Regarding audio delay: if DGIndex tells me that the audio track has +144ms delay, do I need to use +144ms or -144ms in eac3to's command line? It's a silly question but there is no obvious answer

I feel like I am being mocked here What tebasuna51 (btw, thank you for the clear answer!) explained is - as I suspected - sort of the opposite of what eac3to is actually suggesting by the above message IMHO. It is confusing because eac3to message refers to the delay it tries to apply to the audio track, and not to the (resulting) delay the audio track already has.

Not at all It's just very confusing at times. I think I've always used the opposite but since the delays are usually rather small, it's not easy to determine which way is the correct one.

The info (also MediaInfo) always show the delay than you need apply.

Young Frankenstein
There is a stream that eac3to really doesn't like:
9: DTS Express, English, 1.0 channels, 24 bits, 96kbps, 48kHz I can demux it but nothing more. Tried with TotalMedia libraries, LibAV ones but whenever I am going to export to wavs, it tells me some kind of errors. Any idea about how to convert it?

Hi to all!
Trying to convert a DTS track to AC3 using "eac3to" leads me to an unusual problem. DTS (ES):2.77GiB, 4h 23mn = AC3: 1.34GiB, 5h 0mn. I want to mention that this is only the 2nd time I'm facing this problem after more than 200 conversions. The first time, I found a solution in this forum with adding a parameter to eac3to, but now I'm searching hours & hours with no luck. |

Using as usual the default command "eac3to.exe input.dts output.ac3" was the reason of this weird effect (for this & only dts stream). After trial & error and changing the command to "eac3to.exe input.dts output.ac3 -libav" ..did the thing. Anyway .. "Sparktank" for your interest to give a help. |

Channel mapping problems with LotR ext. BDs
Hello,
I have a problem with eac3to that drives me crazy. I want to decode the DTS-HD MA streams of my release of x and encode them to FLAC so that my Linux audio players can play the full sound, not just the DTS core. I have downloaded eac3to and the ArcSoft DTS Decoder 1.1.0.0 plus the HdBrStreamExtractor GUI. The output WAVE files (or FLACs) have all 7 channels and the sound is nice but they appear to have the wrong channel mapping: Voices are very low and often come from only one side (I have only stereo speakers) and once in a while come with strange echo. But when I import them into Audacity and play them with the editor the output is correct. This however has no effect on the Audacity export: 6.1 channel export has the same mapping problems as the original file. My players are not the problem, they can play every DTS, AC3 and TrueHD stream correctly. I read something about "strange setup" but I can't understand if this might be the problem. I have absolutely no knowledge about audio mastering. The issue affects both English and German streams. The Audacity export window offers the option to remap the channels but I have no clue what could be the right choice. So I really hope you can help me: I uploaded a piece of 6.1 export from Audacity in Ogg Vorbis and it would be really nice if someone could tell me the right mapping. Thank you very much in advance! http://www.2shared.com/audio/boFrWT5...-wrong-ch.html - I hope not to violate against forum rules with this. Off this topic I want to say something: It may sound ridiculous but I miss a "tutorial". I lost hours in trying to understand what these freeware tools do and how to set them up with decoder and codecs. The learning curve is very steep but not because I am a idiot but 'cause most of your tools lack a proper documentation. I am a Linux user and I am used to find answers in reading docs. It's really great that there are freeware tools like eac3to but I can't understand why the authors of such media helpers don't make the source code available. The last version of eac3to is from 2010? I read something about a GPU video encoder the author is writing since then and the promise to get back to work on eac3to when this encoder is final. But since 2010 no progress with eac3to. In this time the program could have been matured and bugs could have been fixed from others but they can't do it because they don't have the source code. It is his right to hold the source for himself but I truly can't understand the reason. It doesn't seams to be his plan to make commercial profit out of it. But no hard feelings, this are just my thoughts. Last edited by frumble; 18th March 2014 at 01:36. |

Unfortunately 6.1 is not defined in FLAC. So players might decode it not as you expect, unless you do a downmix.

This has actually been a bit of a constant problem for FLAC.
One user here goes on about it... Dear (people), please stop using 6.1 FLAC I remember reading about 6.1 FLAC in other places. Personally, I'd stick to the CORE or even a conversion to AC3@640, as 640 is perceived to have transparent quality to the master file. With some BD rips I do, I'm quite happy using only the core for maximum compatibility with my BD player that can playback MKV (with original h264/VC1/MPEG). It's not a significant compromise between lossless and core, I'd stick to CORE audio. The human ear wouldn't really be able to pick pu the difference too much.
