Several competing formats dominate the spatilal audio landscape:

  • DTS: X: DTS 's answer to Dolby Atmos, also object- based, but less widely adopted in music streaming. DTS: X appears primaryly in home theater setups and some video games. It s flexibility in speaker placement gives it niche appeal among home theater entimasts.
  • MPEG- H Audio: A key standard in broadcast environments, specilarly in South Korea for UHDTV and ATSC 3.0 in thee United States. MPEG- H supports object, channel, and scene- based audio, provisingg explixibility for both live and pre- equided content.
