DTS-HD Master Audio

<p>DTS-HD Master Audio (DTS-HD MA; known as DTS++ before 2004) is a <a href="/facts/Surround_sound/9FXUKVvs">multi-channel</a>, <a href="/facts/Lossless_data_compression/LS702KsN">lossless</a> audio <a href="/facts/Codec/C7b7Am8t">codec</a> developed by <a href="/facts/DTS_(sound_system)/wbQwqtdQ">DTS</a> as an extension of the <a href="/facts/Lossy_compression/jHW7DDv3">lossy</a> <a href="/facts/DTS_(sound_system)/wbQwqtdQ">DTS Coherent Acoustics</a> codec (DTS CA; usually itself referred to as just DTS). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then stores a concurrent stream of supplementary data representing whatever the DTS encoder discarded. This gives DTS-HD MA a lossy "core" able to be played back by devices that cannot decode the more complex lossless audio. DTS-HD MA's primary application is audio storage and playback for <a href="/facts/Blu-ray/zyPalhfG">Blu-ray</a> media; it competes in this respect with <a href="/facts/Dolby_TrueHD/ySxj3zIY">Dolby TrueHD</a>, another lossless surround format.
