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.
Codec info
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.
DTS Extensions
- Core: core components with core sub stream
- XCh: DTS-ES backward compatible 6.1 extension within core sub stream
- X96: sampling frequency extension up to 96 kHz within core sub stream
- XXCH: channel extension beyond 5.1 within core sub stream
- ExSSCore: Core component within extension sub stream
- ExSSXBR: constant bit rate extension (>1.5Mbps) within extension sub stream
- ExSSXXCh: XXCh within extension sub stream
- ExSSX96: X96 within extension sub stream
- ExSSLBR: Low Bit Rate component within current extension sub stream
- ExSSXLL: Lossless extension within the extension sub stream
DTS Products
- DTS-Core: 5.1 Primary audio stream core component decoder
- DTS-ES: Core + XCh, XXCh support
- DTS 96/24: Core + X96 Support
- DTS LBR: ExSSLBR support
- DTS-HD High Resolution: Core + ExSSXBR support
- DTS-HD Master Audio: ExSSXLL support
- DTS-Broadcast, DTS Neo, DTS- Surround Sensation: unknown
