Dolby Atmos on streaming will finally sound as good as 4K Blu-ray, based on these blind test results of audio engineers — but this still won’t cause collectors to switch from physical media
Dolby Atmos streaming audio may soon match the quality of 4K Blu-ray thanks to a new codec called Dolby AC-4. Audio engineers have conducted blind tests indicating that this codec delivers superior sound quality without high bandwidth requirements. However, despite these advancements, collectors are unlikely to abandon physical media for streaming options.
- ▪Dolby AC-4 is a new codec designed to improve audio quality for streaming.
- ▪Audio experts have found that Dolby AC-4 sounds comparable to uncompressed Blu-ray audio.
- ▪Current streaming services primarily use the DD+JOC codec, which has limitations in sound quality.
