    If you check out some of the other stuff on her blog, it’s really fascinating. Something I wish I had more free time to learn about. I have no idea where to start.

      I agree. Fascinating stuff. You might be interested in introductions to digital signal processing.

      The Scientist and Engineer’s Guide to Digital Signal Processing is available free (or on Amazon). It’s a good introduction with concepts explained through Fortran examples. For something more recent, I’ve heard good things about Understanding Digital Signal Processing.

        Hmm, I think you mean BASIC rather than Fortran.

          Indeed. My apologies. It’s been a while since I opened the book.

          Don’t let the choice of language be a turnoff to anyone though. The author intentionally picked “a simplified version of BASIC” because he found it the most straightforward to “concentrate on the algorithms and techniques, without being distracted by the quirks of a particular language”. I remember finding it very effective and helped drive home the concepts without getting lost in the mathematics.
