Title: Cell-utes and Flutter-Tongued Cats---high fidelity sound  
modelling

Abstract:
The Reassigned Bandwidth-Enhanced Additive Sound Model represents
sound as a collection of simple components having sinusoidal and
noise-like characteristics. Loris is an Open Source C++ class library
implementing analysis, manipulation, and synthesis of digitized sounds
based on the Reassigned Bandwidth-Enhanced Additive Sound Model. Loris
supports modified resynthesis and manipulations of the model data,
such as time- and frequency-scale modification and sound morphing.

Dr. Fitz will discuss analytical methods for collecting and
incorporating noise energy in additive sound models, and will
introduce the use of the method of reassignment in sound modeling to
produce a sharper, more robust representation than is possible using
conventional additive modeling techniques. Sound morphing applications
of the Loris library will be presented and discussed to highlight the
strengths of the Reassigned Bandwidth-Enhanced Additive Model. Future
research directions and applications for Loris and the Reassigned
Bandwidth-Enhanced Model will be discussed, and many exciting sound
examples will be played.

Kelly Fitz received Ph.D. (1999), M.S. (1992), and B.S. (1990) degrees
in Electrical Engineering from the University of Illinois at
Urbana-Champaign, where,in addition to digital signal processing, he
studied sound analysis and synthesis with Dr. James Beauchamp, and
sound design and electroacoustic music composition with Scott Wyatt.
Dr. Fitz is a principal researcher and developer of the Reassigned
Bandwidth-Enhanced Additive Sound Model, and of the Loris software, an
open source library for digital sound analysis, synthesis,
manipulation, and morphing. Previously, he co-developed Lemur, a
widely-used software application for sound analysis, transformation,
and synthesis based on the sinusoidal analysis method of McAulay and
Quatieri, and co-developed the Virtual Sound Server (VSS), a
client/server system enabling data-driven sound computation in
interactive real-time environments, at the National Center for
Supercomputing Applications. Dr. Fitz is currently an Assistant
Professor in the department of Electrical Engineering and Computer
Science at Washington State University, where he teaches C++, Advanced
Data Structures, and Digital Signal Processing.
