SW solution for Acoustic Echo Cancellation and Noise suppression on OMAP4430+TWL6040

Other Parts Discussed in Thread: TWL6040

Hi,

I have a new project based on OMAP4 platform and Windows Mobile 6.5, it seems no echo and noise cancellation on OMAP4430+TWL6040, I have found the AEC/AER SW on TI's website :  http://software-dl.ti.com/sdoemb/sdoemb_registered_sw/aer/latest/index_FDS.html

then I downloaded aer_gcarmv7a_obj_16_0_0_1_Win32.exe from the site, but this SW  on the request site only supported OS options for installers are Linux and Windows for the PC.

Does someone have any ideas how to install AEC/AER SW on WM6.5?

If not, is there any way to implement echo and noise cancellation on OMAP4430+TWL6040?

Thanks,

Chang-Chih

    I am not sure about a native solution from TI but you can either built it using open source (Speex  is a good reference) or you can purchase a commercial library (SoliCall is a good reference).

    Hi,

    For the statement of AEC-AER on TI website, this SW can remove and minimize the impact of acoustic echo in a "phone" or other similar devices or systems, but AEC-AER installers from TI download site "http://software-dl.ti.com/libs/aer/latest/index_FDS.html" are only for Linux and Windows "PC", how can I apply AEC-AER SW on Windows "phone" which based on OMAP4430 platform?

    I have installed aer_gcarmv7a_obj_16_0_0_1_Win32.exe on Windows PC and generated many source and object files, the libraries for Cortex-A8 are "aer_a.av7A" and "aer_c.av7A", but these two executables seems only for Linux environment.

     

    Does anybody know how to use AEC-AER SW on Windows phone(or Android phone for my reference)?

    Thanks,

    Chang-Chih
