Yan White: Sound

Loop:recycle ~ 2009

In the UK, we produce 434 million tonnes of solid waste every year. As a nation, we only recycle 17.7% of it – one of the worst rates in Europe. Due to the aggressive marketing of new technology and a throw away lifestyle, the amount of electrical waste we throw away is increasing by around 5% each year, making it the fastest growing waste stream in the UK. The UK produces 3 million tonnes of plastic waste each year. Approximately 85% is landfilled, 8% incinerated and 7% recycled. Over 75% of waste electrical goods end up in landfill, where lead and other toxins contained in the electrical goods can cause soil and water contamination.

These loudspeakers were collected over the last 2 months from locations across London.

Using freecycle.org, a site designed to allow any useful item to be collected and re-used for free, and a civic amenity site that sorts re-usable goods, I visited these various locations and recorded my journeys… announcements on the underground, birdsong alongside rail platforms, my own musings and comments on newspaper articles or things I have seen along the way, visits to the dump and freecyclers’ houses.

The collection of 192 sound files is played back randomly through 50 of the collected loudspeaker drivers which are arranged in 8 channels/clusters of varying sizes.

n.

1. A form or part that is folded or coiled.
2. One of the convex folds of the surface of the brain.

In mathematics and, in particular, functional analysis, convolution is a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions. Convolution is similar to cross-correlation. It has applications that include statistics, computer vision, image and signal processing, electrical engineering, and differential equations.

In linear acoustics, an echo is the convolution of the original sound with a function representing the various objects that are reflecting it.

In artificial reverberation (digital signal processing, pro audio), convolution is used to map the impulse response of a real room on a digital audio signal. Common ways of generating this impulse include bursting a balloon and firing a starting pistol, though more accurate results can be achieved by recording playback of a sine sweep, which is then ‘deconvolved’.

These short films together form a ‘book of convolutions’, documents and processes that seek to uncover the secrets of familiar spaces. Many of the sounds in this piece are made from site-specific recordings which have been convolved with the captured reverberations of these spaces, ambience convolved with itself, everyday sounds take on the shape of a handrail, a creaking door, other voices. I am standing in a room, similar to the one you are in now..
