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 was called aacPlus, and was submitted to MPEG for standardization. The codec would become the MPEG-4 HE-AAC profile. XM Radio used aacPlus for their streams. 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.[1]
