So, if I can downmix to 5.1 and compress truehd to eac3, how do I do that? Handbrake doesnt seem to offer it, and staxrip which I am working with at the moment also doesnt seem to have it.SurCode for Dolby Digital Plus Bundle for AVID Overview Currently working on figuring out the best way to rip my 4k uhd blu rays, and those I am keeping the lossless audio. Would really like to use eac3 and keep 7.1, oh well. though maybe thats just the way it has to be. And it just seems silly to have 5gb of video and 5gb of audio. Just that the first rip I tried to keep the trueHD doubled the size of my rip. I probably cant hear too much of a difference, but I just got a whole new setup (4k tv, denon 1400, 7.1 speakers) and I would like to use them as much as possible. Most of my blu ray rips I just take whatever master audio track and go to 5.1, and 640kbps AC3. I have seen that there are some other audio codecs that could potentially keep the 7.1 tracks but I am hesitant to try it. I just need to find a way to compress TrueHD audio while retaining the Atmos metadata. Atmos should be compatible with TrueHD and EAC3. I think you're misunderstanding my ask here. Maybe you need an atmos stream to carry the metadata along, and old AC3, designed to go through spdif, makes them useless. I get the benefits of Atmos directional audio while saving a ton of hard drive space and still getting very high audio quality. This is why I want to compress TrueHD to DD+ while retaining the Atmos metadata. My ears are not well trained enough to hear the difference between TrueHD and DD+, and I don't have top tier equipment either. It is a major step forward without consuming too much hard drive space.ĭolby TrueHD is lossless audio. It is roughly on par with MP3.ĭolby Digital Plus is also lossy audio, but is much more modern and double the quality of AC3 at the same bitrate. It is worse than CD audio, it is worse than AAC. You lose a lot of quality compared to the original audio master and it is quite noticeable on a mid-range or high-end home theater surround system. AC3 (the original Dolby Digital) is a really old lossy digital codec from the mid-1990s. I'm going to strongly disagree with you on this. I stopped caring after ac3/DTS because all the news audio "advancement" looked like snake oil. Either Dolby TrueHD (lossless) or Dolby Digital Plus (lossy). It's metadata or wrapper that sits on top of an existing Dolby codec. So Dolby Atmos isn't a codec in and of itself. What are those metadata and how are they used by the receiver? Honestly, this video does a better job explaining it than I can: Sounds are objects mapped in space rather than hard coded to a specific speaker channel. It is Dolby's newest home theater format.
