Bio: Kelly Fitz is the principal developer 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, co-developed the Virtual Sound Server, a client/server system enabling data-driven sound computation in interactive real-time environments, and taught electrical engineering and computer science at Washington State University. Kelly is currently a Senior DSP Research Engineer at Starkey Laboratories near Minneapolis, Minnesota, where he is designing and developing audio processing algorithms for hearing aids, and conducting research combining hearing science, psychoacoustics, and signal processing to explore the perceptual consequences of hearing loss and hearing aids.
