DTS-HD Master Audio

DTS-HD Master Audio is a combined lossless/lossy audio codec created by DTS (formerly Digital Theater Systems), commonly used for surround-sound movie soundtracks on Blu-ray Disc.

History

It is an extension of DTS' previous DTS Coherent Acoustics codec. Prior to 2004, it had been known as DTS++. Though DTS-HD Master Audio is an optional audio format for Blu-ray Disc format, by 2010, it had steadily become the standard for Blu-ray lossless audio format.

Features

One goal of the DTS-HD Master Audio format was to allow a bit-to-bit representation of the original movie's studio master soundtrack. To accomplish this, DTS-HD Master Audio supports variable bit rates up to 24.5 Mbit/s on a Blu-ray Disc and up to 18.0 Mbit/s for HD DVD. The format supports a maximum of 192 kHz sampling frequency and 24-bit depth samples from 2 to 5.1 channels, and 96 kHz/24bit resolution up to 7.1 channels. DTS-HD is capable of virtually any number of discrete channels but is limited by storage media.
