Lemur - A Tool for Timbre Manipulation

Kelly Fitz, Lippold Haken, and Bryan Holloway CERL Sound Group, University of Illinois 103 S. Mathews, Urbana IL 61801, USA lemur@uiuc.edu Abstract We will present Lemur, a system for generating and manipulating sinusoidal models for sampled sound, implemented as a MacintoshTM program. Our system uses an enhanced McAulay-Quatieri (MQ) style analysis for modeling sampled sounds. The system provides tools for time and frequency scale modifications, partial editing and pruning, timbre morphing, and many other manipulations in the model domain. Time-variant manipulations may be performed using control files. Third-party implementations of the Lemur model will be discussed. A real-time controllable implementation of a bandwidth-enhanced synthesis algorithm will be demonstrated.
