AUDIO FEEDBACK AND ACOUSTIC SPACE
(lecture by Massimo Scamarcio)
Audio feedback has been used as a tool by numerous electronic /
electroacoustic musicians, composers and performers, as well as sound
artists. This talk will address some of the potentialities of audio
feedback as well as its strong relationship with acoustic space.
Massimo Scamarcio will discuss the basics of feedback theory and audio
feedback, showing how to trigger and control it using the Supercollider
software, and focusing on some of its compositional and performative
possibilities.

Sorry for cross-posting, posted it to off-topic first, it fits here better
though.
Medea Electronique announces an open call for works for the upcoming
'Electric Nights' Festival, a 27hour long festival of experimental
electronic music, DIY and noise art.
Check the call here

Greetings,
My new work (in pure data) is now available for listening, with
accompanying documentation at:
www.petervanhaaften.com/livingcircuits.shtml<http://petervanhaaften.com/livingcircuits.shtml>
------------------
An entirely autonomous performing/composing instrument, using 12 tone
serialism.
Written in Pure Data, an internal variable score defines a semi-fixed
structure. A 12 tone pitch matrix is automatically built, and the various
transformations, inversions, and retrogrades are triggered to playback via
a Euclidean rhythm generator.
Audio output is routed back into the system for automated processing and
spatialization via scored event triggers, and weighted random number
generators.
Every performance is unique.

Thanks for looking!

Hi List,
An update to PDP:
http://zwizwa.be/pd/pdp/pdp-0.14.1.tar.gz
0.14.1:
Port SCAF MMX code to x86_64 ABI
Revive pdp_opengl (3dp)
Bugfixes
SCAF (Simple Cellular Automata Forth) is ported to x86_64 ABI. It still
uses the old MMX 64bit integer code which makes little sense on x86_64,
but at least it works.
3dp mostly works. Some known issues in corner cases
(pdp/opengl/doc/examples):
- example05.pd : multiple window render contexts causes crash
- example06.pd : bug in scaf CA grid -> texture conversion ?
The texture feedback also looks a little weird - not as I remember it.
Enjoy
Tom

We have 4 seats left available for this workshop that is to start
tomorrow.

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).
Dates:
Saturday 14.12.2013, 12:00-14:30h, 16:30-20:00h
Sunday 15.12.2013, 12:00–14:30h, 16:30-:20:00h

COMPLEX DYNAMICAL (ECO-)SYSTEMS BASED ON NONLINEAR FEEDBACK NETWORKS:
THEORY AND PRACTICE
In this workshop, complex dynamical feedback systems for human-machine
interaction performance, autonomous sound installations and
non-conventional sound synthesis will be discussed and put to practice.
The workshop will be divided into two main parts:
First, a theoretical part will cover the properties of feedback systems
from a systemic and cybernetic perspective within the framework of
emergent and complex phenomena, along with theoretical concepts related
to such an approach for creative practices.
In the second part, Dario Sanfilippo will present some of his works and
techniques and such systems will be implemented through the Pure Data
programming environment trying to give the possibility to each
participant to personalise their own systems. During the implementation
process, technical and theoretical aspects of the techniques used will
also be discussed.
Requirements: A laptop with the last version of Pure Data-extended
installed and any kind of microphone.
Tutor: Dario Sanfilippo
Dates:
Saturday 07.12.2013, 19:00-21:30h
Sunday 08.12.2013, 12:00–14:30h, 16:30-:19:30h

Dear all,
if you happen to be in Dresden this weekend. On Thursday and Saturday night
I'll be at CYNETART Festival performing a new version of Hypo Chrysos, an
action art piece for Xth Sense biophysical media, multiple loudspeakers and
subwoofers, and real-time visuals. Info below.
wishing you well,
M
\\\\\\\\\\\\\\\\\\\\\\\\\\
in occasion of
Metabody Performance Night @ CYNETART Festival
Hypo Chrysos v.2
action art for vexed body and biophysical media (Xth Sense)
"During this twenty minutes action I pull two concrete blocks in a circle.
My motion is oppressively constant. I have to force myself into accepting
the pain until the action is ended. The increasing strain of my corporeal
tissues produces continuous bioacoustic signals. The sound of the blood
flow, muscle contraction bursts, and bone crackling are amplified,
accumulated, distorted, and played back through 4 loudspeakers and 4
subwoofers using the biophysical instrument Xth Sense (Pd-based), developed
by the author...
When the performer’s muscle vibration becomes tangible sound breaching into
the outer world, it invades the audience members’ bodies through their
ears, skin, and muscle sensory receptors. The sound makes their muscles
resonate, establishing a nexus between player and audience. The listeners’
bodies, the player’s body, and the performance space resonate synchronously"

Hello,
I am happy to announce version 0.15.0 of PuREST JSON, code name: The API
they are a-changing.
PuREST JSON is a library for working with RESTful HTTP webservices, and
JSON data.
Authentication and authorization for webservices are available with
basic HTTP auth, cookie authentication, and OAuth. As an example for
OAuth authenticated webservices, a Twitter client is included.
Changes in the new version:
- Cancellation is now faster
- Switch to json-c 0.11
- Refactoring of code
- Breaking changes:
-- [oauth] and [rest]:
* [write( method is now called [file(
* [url( method is now called [init(
* init errors only output to console
* changes to status outlet:
** on success output bang
** on HTTP error output numerical HTTP status
** on cURL error output list: error code and message
-- [rest-json] has been removed
-- [json-decode]:
* string values will not be checked for numbers or boolean
If your build tool or platform does not have json-c 0.11 available, use
the branch json-c-0.10 for compilation.
