Abstract

For audio communications over a lossy packet network, packet loss concealment techniques are needed. Multiple description coding (MDC) is a useful solution to this problem. This report describes an improvement of the MDC method for wideband audio streaming based on the sample splitting method in the time domain for a sound signal encoded by an MP3 encoder. We investigated the causes of deterioration associated with the conventional method. Using those findings, we propose a method to improve sound quality based on Wiener filtering and the use of a spectrum complement. Experiments were conducted to compare results obtained using the proposed method with those of the conventional method. Improvements of 0.12-1.65 in terms of Perceptual Evaluation of Audio Quality (PEAQ) were obtained over the conventional method.
