A novel concept for perceptual audio coding is presented which is based on the addition of a pre- and post-filter controlled by a psychoacoustic model to a transform coding scheme.
We study the application of parametric piecewise modeling (PPM), a novel coding technique, for audio coding. PPM is based on either the polynomial, Bezier or Chebyshev parametric representation.
I N connection with a study of communication problems, observations of submarine cable interference were made over periods totaling about 20 months during the years 1928 to 1931.
The auditory sense is an intuitive and immersive channel to experience our surroundings, which motivates us to augment our perception of the real world with digital auditory content.
This paper describes an infrastructure that supports data transforms and transmissions as part of multimedia communications.
Anxiety, stress and depressive mood are frequent mental symptoms in humans before surgery. These factors and surgery itself can affect cognitive functions.
Very little information is available about the processing principles that are used by the brain stem auditory nuclei and by the auditory cortex.
We describe here a computational model based upon the temporal characteristics of the information in the auditory nerve fiber firing patterns.
A fundamental component in every speech recognition system is its front-end. Most of the existing front-ends are based on variations of Fourier analysis.
This paper presents a new approach to an auditory model for robust speech recognition in noisy environments.
