Using Fire to Visualize Music – A 2D Ruben’s Tube

A Ruben’s Tube is a gas pipe with multiple holes along the way which is used to demonstrate the principle of standing waves. When a suitable frequency is found, areas of high and low pressure (the nodes and antinodes) affect the flow of gas out of the pipe and therefore the height of the flame.

Below is a video demonstrating a 2D planar version of a Ruben’s Tube which makes a fantastic music visualizer!

Compressed Sensing – An Introduction

This week Emmanuel Candès, professor of Mathematics and Statistics at Stanford University has been elected to the American Academy of Arts and Sciences. He is one of the authors (the other being Terence Tao) of the paper which brought about the field of compressed sensing. If you’ve ever done any signal processing, then you’ll know

The Loudness War – Now with Data and Charts!

I’ve mentioned The Loudness War before – squashing the dynamic range of a track to try and boost the loudness to make it stand out – but has a great post with an in-depth explanation and the data to back it up. Paul Lamere of The EchoNest analyzed over 15,000 tracks to measure their loudness (and shows

This is not what We Usually Mean by ‘Drone Music’…

Flying Drone technology has become cheap enough, and more importantly, precise enough to have the sort of control necessary to play mechanical instruments, albeit with some modifications. This is a really cool video of drones doing just that. From the original Wired story – The show comes courtesy of KMel Robotics, a startup founded in
