Noise removal for ADAU1452

Hello jongkim,

What kind of noise are you looking to remove?

What is your application?

Dave T

Hi Dave,

I am trying to remove car engine noise or aircraft jet engine noise.

Thanks in advance for your reply.

Hello jongkim,

Is the product a headphone application that is battery operated or is it a product running inside a vehicle where there is a lot of space and a lot of power available?

Dave T

Hi Dave,

We have both applications - in car and headphone.

I was testing ADAU1761, it works, but the delay was too noticeable.

So, I tried ADAU1452 hoping faster process, but ADAU1452 didn't have the noise removal block in sigmastudio.

Hello jongkim,

I have some options for you but I will have to contact you directly. So expect an email from me.

Dave T

Hello namsp,

You already have a program that looks good. We have been discussing this on this thread:

https://ez.analog.com/thread/99885-please-help-me-with-adau1701

Let's continue over there.

I had asked some questions.

Hello, Dave.
I have the same problem. In my application (noise reduction in the cockpit) I plan to use ADAU1452 but in SigmaStudio for this DSP there is no Noise Removal function.
Could you suggest ways to solve this problem?
Thank you.

Hi Dave,

Same question here, could you send me the options?

P.S. Wouldn't it be better to post the options either here or somewhere on the AD wiki to be found by everyone?

BR,

Harjo.

Hi Dave, I am also interested in noise removal options for ADAU1452. If you could drop me a line that would be great.
