Dolby TrueHD is an advanced audio codec used in Blu-ray discs that supports up to 7.1 audio channels. It provides a high-quality sound experience with up to 16 discrete audio channels, each with a sampling rate of up to 192 kHz and a sampling depth of up to 24 bits. Unlike Dolby Atmos, TrueHD is a lossless technology, which means it delivers high-quality audio without any data compression, resulting in a sound quality that is identical to the studio master recording.
What is Dolby Atmos?
Dolby Atmos is a groundbreaking 3D surround sound technology that creates a lifelike audio experience. It allows sound to be placed anywhere in a 3D environment, making you feel like you’re part of the action. Dolby Atmos can be embedded in Dolby TrueHD (lossless) or Dolby Digital Plus (lossy). Although Dolby Atmos is not supported by any major streaming platform, it can be found on 4K Ultra HD Blu-ray discs, some video games, and select movie theaters.
How does Dolby TrueHD work?
The Dolby TrueHD specification can handle lossless data compression using Meridian Lossless Packing (MLP). This mechanism compresses the audio data without losing any quality and reduces the data size for easy storage or transmission. A Dolby TrueHD audio stream varies in bitrate, and it can support up to eight audio channels at 96 kHz/24 bits or six audio channels at 19.2 kHz/24 bits, with data transfer speeds of up to 18 Mbps.
