DTSäänet

DTSäänet is a term used in Finnish to refer to the DTS family of surround sound formats developed by DTS, Inc. and used to encode multichannel audio for film, television, and video games. It denotes the set of technologies that deliver immersive audio tracks on various media and playback systems.

DTS formats are found on Blu-ray discs, some streaming services, and game consoles. DTS, Inc. is an American company that has produced these formats since the 1990s, with the aim of providing high-quality multichannel sound across different devices and platforms.

Core formats include DTS Digital Surround (5.1/7.1). DTS-HD Master Audio provides lossless audio on Blu-ray; DTS-HD High Resolution is a high-bitrate lossy variant. Object-based formats include DTS:X and its advanced version DTS:X Pro. There is also DTS Neural:X for upmixing to 7.1.4 on various playback systems and DTS Headphone:X for headphone virtualization.

DTS competes with Dolby Digital and other surround formats; both are widely used in home entertainment. Playback requires a device or receiver with a licensed DTS decoder, and many modern receivers support both DTS and Dolby formats, allowing users to choose or automatically select the best option depending on the source.
