Creative Artificial Intelligence
Architecture Research Laboratory
Distributed Intelligent System for Telematic Music Applications
is a project funded by the National Science Foundation within the CreativeIT program. Within this project, we are interested to develop intelligent agents for improvisational music collaborations over the internet.

Complex communication for co-located performers within telepresence applications across networks is still impaired compared performers sharing one physical location. This impairment must be significantly reduced to allow the broader community to participate in complex communication scenarios. To achieve this goal, an avatar in the form of a musical conductor with forms of artificial intelligence will coordinate between co-located musicians. Improvised Contemporary Live Music of a larger ensemble, serving as a test bed, is arguably one of the most complex scenarios one could think of, because it requires engaged communication between individuals within a multiple-source sound field that also has to be considered as a whole. The results are expected to inspire solutions for other communication tasks.
The avatar system will actively coordinate co-located improvisation ensembles in a creative way. To achieve this goal, Computational Auditory Scene Analysis (CASA) systems, to allow robust feature recognition, and Evolutionary algorithms, for the creative component, will be combined, to form the first model of its kind. The research results are expected to be significant by themselves and are not bound to telematic applications. With regard to the latter, the proposed system will have a clear advantage over a human musician/conductor, while intelligent algorithms are clearly lacking behind human performance in most other applications, especially when it comes to creativity.
Triple Point (Pauline Oliveros, Jonas
& Doug van Nort) is a 2009 trio with a post-genre approach well inclined to the Deep Listening practice. The trio work is based on the development of the new IT tools
which are developed within their CreativeIT grant from the National
Science Foundation. The band derives its name
from the thermodynamical point in the phase diagram where all three
phases of water exist. Figuratively, this is where the trio operates exploring musical spaces and boundary conditions where
contrasting ideas and streams can co-exist, while expanding the
vocabulary of musical instruments acoustically (Braasch on soprano
saxophone) and electronically (Oliveros, digital accordion and
Expanded Instrument System, EIS, Doug van Nort on laptop and GREIS). For many decades Pauline Oliveros has been actively
expanding the voice of her main instrument, the accordion. Given the
limited natural possibilities of this instrument with respect to sound
(fixed tuning, no pitch bends, narrow variety in overtone spectrum),
Oliveros has begun half a century ago to alter the sound of her
instrument using tape delays and other electronic devices. Van Nort’s
work is based in digital signal processing, transforming Oliveros’,
Braasch’s an his own sounds using Granular Synthesis,
psychoacoustically-motivated sound analysis tools and Genetic
Algorithms to explore new musical textures and timbres.
Here is another excerpt from our concert at the Emily Harvey Foundation (March 12, 2009, New York City), in which a number of new developments from the CreativeIT project were presented:

Tintinnabulate & related Courses
Students are able to participate in the project through seminars that are linked to the project. The following excerpt shows a concert at EMPAC and Second Life with the RPI ensemble Tintinnabulate.
Tintinnabulate and our CreativeIT project play an important role in our ongoing seminar on Music Composition, Improvisation and Telematic Music. The current seminar is:
"Experimental Telepresence" (ARTS 4962/6962, instructor: Pauline Oliveros, co-instructors: Jonas Braasch, Doug Van Nort) Spring, 2010
and these were the related seminars in the past:
"Composition, Improvisation & Performance" (ARTS 4964/6964, instructor: Pauline Oliveros, co-instructors: Jonas Braasch, Doug Van Nort), Fall 2009/10.
"Experimental Telepresence" (ARTS-4962/6962, 4 credits, instructor: Pauline Oliveros, co-instructor: Jonas Braasch), Spring 2009.
"Mixed Reality Seminar" (ARTS-4961/6961, instructor: Pauline Oliveros, co-instructor: Jonas Braasch), Fall 2008/09.
