I found one thread mentioning GraphEdit to determine which audio filters are setup, but what the heck is GraphEdit (I eventually found it and installed it) and how the heck do you use it (from a n00b perspective). Well, that's what I had done (ran the TMT installer and TMT works fine and properly plays back DTS-HD files), but when I run the command line "eac3to -test" to see which decoders are "installed" it always shows Arcsoft as not installed.Īnd this is where I've run into a dead end trying to resolve this. I'm just missing something or a componentĪfter pulling my hair out, Googling until my eyes fall out, I think I've run into the crux of my problems with DTS-HD files: eac3to doesn't seem to acknowledge that I've installed ArcSoft TotalMedia Theatre, which I assume installed SOMEWHERE it's proprietary Arcsoft DTS-HD decoder.īut everywhere I read regarding eac3to and external decoders is that you simply "install said software" and basically, eac3to will recognize it no matter where you install the software, eac3to included. I'm sure there HAS to be a way, because, again, the option to convert to LPCM is there in multiAVCHD. Transcoding DTS-HD/TrueHD with PS3 Media Server, in my experience, causes the playback to be choppy, even with dual quad-core 2.8 GHz Harpertowns. Now, if I didn't want to experience high fidelity sound at all, and can live with standard DTS/AC3 5.1 audio, then I can either extract/convert to DTS/AC3, or have PS3 Media Server transcode. The USB drive method is rather clumsy in that I would have to attach a hard drive to my PS3 whenever I wanted to watch a particular movie, and I would have to pre-arrange the folder structure to that movie I wanted to watch (tho there are utilities to have multiple AVCHD folders present and be able to select which movie to watch). I stream via PS3 Media Server as I want one place to have all my media on. PS3 will not send out any DTS-HD MA or TrueHD audio to the receiver unless both conditions are met:ġ) Connection to AV Receiver must be HDMI (optical Toslink doesn't have the bandwidth to send DTS-HD nor TrueHD)Ģ) The source must be from a Blu-Ray disc, from an AVCHD folder structure on a USB drive, or as LPCM streamed from PS3 Media Server I have an HDMI receiver and 7.1 speakers. The main reason I want no conversion (down sampling) is to enjoy the fullest, high fidelity audio. But do I need more that what is normally bundled with multiAVCHD to actually get DTS HD to LPCM conversion to work as it seems multiAVCHD relies on eac3to?ĭo I need to get TotalMedia, and if so, does it automatically add a plugin to eac3to so I can then bring full functionality to multiAVCHD, or do I use TotalMedia as a stand-alone app and convert the DTS-HD audio track within it? Glancing at TotalMedia, it seems more like a media player than an AV toolset. MultiAVCHD from all that I've read claims to be able to handle DTS-HD MA conversion to LPCM heck, the option is right there on the Subtitles & Audio tab. ArcSoft TotalMedia Theatre), but it does include libav to allow TrueHD decoding, which supports why I can convert TrueHD currently. Some Googling and I find that eac3to does not include a native DTS-HD audio decoder and the only available "plug-in" for it are commercial software (e.g. Now I'm trying to convert DTS-HD to LPCM but all of the m2ts files I throw at it fail, with the jist being that eac3to refused to convert audio. As the MAC Mini has no HDMI output you can never achieve more than 2 channel HD audio, the best you can get is SD DD/DTS or 2 channel PCM.I've been using multiAVCHD to convert TrueHD to LPCM with no problems. From what I can tell your amp can only handle stereo via HDMI so you are not getting HD audio.Īpart from PCM there is no other multi-channel lossless format available if you can't handle Master Audio or True HD. If your amp can only handle stereo (2.0) audio via HDMI you are getting Pro Logic II/DTS Neo 6 de-matrixed sound that is not as good as HD audio and arguably worse than SD DD/DTS. If your amplifier can take 5.1/7.1 PCM then you are getting the full soundtrack from a Blu-ray, the Blu-ray player is un-compressing the DD/DTS. The new DD True HD and DTS HD Master Audio have been expanded to full 7.1 channel and can losslessly encode all the PCM audio, and are a perfect copy of the PCM but requiring less storage. The standard DD and DTS codecs are like MP3 and cannot stores all the 5.1 PCM data so instead discard some of the information, this is NOT lossless and is LOSSY. The problem with PCM is that it takes alot of space and is therefore compressed with codecs such as Dolby Digital and Digital Theatre Sound. LPCM is the uncompressed audio, currently Blu-ray supports upto 7.1 on releases but it can theoretically continue increasing.
