Dolby Digital Plus Audio Coding Dolby® Digital Plus is an advanced, more capable digital audio codec based on the Dolby Digital (AC-3) system that was introduced first for use on 35 mm theatrical films and then chosen for consumer formats that include DVD, cable, satellite, and digital broadcast television. Today Dolby Digital Plus NeuralX puts some of the soundtrack in the ceiling speakers. Dolby surround does not. In war for the planet of the apes, there's a scene with an avalanche. There are trees snapping, and snow flowing. Dolby surround was subtle in that the overhead speakers included sounds of trees snapping, and wind blowing. WithAtmos active and 4 (or 6) height speakers it circles at the ceiling, all lower channels are silent. With just two height speakers the helicopter moves forth an back from side to side. without Atmos (or Atmos forced switched off due to a 5.1 system) the helicopter circles through the lower speakers. DolbyDigital Plus (E-AC-3) is an improvement over AC-3 capable of supporting 7.1 surround sound. It supports the same sample rates - 32, 44.1, and 48 kHz - as AC-3. It supports higher bit rates and provides better quality at lower bit rates than AC-3. All E-AC-3 decoders can decode AC-3 streams. Thestereo separation would most likely be due to the DSP, as you were told. But, why stereo sounds better than Dolby Digital would possibly be due to the movie itself, the settings of the movie sound, or the sound of the HTiB. First, the movie may have only been recorded in stereo, even older movies were in mono. GVa1.
