It can store up to 8 discrete channels of audio, for instance, a 7.1 surround sound, at up to 24-bit sample depth and 192 kHz sampling frequency but only up to 96 kHz sample frequency for 6.1 or 7.1 surround sound. The main application of DTS HD Master Audio is audio storage and playback for Blu-ray disc media. Due to the way DTS HD Master Audio is encoded, there is a lossy “core” for devices that cannot decode the more complex lossless audio, and playback the track in DTS, making this audio codec more flexible. Developed by DTS as a multi-channel and lossless audio codec. It is also known as DTS-HD MA or DTS++ but the latter has not been used for years.

Just to add in that Blu-ray players are able to do so as well but this is usually done at the receiver level. AVRs that can decode Dolby TrueHD can downmix a track from 7.1 to a 5.1 output, or a 5.1 to a stereo output. The compression mechanism used by Dolby TrueHD is Meridian Lossless Packing which is a lossless compression technique, used for compressing PCM audio data but with higher bit rates and more (when compared to DVD-Audio).ĭolby TrueHD tracks usually or may carry up to 8 discrete audio channels which are 7.1 surround sound of 24-bit audio at 96 kHz or up to 6 audio channels which are 5.1 surround sound at 192 kHz. Dolby TrueHD can go up to 16 discrete audio channels, a sampling rate of up to 192kHz, and a sample depth of up to 24 bits for each channel.

As the name suggests, it is developed by Dolby Laboratories, a lossless, multi-channel audio codec mainly used in Blu-ray discs as well as compatible hardware.
