Hi all,

I want to use AER on OMAP L138 processor for VoIP application.

I want to analyse the audio call recording files by feeding to MATLAB.

I have downloaded the AER bundled package and tried to use the Nonliner analysis tool.

But unable to get any results using the sample files in the given package.

Could you please help me how to use AER for analysing echo in my application.

thanks

Lenin

    Hi all,


    I tried the Nonlinear echo path analysis tool in the TI AER bundled package and i am able to get the results with the sample audio file given with the package.

    But when i try to feed my own audio files for testing, iam getting an error "threshold is very high".

    After this error the tool gets shut down automatically.

    Can anybody please suggest me in this issue.

    Thanks,

    Lenin

    Hi Lenin,

    You'll need to provide the nonlinear tool with both the reference signal and the returned echo captured from your device. Please refer to the nonlinear tool document - tools\nl_tool\NonlinearTool.pdf for detailed instructions.
