thank you Madshi,just there has a problem.i make 3 step
1) use eac3to demux TrueHD track directly from BD/HD 2) type command "eac3to 00001.thd audio.thd" "eac3to 00001.thd audio.ac3",demuxing to ac3 core and lossless part 3) rename audio.thd to audio.mlp,and import to Scenarist.at 100%,its hung!!!about 2 minute,get a error message "External component has thrown an exception" where is problem?Madshi |

If we name source channels like Rear: RL, RR, RC and RL' = +90º phase shift RL RR' = -90º phase shift RR seems the phase shift is make at encoder phase and is the same for 'matrix' and 'discrete' DTS-ES in all the tests. The output channels after encode to 3/3.1 DTS-ES discrete and decoded with ArcSoft: 1) 3/3.1 -> 5.1 (like previous test) SL = RL' + 0.71 x RC SR = RR' + 0.71 x RC Ok 2) 3/3.1 -> 6.1 BC = RC SL = RL' SR = RR' Ok 3) 3/3.1 -> 7.1 SL = 0.40 x RL' + 0.60 x RC SR = 0.40 x RR' + 0.60 x RC BL = 0.75 x RL' BR = 0.75 x RR' Seems wrong: RC only in Side and most Rear part in Back, I think must be the other way, Side <-> Back ---------------------------- The output channels after encode to 3/3.1 DTS-ES matrix and decoded with ArcSoft: 1) 3/3.1 -> 5.1 SL = RL' + 0.71 x RC SR = RR' + 0.71 x RC Ok 2) 3/3.1 -> 7.1 SL = 0.71 x RL' + 0.50 x RC SR = 0.71 x RR' + 0.50 x RC BL = 0.71 x RL' + 0.50 x RC BR = 0.71 x RR' + 0.50 x RC For me seems ArcSoft can't recover the RC mixed in RL-RR because RC must be present only in Back channels. 3) 3/3.1 -> 6.1, eac3to crash with this bugreport.txt The report was made with 2.70 but is the same with 2.72, I send the 2.70 bug because was made after a reset with the minimum of soft running. |

DTS-HD 7.1 works fine for me, HDDVD --> BD with DTSHD-MA 7.1, using tsMuxeR. All demuxed using eac3to. Maybe try demuxing the individual track instead of the whole disc. Leon, as in the Professional on BD? Not in North America yet , one of my favs! |

I have always used TsMuxer from original BD and make a "movie only" m2ts, So I will see how it works when using eac3to first :-) |

Hey,
first, a big thank you for the program, it is a godsend But I do have a couple of quick questions... I have a RAW/PCM, 5.1 channels, 16 bits, 48khz track and would like to encode it to Dolby Digital 5.1. I know I can encode using eac3to by just specifying the output file as .ac3, but here's what I'm more interested in... When I demux the PCM track, here's the eac3to's output... Code:
[a04] Reading RAW/PCM... [a04] Swapping endian... [a04] Remapping channels... [a04] Swapping endian... [a04] Remapping channels... [a04] Creating file "D:\bluray\eng.pcm"... Code:
This might be a RAW/PCM file. Trying to figure out the details. This will probably take a while. Please be patient... The RAW/PCM file seems to be big endian. The RAW/PCM file seems to have a bitdepth of 16 bits. The RAW/PCM file seems to have 6 channels. RAW/PCM, 5.1 channels, 0:08:28, 16 bits, 4608kbps, 48khz This is probably a Blu-ray PCM track. Will remap channels accordingly. Reading RAW/PCM... Swapping endian... Remapping channels... Encoding FLAC with libFlac... The second question is about downmixing 5.1 to stereo (I know it's pretty much obsolete, but I need it in this case)... Assuming that the FLAC file above is OK (channels and all), can I just load that FLAC in i.e. meGUI (provided that I have madFlac installed). Would that downmix be OK? Is the alternative, adding a -down2 to eac3to when generating the FLAC also OK ? |

I personly dislike 7.1 downmixing from DTS-HD 7.1 files, when a "clean" 5.1 core is present. But is not possible to reencode directly in 1 step to ac3 from the -core. eac3to always sees the 7.1 MA and try to downmix from the extention. At the moment, first the -core must be exported, than you can ac3-encode from the 5.1 core. |

it can not be read individually since core is an obligation for DTS-HD format: system works in this manner: core+extensions. So if you want to re-encode it to ac3, eac3to must decode and downmix before encoding in case of extension is 7.1. EDIT: Some points: If you want to extract core dts (5.1) as is, use -core option. When you try to re-encode (or to make a simple revision like convert 24 to 16), not only eac3to but any program has to decode the original file first. If you don't ask eac3to extracting core, it is gonna directly try to decode DTS-HD which is 7.1 in your case. But default encoder (aften) is not able to encode to 7.1; so the original has to be downconverted to 5.1 by eac3to. Unless you use a pro encoder by Dolby, you will never able to get an 7.1 dolby re-encode; even in this case, as you guess, eac3to must firstly decode your DTS-HD. So difference between you and the guy from whom you taken the quote is; he is getting/or extracting a seperate ac3 (as is) from thd+ac3 combination -it is not a core, but he has to make a second command line since it needs a lossless thd as well. you, on the other hand, are re-encoding DTS-HD, not core. So the way you follow; extracting core dts and later, converting it to 5.1 is normal process. BTW; shift+arrow up repeats your previous command. Last edited by rica; 28th October 2008 at 02:23. |

If the raw/pcm track from your BD is the 'x' you can use directly: eac3to D:\bluray x: D:\bluray\eng_flac2.flac -down2 |

I compared only the BC Channels. And the BC looks fully identical as you can see in my Post But i think this can be fixed ? I hope so ,because i have a lot of dts es 6.1 "Matrix" Tracks on my HDD ,waitnig for a proper Method to decode all 7 CH for a reencode ( all PAL Audio Tracks/Target is PAL to NTSC-reencode to dts es 6.1 "discrete") On the other Side, i dont think the 6.1 Output from matrix 6.1from Arcsoft is sooooo wrong..better then nothing ?! |
