dts
What is a .dts file?
audio/vnd.dts
DTS is a framed perceptual audio bitstream used for multichannel cinema, disc, and media delivery. A stream carries sync words, frame headers, sample-rate and channel-mode information, and compressed audio blocks; byte order and padded variants mean a parser must inspect the bitstream rather than rely on the suffix.
How to use a .dts file
Use a short example .dts file to test sync detection, header metadata, channel and duration reporting, unsupported-profile behavior, and decoder failure without autoplay or an assumption that every browser can play the codec.
