Encoding for Auditory Representations (EARs) Workshop at the University of Washington, Seattle, 22-23 August 2011


This is an intentionally small, focused gathering of top auditory and signal processing experts, with an intensive dialogue towards advancing audio and auditory signal representations. We, an intentionally interdisciplinary group, will have key open application challenges, experimental findings, and novel underlying computational model theory, to discuss.

Attention will also be given to neural encoding of auditory signals, from the periphery to the central, audio assistive devices, and psychophysical work relating perception and those areas' interplay with recent new mathematical and engineering signal representations. Dynamical systems and non-stationary signals viewpoints will be stressed, since they are presumed to be so central for audition and speech perception.

This EARs workshop also served as an honorarium for William H. Huggins (1919-2001), who was a pioneering auditory theorist in the 1950s, and the first auditory researcher affiliated with the U.S. Air Force. For example, Huggins was the first to discuss the representation of auditory signals as the output of linear time varying (LTV) systems, a topic which received some discussion in our workshop. The workshop represented the tradition of Huggins, working towards novel mathematical representations of speech/audio signals, in line with current auditory theory.
