You could probably simplify/speedup the line by doing proper matrix algebra instead of just dot-products and sums, but that would require spending 5 minutes to actually...

A moving average followed by a downsampler fits in with general dsp integer downsampling. The lowpass filter is a rectangular filter which (as you say) turns into...

The basic power of two factorization that describes the FFT in the first place shows how to use two N/2 FFTs (+ pre or post processing) to do one N fft. By doing...

This blog post seems to cover some of the basics:https://medium.com/@baranov.mv/how-i-was-listening...Or you might go straight to one of the Farina papers:http://pcfarina.eng.unipr.it/Public/Papers/226-AES...For...

While tuition is free, eating and sleeping is not. Scholarship + loans covering cost of living added up to a debt of about $30.000. This loan is different from...

I wonder if cepstrum analysis might be suitable for this task, ala:http://people.ee.ethz.ch/~spr/f0_detection/

>When it comes to IEEE-published papers you will see VERY VERY few "papers that are easy to follow and also easy to reproduce in MATLAB."I think that there...

If you have an object having linear movement from one frame to the next, there is no reason to expect its movement to be an exact integer amount of pixels. Rather,...
