| Restoration and Enhancement of Solo Guitar Recordings Based on Sound Source Modeling (PDF-220K) | |
| Paulo A. A. Esquef, Vesa Välimäki, and Matti Karjalainen | 227 |
| By combining techniques for music synthesis and analysis, the authors demonstrated that the restoration of guitar recordings had been corrupted by added noise and limited spectral bandwidth. During the analysis phase the parameters of the synthesis model were extracted and then used to define the synthesis model, which is able to produce a simulation without noise or spectral limits. The initial corruption and the musical complexity limit the accuracy of the parameter extraction. The results of this work should be considered a pilot study. | |
| On the Quality of Hearing One's Own Voice (PDF-164K) | |
| Ronald Appel and John G. Beerends | 237 |
| Evaluating the quality of sound reproduction in a telecommunications environment over long distances is unique and unrelated to the classical problem of reproduction quality. Specifically, the experiments attempt to calibrate the acceptable quality level for the listener's own voice through the side channel when it has been delayed and distorted. The proposed model represents degradation as a single number to predict the subjective experience of comfort while talking and listening to one's own voice. | |
| Comparison of Different Impulse Response Measurement Techniques (PDF-264K) | |
| Guy-Bart Stan, Jean-Jacques Embrechts, and Dominique Archambeau | 249 |
| Although the impulse response of a linear, time-invariant system is mathematically defined, the choice of empirical methods strongly influences the results when applied to a real room with noise and other imperfections. The authors explored the relationship between the environment under test and four different approaches: maximum-length sequences, inverse repeated sequences, time-stretched pulses, and SineSweep. Recommended choices are suggested based on noise level, accuracy, and calibration effort. | |

| Variability in the Headphone-to-Ear-Canal Transfer Function (PDF-48K) | |
| Ken I. McAnally and Russell L. Martin | 263 |
| The quality of virtual auditory space simulation using headphones is determined, in part, by the accuracy of the head-related transfer function that models the influence of the head and pinna as a function of sound location. A potential problem with the resulting filters is that the transfer function is influenced by the variability of listener headphone placement, which might change the localization accuracy. After careful study the authors concluded that the variability is not sufficient to significantly influence perception. | |
