% Ideally "resamples" x vector from s to u by sinc interpolation
function y = sinc_interp(x,s,u)
    % Interpolates x sampled sampled at "s" instants
    % Output y is sampled at "u" instants ("u" for "upsampled")
    % (EXPECTS x, s, and u to be ROW VECTORS!!)

    % Find the period of the undersampled signal
    T = s(2)-s(1);

Disabling GNOME Tracker and Other Info

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/

After discovering it chowing 2 cores, I decided to go about disabling it.

Experimenting with pitch detection and spectral estimators

See the question and discussion on StackOverflow: How to get the fundamental frequency using Harmonic Product Spectrum?.

We’re trying to estimate the fundamental frequency of a voiced A4 note (440 Hz). (See the question for link to audio clip.)

Harmonic product spectrum

Result: full data, 0 to 2 KHz

The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:

Windows

1. The first step depends which version of Windows you're using:

• If you're using Windows 8 or 10, press the Windows key, then search for and
