The notion that reality is to be understood as a process is an ancient one, going back at least to Heraclitus, who said that “everything flows”. The best image of process is perhaps that of the flowing stream, whose substance is never the same. In this stream, one may see an ever-changing pattern of vortices, ripples, waves, splashes…which evidently have no independent existence as such.

Shazam It! Music Recognition Algorithms, Fingerprinting, and Processing

The Shazam music recognition application made it finally possible to put a name to that song on the radio. But how does this magical miracle actually work? In this article, Toptal engineer Jovan Jovanovic sheds light on the principles of audio signal processing, fingerprinting, and recognition, that underlie this apparent marvel of technology.

A great breakdown of how Shazam works. Quite simply, it is using many familiar elements of Analog to Digital conversion with a few nifty algorithms to link the data to the song itself.

Love this diagram. A great source of inspiration for cross platform processing. Think I will be referring to this for ideas...

A previous colleague of mine has been doing some Thermograph work recently and this sent me on a little research hunt. 

We often see the direct results of the presence of heat in an electrical circuit, whether it be your macbook slowly burning through your lap or something more obvious such as an electric heater. However it is quite useful to be able to look at the heat levels across a circuit board.

Diffract light with sound / Acousto-optics

I think the ability to manipulate light with acoustic energy is hard to get your head round but amazing nonetheless.

I will update once i've dug deeper...
