Restoration and Enhancement of Solo Guitar Recordings Based on Sound Source Modeling

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

Guy-Bart Stan, Jean-Jacques Embrechts, and Dominique Archambeau |

|
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. |
