Does OMAP4460 ABE support voice background noise cancellation and echo cancellation?

Hi,

As per the OMAP4460 TRM, the ABE supports only the following real time audio processing features namely mixing, muxing, smooth muting, volume control, sampling rate conversion and side tone equalization. It does not support the voice background noise cancellation and echo cancellation. You can access the OMAP4460 TRM at the following link for further details on ABE.

Could you please let me know if you are using Android for your development? May be, you can utilize the Tesla core to perform additional audio processing algorithms.

Thanks & Best Regards,

Hi Venkat,

First thank you for kind hlep.

Yes, we use Android for our development.

I learn little Tesla core. What kind of processing is Tesla core? Hardware processing with DSP in OMAP4460 ? or is it completely software processing done by Cortex-A9 Core? The pure software processing will make ARM core busy. 

Best regards,

Tesla is the DSP itself inside omap4, if you would like to integrate it to your system you may want to look at http://omappedia.org/wiki/RPMsg_Tesla

Hi ICe,

Thanks for your information.

Development with Tesla may require special knowledge of TI  DSP.  It is very difficult for us.

Does TI has CODEC chipset solution for background noise cancellation and echo cancellation?  For example, OMAP4460 + AIC3262.
