Even if you keep the whole track, you will only listen to the Core, so just keep that and remove the HD audio. If you decode through your PC or you passthrough to a decoder that doesn't support DTS-HD you don't need both streams.If you have bought a software decoder or have a decoder that supports DTS-HD and you pass-through the audio through HDMI or Optical, just create an mkv file and maintain the original audio track from the Blu-ray.Now since there are only a few software decoders for DTS-HD and these at insane prices we can pretty much assume the following scenarios: What do you need to ripįirst of all I assume you have at least a 5.1 sound system, otherwise you should just downmix to stereo. The advantages of this format are backwards compatibility with older decoders, smaller size of the audio track than using both an HD and a Core track and faster encoding. In decoders that support DTS-HD, both the streams are being played in the same time giving you lossless original sound quality. That way in older decoders that only support the old DTS format, you just listen to the Core stream. Then both streams are used to create the final DTS-HD MA track. Then the Core is compared to the original audio and any parts found missing are being added an an extra "residual" stream. The DTS-HD Core and how the whole format worksĪs you can read in detail in the DTS-HD white paper the encoding process of a DTS-HD track in simple terms is the following: first the Core, which is lossy format, similar to the old DTS is being created. That is why we will try to explain how it works, and of course, how you can rip it, in this article. An example of a lossy audio format is MP3, while another lossless audio format is FLAC.ĭTS-HD has pretty much become the standard audio track of most Blu-ray discs. If you are unaware with the lossless term, it is a compression method that allows you to have the exact original data from the compressed data after extraction, in contrast to lossy formats which only allows an approximation of the original data to be reconstructed. It replaces the old DTS audio (actually it extends it) and its main goal is to allow a bit-to-bit representation of the original movie's studio master soundtrack. DTS-HD Master Audio or just DTS-HD in many descriptions is a lossless audio codec by Digital Theater System. ![]()
