The Analog Devices Dolby Digital decoder algorithm features down-mixing to match the number of loudspeakers at the listerner's site to the number of channels encoded, enabling users to play Dolby Digital encoded audio on their current speaker system, and upgrade later. The algorithm also provides dialog normalization which enables audio from all sources to be reproduced at the same subjective loudness, avoiding changes in audio levels from different sources. Dynamic range control features allow users to vary compression values, adjusting the dynamic range in accordance with the source material and personal listening preferences. The decoder supports sampling frequencies of 32, 44.1 and 48 KHz. This allows a natural upgrade path to multiprocessing applications, including medical image processing, 3D graphics, and radar and sonar equipment.
Designers can double the performance of their products while preserving their sofware investment.
This is largely attributed to the industry's broadest portfolio of products, hundreds of third party hardware and software systems, and defacto standard for real-time multiprocessing. Inc. All rights reserved.
