Hi all,

I am working on OMAP4460 (Blaze tablet 2) running Android Jelly beans.

I wanted to know , how do i plugin my AEC module into the Android framework (Audio HAL and below) ?

i.e. Is it a ALSA plugin ? HAL plugin ?

There is some reference to echo cancellation in Audio HAL and also in the ALSA kernel.

Please give more information on how to plug echo cancellation software.

Regards,

Hi Shrish,

It depends of what your AEC is, is it a kernel module or a library?

If you mean at user space probably you want to ask here: android-platform@googlegroups.com

Thanks ICe for the info.

I see there are some effects in the {MYDROID}\system\media\audio* folder.

Can you please explain how and when are these used ?

Regards,

I am not much familiar with those files since it is pure android and we don't support it. But my guess is that those are libraries used to give some effects to the audio.

For more information you can ask the android platform mailing list on what you are trying to achieve so they can give you more tips on what to do at user space.
