Frequency-Warped Signal Processing for Audio Applications
Aki HArmA, Matti Karjalainen, Lauri Savioja, Vesa VAlimAki, Unto K. Laine, and Jyri Huopaniemi 1011

A digital signal processing method is presented, which is applicable to human auditory perception. It is an effective means to design or implement digital signal processing (DSP) algorithms directly. The human auditory system is complex, nonlinear, time variant, and adaptive. Therefore, models of auditory perception are also complex. This paper demonstrates that a warped DSP system can be designed to approximate accurately the frequency resolution of the human auditory system.

Auditory Models for Gifted Listeners
Seymour Shlien 1032

Little is known about gifted listeners, some of whom are remarkably sensitive to codec quantization noise. Training appears to be an important aspect in the development of these abilities. This study indicates that sensitivity to codec quantization noise is likely governed by psychoacoustic efficiency rather than unique frequency selectivity.

Recurrent Neural-Network-Based Physical Model for the Chin and Other Plucked-String Instruments
Sheng-Fu Liang and Alvin W. Y. Su 1045

A traditional Chinese plucked-string instrument, the chin, is chosen to demonstrate the use of neural networks to determine suitable synthesis parameters. The structure of the network is designed for analysis of plucked-string instruments and its corresponding synthesis engine. This is a general method that can be used to synthesize any plucked-string musical instrument.

Aliasing in Digital Clippers and Compressors
Paul Kraght 1060

Digital signal limiters and dynamic-range compressors generate aliasing products as an undesirable side effect that can be clearly audible. Reduced aliasing can be achieved by soft limiting, at the expense of reduced overall dynamic range. A second or higher order detector can be used to effectively eliminate aliasing in digital signal processing systems.
