Every detail of the original recording is preserved because Dolby TrueHD reproduces audio bit-for-bit identical to the studio master.ĭolby TrueHD accomplishes this using a suite of highly sophisticated compression technologies. These enable 100 percent lossless audio in files half the size of uncompressed pulse-code modulation (PCM). What this means for you is the best possible sound from Blu-ray Discs™ and streamed or downloaded sources.

Most movie and TV soundtracks are recorded at 48k. Unfortunately, the 48k recording process can introduce an unnatural harshness or edginess to the sound during the conversion from analog to digital. Dolby TrueHD corrects this problem by applying higher sample rates and increased playback quality through an advanced apodizing filter. On Blu-ray, Dolby TrueHD supports up to eight full-range channels of 96 kHz/24-bit audio and six full-range channels of 192 kHz/24-bit audio. It also features advanced 96k upsampling to produce the highest-quality Blu-ray audio from material originally recorded at 48k. Transfers data at bit rates of up to 18 Mbps for unmatched sound quality.ĭolby TrueHD lossless audio advanced features The result: you experience entertainment as it was meant to be heard.Delivers up to 16 channels of pristine audio at studio-master quality.Maintains consistent dialogue levels when changing between Dolby TrueHD and Dolby Digital programming.Includes dynamic range control, enabling reduced peak volume levels without loss of overall sound quality - ideal for listening without disturbing others.Provides superior 7.1 downmix overload detection and protection.Gives the Blu-ray content creator the ability to include a companion Dolby Digital (640 kbps) 5.1-channel theatrical mix on 7.1-channel Dolby TrueHD titles.
