La première présentation du son multicanal DTS HD Master Audio en 7.1 à été le film 2046 en HD DVD lors du CES 2006.

DTS publicly demonstrated their new DTS-HD Master Audio technology for the first time at CES. Along with Dolby Digital, DTS is a mandatory audio component on both the Blu-Ray Disc (BD) and HD-DVD high definition disc formats though it is up to the content providers (e.g, the movie studios and record labels) as to whether they will include DTS-HD tracks on their content.
At its heart, DTS-HD Master Audio is an efficient audio codec (coder/decoder) that supports "nearly unlimited" discrete channels of high resolution audio, to accompany the video components of high definition discs. In practice, DTS-HD will most likely involve 7.1 channels when deployed on disc-based high definition content. DTS-HD features a lossless encoding option which means that the encoded audio signal can provide an exact match of the original studio recording with no compression artifacts, up to 24 bits of digital precision and 192 KHz sampling rates.
DTS demonstrated some DTS-HD content in their theater display and the results were definitely encouraging. The DTS folks played new movie and music tracks encoded in DTS-HD, with 7.1 channel lossless audio combined with 1080p "super high definition" video. Then they brought up the artists, engineers and producers involved in making these tracks for an interactive Q&A session. DTS CEO John Kirchner welcomed recording artist/producer Omar Hakim, performer/actor Ice T, musician/producer Martyn Ware and recording engineer Nathaniel Kunkel to the panel to discuss why each person was excited to be working in the multi-channel audio arena.
