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.
Dolby TrueHD corrects this problem by applying higher sample rates and increased playback quality through an advanced apodizing filter.
Unfortunately, the 48k recording process can introduce an unnatural harshness or edginess to the sound during the conversion from analog to digital. Most movie and TV soundtracks are recorded at 48k. What this means for you is the best possible sound from Blu-ray Discs™ and streamed or downloaded sources. These enable 100 percent lossless audio in files half the size of uncompressed pulse-code modulation (PCM). 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. Dolby TrueHD ensures that what you hear at home is completely accurate to the artist's vision - not an approximation or a recreation, but the full audio experience. A filmmaker can spend years working to make every detail of a movie perfect, and this includes the audio.
