Coherent Acoustics
Coherent Acoustics is a sound format based on the DTS standard. It is used on some DVDs, CDDAs and in wave files. It is a high quality codec, which unlike the cinema DTS standard does not require separate DTS CD-ROM media and hardware decoders.
The 'DTS Coherent Acoustics' codec (what 'DTS' commonly refers to) was born out of the need for a consumer grade compression scheme. This sound format uses 4:1 compression and is based on the APTX100 decoder.
An Open Source DTS decoder called is part of the VideoLAN project.
The DTS Coherent Acoustics standard (ETSI 102 114 v1.2.1), is published by the ETSI and available (look for DTS Coherent Acoustics).
