Coding Technologies AB was a Swedish technology company that pioneered the use of spectral band replication in Advanced Audio Coding. It is a major provider of audio compression technologies for digital broadcasting. [3]
The company was founded in Stockholm, Sweden, in 1997 by Lars Liljeryd. [4] A German subsidiary was formed in 2000 as Coding Technologies GmbH (later renamed Dolby Germany GmbH) with support from the research organization Fraunhofer IIS. [1] The company also had offices in the United States and China.
Coding Technologies was acquired by Dolby Laboratories in 2007 for $250 million in cash. [5] Since then it was renamed to Dolby International AB.
Coding Technologies’ MPEG-2 AAC-derived codec, called aacPlus, was published in 2001 and submitted to the MPEG for standardization. The codec would become the MPEG-4 High-Efficiency AAC (HE-AAC) profile in 2003. XM Satellite Radio used aacPlus for its streams. [6] aacPlus with Parametric stereo, called enhanced aacPlus, would become MPEG-4 HE-AACv2. The technology was adopted by Qualcomm in 2004, allowing it to be integrated into wireless handsets. [7]
Lars Liljeryd, Kristofer Kjörling, and Martin Dietz received the IEEE Masaru Ibuka Consumer Electronics Award in 2013 for their work at Coding Technologies, developing and marketing SBR-based audio coding. [2] [8]
