Background

The company was founded in Stockholm, Sweden, in 1997 by Lars Liljeryd.{{Cite web |last=Office |first=European Patent |title=Lars Liljeryd (Sweden) |url=https://www.epo.org/news-events/events/european-inventor/finalists/2017/liljeryd.html |access-date=2023-04-04 |website=www.epo.org |language=en}} A German subsidiary was formed in 2000 as Coding Technologies GmbH (later renamed Dolby Germany GmbH) with support from the research organization Fraunhofer IIS. 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.{{cite web |date=8 November 2007 |title=Dolby Laboratories to Acquire Coding Technologies |url=http://investor.dolby.com/releasedetail.cfm?releaseid=274917 |url-status=dead |archive-url=https://web.archive.org/web/20100612124445/http://investor.dolby.com/ReleaseDetail.cfm?ReleaseID=274917 |archive-date=12 June 2010 |accessdate=25 May 2015}} Since then it was renamed to Dolby International AB.

Technologies

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.{{cite web|title=XM Drops PAC for CT-aacPlus|url=http://www.radiomagonline.com/industry/0003/xm-drops-pac-for-ctaacplus/26254|publisher=Radio|accessdate=25 May 2015|date=14 May 2002|archive-url=https://web.archive.org/web/20150526031908/http://www.radiomagonline.com/industry/0003/xm-drops-pac-for-ctaacplus/26254|archive-date=26 May 2015|url-status=dead}} 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.{{Cite web |last=RadioWorld |date=2004-03-22 |title=Qualcomm Chooses Coding Technologies' aacPlus |url=https://www.radioworld.com/news-and-business/qualcomm-chooses-coding-technologies39-aacplus |access-date=2023-04-04 |website=Radio World |language=en-US}}
