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.
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.
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
examples have practical applications in music recording and mastering, surround
processing, microphone arrays, noise reduction, speech processing, hearing
aids, and forensics.
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.
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.
