DTS is a private company that develops audio formats, similar to Dolby. The term "DTS" generally refers to DTS's digital surround audio technology that is used widely on DVD-Video discs, just like Dolby's Dolby Digital/AC3.
DTS differs from Dolby Digital in that it uses less compression and has a lower bass extension, which allows it to produce a better sound quality. DTS Stereo sounds almost identical to Dolby Surround.
DTS Coherent Acoustics is a perceptual audio codec. The main technique used is a QMF filter together with Huffman, ADPCM and vector quantization.
The DTS codec consists of a core and various extensions, that improve quality.
- Core: core components with core sub stream
- XCh: DTS-ES backward compatible 6.1 extension
- Adds an extra centre surround channel, with 6.1->5.1 downmix embedded in the core stream using default down-mix coefficients.
- X96: sampling frequency extension up to 96 kHz
- 48kHz downsampled stream is embedded in the core.
- XXCH: channel extension beyond 5.1
- Allows up to 32 additional channels, with the 5.1 downmix embedded in the core stream.
- XBR: Extended Bit Rate extension (>1.5Mbps)
- Guaranteed to be compatible with the DTS core
- XLL: Lossless extension
- core and residual signal are splitted.
- LBR: Low Bit Rate component
- DTS-Core: 5.1 Primary audio stream core component decoder
- Samples everywhere :)
- DTS-ES: Core + XCh, XXCh support
- DTS 96/24: Core + X96 Support (+ XBR?)
- DTS-HD High Resolution Audio: Core + XCh + XBR support
- DTS-HD Master Audio: Core + XLL support
