The latest audio solution from Dolby Labs attempts to bring the Dolby experience to broadcast, mobile, PC and online mediums through the MPEG-4 HE-AAC open-standard audio codec. The sound geeks combined the advance bit-rate efficiencies of the codec with the goodies of Dolby audio. Think of 5.1 audio sound but at a lower bit-rate that mobile and broadcast platforms could support. Pulse can carry all the metadata found in other Dolby codecs, just in a more efficient, bandwidth-saving way. Expect to see Pulse applications in 2009.
