MESSAGE FOLLOWS:
Dear all, a reminder of tomorrow's seminar...
Tomorrow at 2pm, Vincent Verfaille will present a seminar titled
"Intelligence? It is already in the sound!"
The seminar will take place in room 105 in the Electronic Engineering
Department, Queen Mary University of London, Mile End Road, London E1
4NS. Directions of how to get to Queen Mary are available at
http://www.elec.qmul.ac.uk/research/seminars/ as are details of future
seminars. The room is under access control, so people from outside QM
will need to contact C4DM to get in - the lab phone number is +44 (0)20
7882 5528 and if I'm not available, anyone else in the lab should be
able to help. If you are coming from outside Queen Mary, please let me
know, so I can make sure no-one's stuck outside the doors.
All are welcome to attend. For those unable to attend a video recording
of the seminar should be available on the above website after a few days.
If you wish to be added to / removed from our mailing list, please send
me an email and I'll be happy to do so.
Title: Intelligence? It is already in the sound!
Presenter: Vincent Verfaille
Date: Wednesday 29 July 2009, 14:00, Room 105
Abstract
Digital audio effects (DAFx) are digital signal processing units that
are used to transform some properties of digital sound, both for
creative and production purposes. The development of new DAFx as well as
the refinement of existing DAFx can rely on at least one of the two
following attitudes that are widely using in the community: (i)
goal-oriented: look for or design specific technical solutions in order
to obtain a pre-defined and well-calibrated aesthetic results (e.g.,
time-scaling that preserves both the attack quality and vibrato), or
(ii) exploratory: pervert a technique to explore creative sound
transformations.
This talk will present the exploration of means of control of DAFx using
this second approach. As means of control, we will consider the adaptive
control of effect-also called content-based, feature- driven, or
intelligent control-, where some sound descriptors are computed to
derive the audio effect control parameters. A possible set of sound
descriptors related to the five perceptual attributes (loudness, pitch,
duration, spatial information, timbre) will be presented. Then, for each
one of various audio effects modifying at least one perceptual
attribute, the signal processing technique will be detailed and sound
examples will be played to the audience. Finally, a general mapping
strategy will be proposed, that maps both gesture and sound descriptors
to effect control parameters.
Biography
After a mathematics education at the Institut National des Sciences
Appliquées, Toulouse, France, Vincent Verfaille received a Ph.D. degree
in Music Technology (ATIAM: Acoustics, Signal Processing and Computer
Science Applied to Music) from the Aix-Marseille II University
(Université de Provence), Marseille, France, in 2003. He worked on the
design and mapping strategies for the adaptive and gestural control of
digital audio effects. Thereafter he completed a three year post-doc on
the gestural control of sound synthesis at the Music Technology Area, in
the Schulich School of Music of McGill University, Montreal, Canada.
From then, he worked as a post-doc and then as a research associate on
the sonification of musicians' ancillary gestures, and more recently on
the indirect acquisition of musicians' gestures, i.e. the analysis of
gesture through sound analysis. As of June 2009, Vincent is a freelance
researcher working in the area of audio analysis and processing.
