![]() I appreciate that 960kbps DD+ is only marginally better but the point was trying to provide the best work around in terms of sound quality. I’m not aware of anything that transcodes to something better than DD5.1.ĭD5.1 is DVD sound in the Atmos age. The reason I’ve gone to this bother is that DD+ is marginally better than DD5.1. My current BD player converts to DD5.1 on the fly. For instance see (a comment there also links to the Sonos community). There have been topics about this here on the Sonos forum too. Not clone or store digitally, just play and the audio is automatically converted to Dolby. This is the longer way round but you have more flexibility as the whole disc has been copied over. True (CloneBD is the best one IMO) but I wanted 1:1 copies so I could play the Dolby discs natively and if I switched to a system with DTS-HD support I had the DTS discs too. On the other hand if you want to have everything digital this is the way to go! There are also Blu-ray players that can convert on the fly seems like a much easier solution? However, for those who want to move away from physical discs this works very well. Making MKVs from Blu-ray Discs are really straight-forward but is no substitute for an “on the fly” solution or Sonos support by way of a firmware update. I don't think you can easily tell that its more comparable with “standard” 5.1 sound compared to HD sound. Please note that I had set my Zappiti (ie media player) to pass through bitstream so the sound send to the Arc via my TV was the sound played by the MKV file.ĭolby Digital Plus is quite a rare find on disc, however, it is really good, rich sound. Using Handbrake with the mixdown set to 5.1 channels (using E-AC3), the mkv produced was recognised by the Arc to be 5.1 channel Dolby Digital Plus.Īs a result, I could experience much better sound than PCM/stereo. 960kbps isn't great when we are downmixing from HD sound, but better than 640kbps. I tested this many times with many discs.Į-AC3/DD++ is better than AC3/AAC and DD5.1 as these are limited to a bitrate of 640kbps. I don’t know why 960kbps as DD+ (which the Arc supports) is up to 1.5mbps but I only got silence once I exceeded 960kbps. Re-coding to DD+ uses the E-AC3 codec and it works on the Arc with a bitrate of up to 960kbps. All other open source applications did not only to DD5.1 using AC3, with a bitrate limit of 640kbps. Why Handbrake? It was the only software which definitely converted DTS-HD to Dolby Digital Plus. ![]() To play DTS-HD, DTS5.1 or DTS I used Handbrake to create MKVs of the main movie (ie the single title on the disk-Handbrake will usually find it for you). Highly recommended Atmos film: First Man-skip to the take off scene. Really towers above the PlayBar kudos to Sonos. However, even by itself, it is very impressive. The Arc is absolutely magnificent, with a Sub and two rear Play 1s. I was able to play all Dolby encoded discs from the Hard Disk and experience TrueHD, Atmos etc. If you don’t want 1:1 copies for your media system/set up, you can skip this. I made 1:1 copies of the disc using AnyDisc and MakeMKV. I even though about returning the Arc or buying a second one to use for DTS alone, which was a bit mad.Īs it happened I just bought the Zappiti 4k system (which is amazing!!) and was in the process of transferring my BDs to it when the Arc arrived and presented this problem. ![]() Before I went this route, I looked for every transcoder, box, set-up going but there is nothing. Bit it does require you to be much more technical and basically, be capable of ‘ripping’ or copying your Blu-ray Discs. I say most with good reason, out of the 100 discs I have of the most popular and mainstream films, 80% are DTS-HD.įor the Play Bar I had a decent work around which produced DD5.1 or DD Stereo (see here: ).įor the Arc it was really annoying to have to even look for a work around, however, I think I have a solid one. So called, because, it does not support the sound encoding used on *most* Blu-ray Discs. Hello all, I thought I would share my work-around for this much derided problem: lack of support for DTS sound on Sonos’ so-called home cinema set-up. ![]()
