What is DTS Play-Fi?

DTS Play-Fi is a premium wireless audio ecosystem for whole-home music, whole-home TV audio, and app-based private listening, supporting high-resolution audio streaming and sub-millisecond playback accuracy. Compatible products, including TVs, mobile devices, sound bars, receivers and speakers seamlessly interoperate to form a complete whole-home entertainment experience.

About Critical Listening Mode

Play-Fi traditionally plays music streams in their native format and encoding. Hi-Res Audio, however, is down-sampled to CD quality to maintain compatibility across all products within the ecosystem. When using Critical Listening Mode with supported products, Hi-Res Audio, up to 192 kHz/24-bit resolution, is streamed without down-sampling or re-sampling, delivering bit-perfect audio with full signal integrity, completely free of network induced jitter.
