When it comes to sound, it doesn’t get much better than Blu-ray.  Or at least that’s what we thought before Dolby announced that they’re improving things even more.  They’re going to be using TrueHD technology along with 96K upsampling to provide the best audio possible for the home environment.  Dolby says that by improving the source of the lossless audio before encoding, they’re able to eliminate digital artifacts in the source material of 48K mastered recordings and restore the natural sound.

The real trick behind the 96K upsampling is an apodizing filter, which masks artifacts (known as pre-ringing) created during the content-creation process of films, television, and music.  This new TrueHD upsampling is fully compatible with all existing TrueHD enabled Blu-ray players and receivers, so there’s no need to worry about an upgrade.  The new Dolby process has already been implemented by several facilities and you should expect to see the improved audio in Blu-rays soon. Current titles with, or slated to have, the 96K Advanced Upsampling include the Christian Bale film 'The Flowers of War',  'San Francisco Symphony at 100', and the Joe Satriani concert film 'Satchurated: Live in Montreal'. Advanced 96K Upsampling releases will include special logo branding (pictured above).

Dolby has created a couple videos to help explain the situation: one on the 'San Francisco Symphony at 100' Blu-ray, and the other for 'Satchurated: Live in Montreal'. For and indepth crass course on Dolby TrueHD with Advanced 96K Upsampling, click here.
