.CPT - DTS compact compressed audio stream
.DTS - DTS padded compressed audio stream
There is no built-in codec for this format. However if there is an installed Windows ACM codec that can decode it (e.g. the popular AC3Filter), then that can be used to decompress the data. It can also be copied in raw state to another file (using "Direct Stream Copy").
- DTS, mono / stereo / multi-channel.
