Common question to ponder...they are both fine. It is a sort of which came first, the chicken or the egg question. I agree with all of the responses. Pavan, Scherier,...

Yes, you can implement biquad filters in Simulink using frame-based processing. That said, it's not very intuitive. There are problems, all of which can be addressed.1....
Since you are the implementer of said embedded system, that means you have the source code and I'm assuming an editor/debugger to go with it. If so, I recommend...

Similar to lifeatthesharpend's comment of "a picture is worth a thousand words" suggestion, I would second that and double it. By doubling it, I mean sharing an...

If you want to know/see/understand the algorithms (there are two options, ZOH and Tustin) involved in detail, you can always step thru the source code. I'm assuming...
I haven't tried something like this before but it is an interesting re-use/efficiency question. The first question I'd ask is a sort of step back question. I'm assuming...
I agree with Dr. Mike. What he suggests is an amazing Jedi-mind trick that works surprisingly often! Talk yourself to the answer. The other thing you essentially...

Hi rober_lr,It's a non-trivial problem in general as you've noted and I don't have anything resembling an out-of-the-box solution, particularly nothing Python-based....
You can download the cross-spectrum based Simulink example from github by going to the YouTube link I provided and expanding the "description" section. There...
Hi Hao,I see a number of responses and observations on symmetry of the PSD and the associated realness of the IFFT. All of this, the theory, is true. However, I...
I think fharris answered your question so I would stick with that. I lack significant domain expertise in acoustics and as such I can't offer such specific advice....

Hi Kaz,I am 100% confident you know the difference between smearing and mirroring but I thought it worthwhile to clarify the terms/effects because your limiting...

Hi Kaz,There have been a number of responses here along the same lines so my apologies if I'm not adding much of anything new. First, the snippet of MATLAB code...
