Dolby is aiming to take back its market share of Blu-ray audio soundtracks by adding a new phase in the Blu-ray authoring process.
The company is adding the option of upsampling native 48kHz audio to 96kHz in a pre-filter process to the Dolby TrueHD encoding process.
The new technology is based on the Meridian apodising filter employed in their highest level of Compact Disc player.
The filter effectively identifies the pre-ringing created by brick wall audio filters and works to mask that effect.
The technology provides a clearer sound field and crisper transients compared to traditional upsampling technologies.
The best part is that this technology is being offered to content providers and will be fully compatible with the current Blu-ray players and home theater systems.
Dolby will have this technology installed at authoring houses including Technicolor and Deluxe Digital Studios, so little stands in the way for content providers to offer this technology.
This technology will be exclusive to Dolby TrueHD Blu-ray releases.
It will be interesting to see how rapidly this technology is employed – watch for the Advanced 96k Upsampling badge on future releases!
