Special Issue on Digital Audio Signal Processing For Multimedia Communications and Broadcasting


Renewed interest in digital processing of audio signals has been stimulated by the introduction of multimedia communication via the Internet and digital broadcasting systems. These new applications demand high bandwidth and require innovative solutions to an old problem: how to achieve high quality at low bit-rates. While modern psycho-acoustic theories are shedding new light on the assessment of audio quality -- many issues are still open. Sophisticated time-frequency representations of signals have been introduced to increase flexibility and performance in coding. However, their use in audio coding is still at an early stage. The definition of suitable audio representations must be adapted to both models of sound and perception. Furthermore, the effect of quantization and the efficient quantization techniques must be carefully studied. Structured audio coding is another emerging paradigm for high quality music broadcasting. In structured coding, algorithms and synthesis parameters are transmitted rather than just encoded sound samples. While synthesis algorithms have been developed for many years, there is a great demand for procedures that automatically allocate synthesis resources and extract synthesis parameters, i.e., fully automated structured coding. Other important issues include the development of new types of techniques for digital audio effects, realistic sound spatialization, sound restoration and processing for multimedia electroacoustic transducers. Today's digital audio algorithms draw ideas from recent and past experience in synthesis and processing of music and speech signals, perceptual and physical models of sound and hearing, transform coding and information theory. The key to success is to link several aspects of this multidisciplinary field together to develop new techniques or to improve existing methodologies. These new goals can strongly impact classical audio processing tools.

The aim of this special issue is to present state-of-the-art signal processing algorithms and methods for digital audio signal processing in the context of broadcasting, either via radio or the Internet. Prospective papers should be unpublished and present solid research work offering innovative contributions either from a theoretical or application point of view.
