Feedback Study

This project was a collaborative effort with Kevin Hay to explore feedback and self regulating systems as a compositional approach.  In order to gain an understanding of the principles involved they translated Agostino Di Scipio’s ‘Feedback Study’ (Di Scipio, 2003) from a Kyma Schematic to Max MSP. Some of the recordings of their translation can be heard below.

StairwellBMove01 and StairwellBMove02 were recorded in a stairwell (as pictured above) at the Music & Sound research department within the Edinburgh College of Art, The University of Edinburgh at Alison House, Nicolson Square. Glass House was recorded in All Ears Studio, Leith, Edinburgh

Feedback Study: Feedback Loop

‘Feedback Study’ uses a combination of speakers microphones, a mixing desk and Digital Signal Processing (DSP) to generate and manipulate feedback in real time. No sound is present within the memory of the system until it is switched on, whereupon the first feedback tones otherwise known as Larsen are generated and begin to circulate through the system.

‘Feedback Study’ is very much concerned with creating an ecosystem using the audible and spatial characteristics of a given performance or installation space. This is achieved using a complex system of audio feedback loops and self-regulating mechanisms (both additive or contributive and subtractive or limiting) which interact with the resonances and reflections of the given space. Whatever sound is emitted into the space, changes what noises in the future will be made, which in turn stimulates the ecosystem in a new way, ongoing potentially ad infinitum, in an ongoing trade of data and sonic material between the acoustic room or space to DSP engine and back again.
