At its 70th meeting in Palma de Mallorca, Spain last month, the Motion Pictures Expert Group (MPEG) evaluated four competing technologies for the efficient coding of spatial audio. This technology has ...
MPEG-4 aacPlus / DTS Audio Transcoding System Proves Major Bandwidth Efficiency Can Be Achieved with Improvements in Perceived Audio Quality for 5.1 Discrete Multi-Channel Sound DTS, Inc. (NASDAQ:DTSI ...
MPEG-4 audio does not require a single or small set of highly efficient compression schemes but rather a complex toolbox to perform a wide range of operations from low-bit-rate speech coding to ...
Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...
SAN FRANCISCO—Last month's article discussed the theory behind high-end audio coding. The second half of this series will define broadcast quality and tandem coding losses, and look at their effect on ...
