Hello! In order to quantify the broadband noise of an audio track, how about implementing an adaptive filter? Does anyone know how can I proceed (matlab or c ++)? I've seen lots of things around and it seems the only viable option to estimate the broadband noise. Thank you in advance. --------------------------------------- Posted through http://www.DSPRelated.com

I have implemented RLS algorithm on TMSC6713 DSK.I am confused with calculation of signal to noise ratio. I have achieved snr by two different means and the results are different.Can any one help me finding the right one. All the samples are aligned and equalized Method 1: I gave speech+noise to the adaptive filter.The speech signal was having a long pause in between.So I recorded the ...

In "Adaptive filter theory" and "Advance signal processing and Noise reduction" they have directly come up with the term gain without stating how they got it. In adaptive filter theory they have jumped from equation 13.16 to 13.18.Same in advance signal processing equation 7.74 to 7.76. https://drive.google.com/drive/folders/0Bz-qIQBWiVixdWlGR0J3d1lELVU ------------------------------------...
