Tech: Dolby Introduces 96k Upsampling to Improve Blu-Ray Audio

Don’t you just love the technological age we live in? Video games have never looked better, televisions are constantly improving and the sound. Oh boy the sound.

Well that sound is just about to become even better than traditional lossless audio tracks currently on Blu-Ray discs. Dolby introduced a new system this week at Dolby’s Fidelity Forum 2.0 called “Dolby TrueHD Advanced 96k Upsampling”.

I’ll give you a second to mop up the drool before you find out what it means.

Basically, as it stands today, the audio on most of the Blu-Ray discs is sampled at 48kHz. This is not really a bad thing, especially since movie tracks are recorded at 48kHZ at the studio level. The problem is that once that soundtrack is moved onto the disc, there isn’t a lot of wiggle room.

“Lossless audio is a key distinguishing feature of Blu-ray content.” The press release explains.

“All things being equal, you cannot improve on the quality of lossless audio coding; however, you can improve on the quality of the source PCM content prior to lossless encoding, and this is precisely what we have achieved with our advanced 96k upsampling technology

“Studios and authoring facilities that implement Dolby TrueHD with advanced 96k upsampling can elevate the quality of PCM audio prior to lossless Dolby TrueHD encoding, ensuring that consumers get the very best audio performance possible from their Blu-ray playback systems.”

The great news is that this technology will already work with your Blu-Ray player and most AV Receivers. Dolby said that many studios have already upgraded their equipment to impliment the new tech, so movies in the not-too-distant future should start taking advantage of it.
