a technical question: when comparing 2 source.track -> .wav files of the same channel from different source types (e.g. center channel of 5.1 ac3 and flac or left and right channel of 2.0 ac3 with left and right channel of 5.1 flac) and looking for their different delays is it technically correct then to look where the first tiny bit of sound occurs in the channel graph? what I mean is that a flac track of course has a higher quality as an ac3 track and this difference must be located somewhere. so could it be possible that the flac track has numerical more digits in the graphs at the beginning of the track compared to the ac3 track so that this kind of delay meassurement is wrong, or is this difference of sound quality only to be found in the amplitude of the graph, that it only spread in the vertical, but not the horizontal direction of the graph?

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 |

Will i twork with DD EX tracks? By the Way, i compared all Surround/Back Channles from dts es discrete with the test matrix reencode and arcsoft -7. Theyre all looking fine and identical compared to the original dts es discrete.... However, Madshi will make it ,as always |

The analog extraction isn't perfect, like you see there are BL and BR parts (2%) added to the BC channel.

yeah..it should be tested more..im not sure
Strange, i cant reproduce my Test. eac3to/arcsoft -7 crashes on the dts es matrix reencode. But it works with other matrix dts tracks! Madshi should take a closer look, he is the master Last edited by ACrowley; 29th October 2008 at 16:25. |

Hi guys.
How can i shorten this: Code:
eac3to E:\VIDEO_TS\VTS_01.vob+E:\VIDEO_TS\VTS_01_2.vob 2: C:\KB\video.m2v 6: C:\KB\dtsaudio.dts 5: Code:
eac3to E:\VIDEO_TS\[VTS_01_1+VTS_01_2].vob Code:
eac3to E:\VIDEO_TS\[VTS_01_1.vob+VTS_01_2.vob] _ _ _ _ |

@ACrowley, are you using a different ArcSoft decoder version? FWIW, I'm getting the same crash as tebasuna51... Quote:
However, I'd strongly recommend that you reconsider your transcoding method. The "clean" 5.1 core will result in worse audio quality than the eac3to produced 7.1 downmix because the 7.1 source has a higher quality in every single channel compared to the core 5.1 track. Even if you're afraid that eac3to's 7.1 -> 5.1 downconversion is worse compared to what the studio did, still the front channels and LFE will have a higher quality if you use the full DTS-HD track. So IMHO using only the core is a bad idea. Quote:

"eac3to sourcefile test.wav -mono -50mb" Quote:

Or if you want me to check it, please upload a small sample of the original 7.1 English DTS track, please? Quote:
Please stop asking the same question over and over again. I've already answered it a while ago. |

By calling eac3to from inside "E:\VIDEO_TS". Then you don't need to use any paths for the source files.

No, but I didn't think a sample was necessary. I was able to convert it to wav using a previous version (can't remember which), but it doesn't work ever since you added the deeper bitdepth analysis, leading me to believe its a small bug introduced in your code only recently.

You should have "E:\VIDEO_TS\>eac3to VTS_01_1.vob+VTS_01_2.vob". I'm not asking for a sample. You posted a log (which doesn't contain any error messages) without any further comment or question. What am I supposed to do with the log? I don't even know what you want from me. |

I don't know if DTS PRO ENCODER have a switch to apply or not the phase shift to surround channels (like Dolby Encoders have)
