Dolby ups TrueHD lossless audio on Blu-ray to 96k, says every upsampled bit is amazing (video)
Just because your home theater can handle lossless audio doesn't mean the sound is as good as it could be. Dolby is now giving Blu-ray producers using Dolby Media Producer Encoder v2 the choice of premastering TrueHD surround sound at an upsampled 96k. Along with just squeezing the most possible clarity and depth out of 48kHz audio, the encoding purportedly eliminates some of the harshness of digital sound through an apodizing (signal altering) filter. At least three projects have already been given the 96k treatment, and authoring firms like Technicolor have upgrades in place to give that noticeable boost to your next Blu-ray movie.
Cambridge Audio intros DacMagic upsampling digital-to-analog converter
You've got to love the Brits, don't you? According to Cambridge Audio, this is a "digital to analogue converter," which we can't help but read aloud with a charming accent. At any rate, the same company who just announced its plans to enter the Blu-ray realm is also looking out for its primary crowd: the audiophiles. The October-bound DacMagic upsampling DAC is billed as a relatively affordable way to upgrade any PC, network music device, gaming console, etc. to "truly high-end sound quality." The £199.95 ($353) device boasts a variety of connections including S/PDIF, Toslink and USB along with "Adapted Time Filtering (ATF) upsampling technology developed in conjunction with Anagram Technologies of Switzerland which converts 16-24 bit audio data to 24 bit/192kHz."
