Frequency-warped signal processing for audio applications

TLDR
A methodology, frequency-warped digital signal processing, is presented in a tutorial paper as a means to design or implement digital signal-processing algorithms directly in a way that is relevant for auditory perception.
Abstract
Modern audio techniques, such as audio coding and sound reproduction, emphasize the modeling of auditory perception as one of the cornerstones for system design. A methodology, frequency-warped digital signal processing, is presented in a tutorial paper as a means to design or implement digital signal-processing algorithms directly in a way that is relevant for auditory perception. Several audio applications are considered in which this approach shows advantages when used as a design or implementation tool or as a conceptual framework of design.

Discrete-time modelling of musical instruments

TL;DR: Physical modelling techniques that can be used for simulating musical instruments are described, including some nonlinear and time-varying models and new results on the digital waveguide modelling of a nonlinear string.

Comparison of features for musical instrument recognition

TL;DR: Several features were compared with regard to recognition performance in a musical instrument recognition system and the confusions made by the system were analysed and compared to results reported in a human perception experiment.

Principles of digital dynamic-range compression.

TL;DR: Of the various approaches that can be used to design a digital hearing aid, this paper considers broadband compression, multi-channel filter banks, a frequency-domain compressor using the FFT, the side-branch design that separates the filtering operation from the frequency analysis, and the frequency-warped version of the Sidebranch approach that modifies the analysis frequency spacing to more closely match auditory perception.

A cochlear frequency‐position function for several species—29 years later

TL;DR: It is shown that the newer extended data on human cadaver ears and from living animal preparations are quite well fit by the same basic function, which increases the function's value in plotting auditory data and in modeling concerned with speech and other bioacoustic signals.

System identification using Laguerre models

TL;DR: It is shown that the model order can be reduced, compared to ARX (FIR, AR) modeling, by using Laguerre models, and the numerical accuracy of the corresponding linear regression estimation problem is improved by a suitable choice of the LaguERre parameter.

Auditory filter shapes derived with noise stimuli

TL;DR: A wide‐band noise having a deep notch with sharp edges was used to mask a tone and the shape of the filter centered on the tone can be estimated from the first derivative of the curve relating tone threshold to the width of the notch in the noise.
