I'm new to sigmaDSPs and working on EVAL-ADAU 1467Z audio signal DSP board,currently. In such a scenario, I have to construct a Noise Auto - correlation matrix present in the input mixture of audio signals through sigma studio 4.2 (for 64 bit OS). Can anyone help me out with this aspect? For instance, helping me with the right block of sigma studio to be used will prove to be beneficial.
Thanks in advance.
I am afraid you will have to explain what you need a little further. I am not certain what you are looking for.
Are you looking to mix several signals and have the mixer adjust the gain for the person who is talking so they are loudest?
Are you looking to cancel noise from several channels of audio and have the noise cancellation automatically adapt to the background noise?
Dear Sir, Thanks for your reply. As you have pointed out, I'm looking for noise cancellation present in the channel by means of constructing a correlation matrix. And, in fact, I'm looking for exactly the same procedure you pointed out secondly.
Could you suggest me more on this?
I will refer you over to Ken.M. He takes care of the noise reduction inquiries.
