We missed this one last week: Dolby Laboratories has bought Coding Technologies AB, a privately held Swedish developer of audio compression technology, for $250 million in cash. Coding is heavily focused on the mobile music compression, and its clients include SK Telecom, (NYSE: SKM) Nokia (NYSE: NOK) and RealNetworks. Dolby said 80 percent of CT’s revenues come from the mobile market, the balance from the Internet, reports TechConfidential. Coding was backed by Swedish venture capital firm VC Cimon as well as private and industrial investment.

EETimes: Coding Technologies with an R&D center in Nuremberg, Germany, as well as subsidiaries in China and the USA has developed several de-facto standards for audio data compression, including the aacPlus codec which is part of the MPEG-4 standard and MP3pro, a refinement of the MP3 standard. aacPlus is also used in Digital Radio Mondiale (DRM), a technology that aims at innovating AM band broadcast reception.
