Holywell Coombe (Sweeping Filter)

This piece consists of a field-recording made in Holywell Coombe, an area of countryside on the outskirts of Folkestone town which is part of the Folkestone to Etchinghill Escarpment SSSI.

A steadily oscillating band-pass filter explores the variety and interplay of sounds concurrent in the landscape (from aircraft to insects) as it passes through the frequencies within which each sound operates.
A similar use of this technique can be heard in the previous work Green Language.

Holywell Coombe (Sweeping Filter) was broadcast on Radiophrenia, Glasgow CCA, September 2023.
