TDA4VM: mcasp audio 3A algorithm

Tool/software:

Hi Ti expert

SDK 0806

I am currently using mcasp in c6x_2. I would like to ask TI experts if they can recommend any application cases of the audio 3A algorithm that can be used in C6X_2？

Best Regards

Hi Eason,

Can you send the documentation that you are referencing?

3A algorithms (in regards to audio) refer to:

Acoustic Echo Cancellation (AEC)
Background Noise Suppression (ANS)
Automatic Gain Control (AGC)

All three are used for improving audio quality.

Best,
Jared

Hi Jared

I don't have any reference documents. Currently, in our c66x, mcasp0 is connected to the mic and mcasp1 is connected to the speaker.

When the data from the mic is sent to the speaker, the speaker will return the reference signal to the dsp.
However, according to current tests, there is an echo.
I would like to ask if there are any related echo cancellation cases that can be applied to c66x?

Best Regards
Eason

Hi Eason,

Are you asking for demo/source code for echo cancellation for the C66X?

Hi Eason,

We don't have any demo/source code for audio applications on the C66x for the TDA4VM.

Best,
