Clark:
Watch a new video for 'Superscope'

 

Clark has unveiled a new video for 'Superscope' directed by Vincent Adoxo and premiered via FACT.com. The 12" of the same name will be released 10th March.

Watch the video below or on the Fact website, YouTube and Vimeo.

Pre-order 'Superscope' on 12" vinyl and digitally from,

iTunes / Bleep / Amazon

Directed and produced by Vincent Oliver for Adoxo, the video makes up part of the new 'Phosphor' live show, read the process behind the visuals below.

“An oscilloscope is a type of electronic test instrument that allows observation of constantly varying signal voltages—in this case a stereo audio signal. 

The one we’ve used in this video was found in a skip and is a cathode ray oscilloscope, the earliest and simplest type. The name Phosphor comes from this technology; the inside of a cathode ray's screen is coated with phosphor, the substance that produces green luminescence. In its most common mode, an oscilloscope in action may look something like a heart rate monitor. If you don't know it by name, you'd recognise one if you saw it. Feed it a sine tone you will see a wavy line on its screen.

This oscilloscope is set to X/Y mode, where there is a single constantly lit dot in the middle of the screen. When an audio signal is played into the left channel, the dot will move left and right (across the X axis). Similarly, if an audio signal is played into the right channel, the dot will move up and down (across the Y axis). This is all that happens—a dot moves very quickly. There is no image conversion because there is no image, only a moving dot. There are no frames of animation because there is no animation, just the illusion of moving shapes through persistence of vision*.

A sine tone sent to the X axis (left audio channel) and a second sine tone of the same frequency sent to the Y axis (right audio channel) but 90 degrees out of phase, will produce a perfect circle on the oscilloscope screen. Change the frequency, wave-shape, phase relation, amplitude and number of these tones and you've got yourself a party.

This is the basis of everything we do to create the Phosphor show. Almost everything you see is the product of experimenting with simple tones from test tone generators and synthesisers, layering them up and mixing them together in music performance software.

In the case of the Clark logo and other words, we used a tiny piece of software called rabiscoscopio, written by a hobbyist hacker called Alex (dalpix.com) to convert very simple vector images into wave-shapes that, once combined in X/Y mode, look a bit like said vector image. This is the extent of our 'cheating'. Once the Clark logo is produced, we drag it into our music software for mixing up with the rest of our weird sounds, in our usual experimentative way. No tutti frutti.

*the theory of 'persistence of vision' is disproved but the phrase explains everything so eloquently here."
