Coding Technologies AB was a Swedish technology company that pioneered the use of Spectral Band Replication in Advanced Audio Coding. Its 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 their streams. [2] aacPlus with Parametric stereo, called Extended aacPlus, would become MPEG-4 HE-AACv2. Coding Technologies was acquired by Dolby Laboratories in 2007 for $250 million in cash. [3]
