Dolby says their upsampling and filter process will also clean up artifacts like preringing.
You may have guessed, but here on High-Def Digest, we like our Blu-rays. All that video and audio quality packed onto a tiny disc is a pretty sweet setup, and it's about to get sweeter, thanks to the folks over at Dolby.
The company has created a new upsampling technique that allows for even better sound from your Blu-ray discs. Dolby accomplishes this by taking the upsampling that's often done by ultra-high end products and instead baking that into the disc from the beginning. By improving the audio before encoding, Dolby says that it's passing on the best possible sound on to users and minimizing the effect of artifacts along the way.
If you have a Blu-ray player or Receiver that's compatible with Dolby TrueHD, you won't have to do a thing to enjoy the new tech – no new hardware or software is required.
Dolby says that several authoring houses and other facilities are already on board including Deluxe Digital Studios and Technicolor.
