The Discrete Fourier Transform (DFT) is a mathematical procedure that stands at the center
of the processing inside a digital signal processor. It has been widely known and argued in …

A method and apparatus for determining an auditory pattern associated with an audio
segment. An average intensity at each of a first plurality of detector locations on an auditory …

The measurement of perceived loudness is a difficult yet important task with a multitude of
applications such as loudness alignment of complex stimuli and loudness restoration for the …

A method includes the steps of calculating a power spectrum from an auditory stimulus,
filtering the power spectrum to obtain an effective power spectrum, calculating an intensity …

This thesis investigates the application of perceptual models to areas of audio engineering,
with a particular focus on music production. The goal was to establish efficient and practical …

Typically, speech enhancement algorithms minimize a suitable error criterion in the spectral
or time domain. Although the error criterions have included perceptual properties such as …

Sinusoidal models are widely used in parametric speech and audio coding schemes. A
common requirement in these applications is to select only a subset of components that …

Following the success in incorporating perceptual models in audio coding algorithms, their
application in other speech/audio processing systems is expanding. In general, all …

Audio signal modeling and simulation is important in several coding, noise removal, and
recognition applications. This paper focuses on implementing models for loudness …

The processing power and storage capacity of portable devices have improved considerably
over the past decade. This has motivated the implementation of sophisticated audio and …
