DTS Sound Unbound
What it is
DTS Sound Unbound is a Windows app that provides access to DTS audio solutions, including DTS Headphone:X and a DTS:X decoder. Headphone:X uses Microsoft Spatial Sound to position game audio cues around, above, and below the listener. It works with any pair of headphones and offers custom tuning for a database of more than 500 headphones. The decoder plays DTS-encoded content stored locally or streamed to a device, and is available separately or bundled with Headphone:X. Audio technologies may require in-app purchases, although certain integrated headsets and PCs automatically license supported DTS features. The app can be installed on up to 10 devices. Its current focus for DTS-encoded content is headphones and multichannel speakers connected directly to a PC sound card. The FAQ describes availability on Xbox consoles and a free Home Theater upgrade on listed Xbox One and Series consoles.
