February Meeting Notice

 

February 2006 Meeting Notice

 Subject: Auditory Scene Analysis and Audio Signal Processing Applications
 Speaker:

Brett Crockett, Dolby Laboratories

 Place: Dolby Labs, San Francisco
 Time and Date: Feb 21st, 7:30 PM (refreshments at 7:00 PM)

Auditory Scene Analysis (ASA) addresses the central problem of audition, or how the brain deals with mixtures of sounds. The sensory components that arise from distinct environmental events are segregated into separate perceptual representations. The separation of a sound signal into components that correspond to the different sound sources is a fundamental task of the auditory system. By performing an auditory scene analysis on audio signals, the auditory event boundaries, which may exist in both the frequency and temporal or time domain and between channels, can be identified and the audio processed accordingly.

This talk will present a brief overview of auditory scene analysis including an overview of methods to perform the analysis for use in audio signal processing. In addition, methods for using auditory scene analysis of audio signals in conjunction with high quality multi-channel time scaling and pitch shifting, improved transient pre-noise performance of low bit rate audio coders and audio identification will also be presented.
