FEEDBACK AS SPACE / SPACE AS FEEDBACK

 From the rhythmic, flanging reflections of tiny, narrow corridors to the 
long, deep reverberations of large halls and churches, space has always 
had a deep and inseparable relationship with sound. Sound carries with 
it the identity of the acoustic space in which it occurs: it travels 
through air, bouncing on walls and obstacles, waves of acoustic energy 
being absorbed, reflected, and progressively shaped by the 
characteristics of the room. This workshop focuses on the investigation 
of space and will use the SuperCollider software (if you use PureData or 
MAX/MSP, read further below). 

Participants will be shown the basic techniques for analysing sound and 
extracting meaningful data such as pitch, amplitude, spectral centroids, 
frequency peaks and more. The Fast Fourier Transform will also be 
discussed. An important part of the workshop will be to use audio 
feedback as a way to investigate space and as a tool for systemic 
construction. Audio feedback is space-made-sound, and as such, 
techniques for triggering and controlling it will be introduced and 
discussed.

The workshop will then focus on the acoustic spaces and resonances of 
common-found objects. By means of piezo contact mics, miniature 
microphones and other transducers, the "space" of the objects will be 
explored and investigated, resonant frequencies will be measured and 
feedback structures will be set up between the objects themselves and 
also between the objects and the acoustic space of the room.

Level: Beginner/Intermediate. Some previous exposure to working with 
SuperCollider is preferred, but beginners are welcome. The workshop will 
use SuperCollider mainly, but MAX/MSP and PureData patches will be 
provided for most of the techniques that we will cover.

Tutor: Massimo Scamarcio [ http://massimoscamarcio.com/ ]

Language: English

Some materials will be available at the venue (piezo contact mics & 
miniature mics, mini-speakers, some common objects) Participants should 
bring their own computer with a recent release of SuperCollider 
installed. Audio interfaces are a plus but not required. Participants 
are also encouraged to bring their own materials (mics, preamps, etc) & 
objects (can be anything – from glass vases to plastic pipes, bottles 
and everything in-between).

Sunday   15.12.2013, 12:00–14:30h, 16:30-:20:00h
