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