The Design of Encoding Functions for Stereophonic and Polyphonic Sound Systems
M. Poletti p. 948
Encoding functions for ambisonic, stereophonic, and polyphonic sound reproduction systems can be designed for recordings made with elementary coincident microphones. Strong emphasis is placed on holographic reproduction systems that attempt to reproduce the original sound field in a region around the listener's head.

Compensation for Nonlinear Distortion of Horn Loudspeakers by Digital Signal Processing
Wolfgang Klippel p. 964
Horn loudspeaker nonlinear distortion can be compensated by prefiltering the electrical input inversely from the results of nonlinear loudspeaker modeling using static nonlinear and dynamic linear subsystems. This method requires less computational effort and memory than other generic architectures. When using simplified versions of this filter, the performance of a professional horn loudspeaker was shown to be substantially improved by compensating only for nonlinear wave steepening.

Multichannel Signal Processing Techniques in the Reproduction of Sound
P. A. Nelson, F. Orduña-Bustamante, and H. Hamada p. 973
A general approach to the design of inverse filters for multichannel sound reproduction systems is shown using algorithms that enable the rapid adaptation of inverse filters in response to the reproduced sound field. Experimental results and computer simulations illustrate the potential to manipulate stereophonic images to improve existing recordings.

Experiments on a System for the Synthesis of Virtual Acoustic Sources
P. A. Nelson, F. Orduña-Bustamante, D. Engler, and H. Hamada p. 990
Experiments are presented showing the subjective evaluation of a digital signal processing system designed to produce virtual acoustic sources at the listener's ears irrespective of the immediate sound reproduction environment. Several widely different environments are evaluated, with emphasis on the accuracy of localized images to the front, sides, and rear of the listener.
