Dolby Atmos is a surround format that lets mixers place every sound in three-dimensional area, overhead included. On streaming companies, it rides inside Dolby Digital Plus, a lossy codec, so even an ideal setup will not match the lossless TrueHD monitor on a 4K Blu-ray. It additionally is not the identical factor as Netflix’s spatial audio, a separate headphone function.
