Dereverberation and Other Audio Trickery by Dr Gilbert Soulodre, FAES

Tues. May 14, 7pm, Devlin Hall – Room 026 Boston College

There are many difficult audio signal processing problems that remain unresolved to a satisfactory and practical level. Examples of this include, dereverberation, sound source separation, and signal reconstruction. By using a perceptually-motivated approach to audio signal processing, many of these difficulties can be largely overcome, enabling new algorithms to be derived. This processing approach has been used by the author to create a wide variety of audio products. The talk will outline the general processing approach and will then use the dereverberation problem as a detailed example. Numerous other audio processing examples based on decomposing audio signals into perceptual “streams” will be provided. The examples have practical applications in music recording and mastering, surround processing, microphone arrays, noise reduction, speech processing, hearing aids, and forensics.

Dr. Gil Soulodre has over 30 years experience in the audio field, both as a mixing engineer and a researcher. He is a prolific writer of scientific papers in the areas of concert hall acoustics, auditory perception, subjective testing, DSP processing, and multi-channel audio. He has invented a wide variety of audio processing algorithms and authored more than 30 patents. Through his company Camden Labs, his development efforts include products in the areas of telecom, military communications, the music recording industry, microphone processing, hearing aids, music compression, and automotive audio. Dr. Soulodre is a Fellow of the AES and has received recognition and awards from the Acoustical Society of America, the American Institute of Physics, the IEEE, and the Canadian Government. In 2006 he received the AES Publications Award. Most recently the National Academy of Television Arts and Sciences awarded Dr. Soulodre with a 2011 Emmy Award for Technical and Engineering Achievement.


FROM POINTS NORTH AND SOUTH: Take Interstate 95 (Route 128) to Exit 24 (Route 30). Proceed east on Route 30, also known as Commonwealth Avenue, and follow for about five miles to Boston College.

FROM POINTS WEST: Take the Massachusetts Turnpike (Route 90) to Exit 17. At the first set of lights after the exit ramp, take a right onto Centre Street. Follow Centre Street to the fourth set of lights, and turn left onto Commonwealth Avenue. Follow Commonwealth Avenue 1-1/2 miles to Boston College.

Devlin Hall is located in the center of the Chestnut Hill Campus. Parking is available in the Commonwealth Ave Garage for a minimal price. The entrance for Room 026 is in the rear of Devlin hall.
