Simple Fourier transform in Javascript I’m gearing up to do some signal processing stuff, and I thought it would be good to brush up a little on some of the mathematical concepts. I’m very familiar with the uses of the various transforms including the Fourier. However, although I’ve used others’ implementations of the FFT algorithm, I’ve never attempted to write…

The Hyperlink: the power of simplicity I recently came across the Ubiquity plugin from Mozilla labs. This project is championed by Aza Raskin , son of the late Jef Raskin of Mac UI fame. The Raskin legacy is a powerful one, and I’ve found personal inspiration on the pages of his site (Update: the articles on Jef’s personal site seem…

I’ve gleaned a lot of valuable information from these sources, but in the back of my mind there are typically also a lot of bits of information that I fill in or gloss…

EcStatic: An advanced subtractive synthesizer for Reaktor I’ve recently been going through a lot of past audio work and reviewing my approaches/techniques. I have a lot more ideas, but I’ve been away from it for a long time. Hopefully I can create some new stuff, but in the meantime I’m cleaning up several synths for release that think would be…

Will handwriting input ever be important again? Recently I’ve using my old tablet PC for sketching out UI designs, and I am constantly reminded how bad the handwriting recognition is on Windows XP Tablet Edition.
