of filters. If you want to learn more about the detail, you can dig up.
• If you know Chinese, just see MATLAB代码说明.pdf. :)

Version: Matlab R2017b. This should work on Matlab R2016b and above.
Since filter function has changed after R2016b, you need to change a bit of the usage of filter functions, say use step() function if your Matlab is not so new.
