Home Theater Network () The so-called next-generation audio format refers to the latest digital audio technology used in the film industry. Let's take a look at it in detail: Dolby TrueHD Dolby is the world's leading digital audio development organization, and its Dolby TrueHD is a lossless compression technology developed for HD disc media (a mandatory audio standard for HD DVD, an optional standard for Blu-ray, currently HD DVD has Fade out of the HD stage), the technical principle alone, in fact, is somewhat similar to the previous DVD-audio, but it can support up to 13.1 channels, the highest bit stream reaches 18Mbps, is a very BT audio stream (to With the HDMI interface, the traditional digital interface can't satisfy the transmission of this audio stream. The richness of information and the highest resolution studio master are the same, allowing users to enjoy high-definition images while enjoying the order. Amazing voice. Dolby TrueHD's LOGO Dolby TrueHD technology supports up to eight full-band lossless channels in Blu-ray format with a sampling rate of up to 192kHz, which can be used not only for 5.1 surround sound, but also for 7.1 surround sound (note that it is not a virtual Dolby 7.1). It is real 7.1). Dolby TrueHD is a lossless audio coding technology developed for HD disc media. Dolby TrueHD has the same amount of information and the highest resolution studio master tape Dolby TrueHD Audio Test Demo Dolby TrueHD features: * 100% lossless coding technology. * The code rate is up to 18Mbps. * Supports up to eight separate 24-bit/96kHz full-band channels. * Supported by High Definition Media Interface (HDMITM), a new single-line digital interface that combines audio and video. * Supports a variety of metadata features, including dialogue normalization and dynamic range control. DTS-HD Master Audio DTS (Digital Theatre System) is another very powerful digital audio format company in the United States. Currently, almost all 5.1 channel surround sound processors use DTS decoding technology, and there are more than 300 million consumer electronic products worldwide. DTS technology has been used and certified, and the influence and Dolby are among the best. In the field of high-definition audio, in addition to Dolby's Dolby TrueHD, the DTS HD format announced by DTS is also an important snobbery. DTS HD format The DTS-HD (High Definition) format has been used in next-generation digital cinemas and Blu-ray discs and HD DVD discs, supporting backward compatibility with DTS digital surround sound, DTS-ES, DTS96/24, with higher interchangeability and The expansion, sampling frequency and channel selection are also more flexible, but the compression ratio is still smaller than the Dolby Digital plus, the loss of sound information is less, and the details are more abundant. DTS-HD High Resolution Audio DTS-HD Master Audio is the most advanced audio format in the DTS standard. It is a true lossless compression encoding with a high variable bit rate of up to 24.5 Mbps (very horrible audio stream) on Blu-ray Disc. 7.1 independent channel, like Dolby TrueHD, can bring 96kHz/24bit digital surround sound effect consistent with the recording master, also requires HDMI interface transmission. DTS-HD Master Audio DTS-HD Master Audio up to 24.5Mbps on Blu-ray Disc 7.1 channel under the DTS-HD standard Dolby TrueHD and DTS-HD Master Audio are arguably the current high-definition audio formats, but decoding such a large audio stream requires a professional player and amplifier, as well as a dedicated HD interface.
