I'll just go E-AC3 to PCM. It's quick & easy. Space is not an issue.
On a side note, I noticed the following: Converting to DTSHD-MA saved about 40% in space over the .WAV produced by eac3to. For some strange reason converting to DTSHD actually produced files larger than DTSHD-MA. |

With the Lord of the Rings trilogy just announced as DTS-HD MA 6.1, I'm guessing it will be just like the Harry Potters and The Number 23 where it has a DTS-ES core and the MA information is not extracted as 6.1 by eac3to, but only played properly when decoded by a player such as the PS3.
Is there any way that eac3to can convert such tracks to 6.1 FLAC? Or are we simply limited to 5.1 for those? |

Hmm well that's false advertising stating 6.1 all over the back cover... that goes for both Lionsgate (T2 Skynet) and Warner (HP 1& 2 ultimate, Number 23, LOTR trilogy).
They should say 5.1 ES not 6.1. X-men 3 seems to be pretty much the only BD which is marked as 6.1 which is actually encoded as such. Here I thought I might have been able to watch LOTR trilogy in 8-channel FLAC, rather than 6-channel FLAC |

1) DTS-ES, 6.1 channels Called DTS-ES discrete, and the Back Center is encoded digitally like a independent channel. ArcSoft decode this like 6.1 channels 2) DTS-ES, 5.1 channels Here the Back Center channel is encoded in Back Left/ Back Right channels in analog mode. This is DTS ES-matrixed. When you send this stream (SPDIF or HDMI) to a receiver DTS-ES compliant you can obtain a 6.1 output. ArcSoft decode this like 5.1 wav, but the Back Center channel is still matrixed in Back channels. When you send this wav (or Flac decoded) to a receiver like PCM 5.1 (only by HDMI) you can obtain a phantom Back Center channel.

AFAIK ffdshow can't extract the back center channel.

But anything which isn't originally discrete 7-channel and only 6-channel with ES it seems I'm out of luck |

Hmm, after audio overlaps are detected, it seems that eac3to no longer runs audio encoding concurrently. Say extract and convert two DTS-HD MA tracks to FLAC and both of them have audio overlaps, you'd expect eac3to to run the 2nd pass, fix the overlaps, and do the conversion of both at the same time, but the 2nd track's conversion begins only after the first one has finished. :|

DTS 96/24 decoding
Sorry if this has been covered already but this thread is overwhelming to search.
Code:
eac3to v3.17 command line: "c:\program files (x86)\eac3to\eac3to.exe" track01.dts "01 - .flac" ------------------------------------------------------------------------------ DTS-96/24, 5.1 channels, 0:03:12, 24 bits, 1510kbps, 96khz The ArcSoft and Sonic decoders don't seem to work, will use libav instead. Decoding with libav/ffmpeg... Remapping channels... Reducing depth from 64 to 24 bits... Encoding FLAC with libFlac... Creating file "01 - .flac"... eac3to processing took 24 seconds. Done. Thanks. Appendix: I have downloaded and installed a trial copy of ArcSoft TotalMedia. eac3to can't find the DTS decoder even after adding the ArcSoft decoder directory to the Windows PATH variable (which by the way it is not what the first post says but it's "C:\Program Files (x86)\ArcSoft\TotalMedia Theatre 3\Codec". Any help on this additional problem? Last edited by utenteanonimo64; 7th March 2010 at 13:47. Reason: more problems! |

C:\Program Files (x86)\ArcSoft\TotalMedia Theatre 3\Codec and dtsdecoderdll.dll is version 1.1.0.7 which according to madshi's instructions should be compatible with eac3to. As I said I have added the above directory to PATH enviroment variable and I have also copied all dts dlls into the eac3to directory. But if I run "eac3to -test" eac3to cannot find any external decoder. Is it because TMT is a trial version? Any help is appreciated. |

Can't help you there I'm afraid - it just worked on my system (WinXP) without any fiddling about.
Try looking through this thread. |

AC3: The dialnorm value tells us how much headroom there is between 100% volume and speech volume. DTS: The dialnorm value tells us how much the decoder should lower volume. Because of that a -27dB AC3 dialnorm value equals a -4dB DTS dialnorm value. Now of course eac3to could change the display of the dialnorm values, so that AC3 and DTS match. But I'm not sure if I should do that? What do you guys think? Quote:

delaycut can do this better, but since it doesn't have a DTS encoder, either, it simply uses a default silent DTS frame - which doesn't have the DTS-ES flag set, of course. Quote:
Just delete or rename the wav files. Quote:
I'll add that to my to do list. |
