Coding Technologies

from Wikipedia, the free encyclopedia

Coding Technologies AB (formerly Coding Technologies Sweden AB ) was a privately owned Swedish IT company. It was founded by Lars Liljeryd in 1997 in a basement on Sveavägen in Stockholm and had offices in Germany ( Nuremberg ), the People's Republic of China and the United States . In 2007 it was acquired by Dolby Laboratories for around $ 250 million. The company's best- known products were spectral band replication (SBR) and (together with Philips ) parametric stereo (PS), on which it held and marketed patents. These techniques are now combined with MPEG-4 Audio AAC to improve the subjectively perceived audio quality at the lowest bit rates and standardized as HE-AAC in widespread use. Coding Technologies also held the trademark rights to the name "aacPlus", used synonymously with HE-AAC, and marketed it, as well as " mp3PRO " (MP3 + SBR) before that .
