Convert DTS/LPCM Audio to AC3

[Wilson.Wang]

In order to make my movie viewable on all devices, I removed the HD and then converted to ac3. Inspection of the file shows that the movie is now only stereo and not 5.1. Is that what ac3 is supposed to do?

Hi,

Please check the audio info of the m2ts stream file by MediaInfo.

Stereo?

Yeah, that's the easy part. I have a Denon 2308CI and Marantz 6005 (not in the same room!) both running from ION based XBMC PC's over a Gig-E network. I'll fire this up shortly & see what I get.

Post #28 shows you have the DTSHD master track. There is no other way to explain this.

Hi,

For convert DTS/LPCM to AC-3, is it clearly now?

now for playback, you will need a receiver that can decode Dts-HD MA, or a player that can decode...and via HDMI.

(if not, you will simply get the Dts core)

No, your disc has Dts-HD Master Audio...no "Uncompressed PCM" audio (like in my )

Uncompressed PCM, Dts-HD MA & Dolby TrueHD audio are all Lossless audio...aka the best.

Sorry, here's the HD folder.

Sorry, I'm still giggling at 3 straight posts of your icon.

Seriously, I didn't show it in that last screenshot but the box is available to be checked, but it is not. It's unchecked.

So sanity check: Does this disc even have LCPM? Am I getting geeked up about nothing? I want it ripped to my hard drive folder exactly as it is on the disc - no conversion, no compression, no nothing.

[crackinhedz]

when you copy your movie to the Hard Drive, try re-opening up with fab (your folder, not the bluray disc)...what audio does it show?

[crackinhedz]

looking around google I foudn a few posts about MediaInfo not showing Dts-HD MA or Dolby TrueHD correctly...could be the problem?

where are you having an issue, during playback?


Its definitely not converting to AC3, so that's not an issue.

[crackinhedz]

what about here when you are in the process of setting up...

[zimdba]

It's unchecked.

Format : DTS
Format/Info : Digital Theater Systems
Format profile : MA / Core
Bit rate : 1 561 Kbps / 1 510 Kbps
Compression mode : Lossless / Lossy

that's Dts "core" you have there...you must have the "Remove HD audio" selected.






make sure you do not have this checked.

So here's what MediaInfo has to say. I can only imagine that since it's ~1500Kbps audio that it's LPCM
