eac3to - audio conversion tool

One of the best feature requests i've heard after my last night trial

(Btw, TrueHD gaps can not be repaired )

Second pass:

Audio gap description file detected, can't be used for TrueHD/MLP, though.
Audio gap description file detected, will be used for processing...
[v01] Extracting video track number 1...
[a02] Extracting audio track number 2...
[a03] Extracting audio track number 3...
[a03] Realizing DTS gaps...
[v01] Creating file "E:\output\video.h264"...
[a03] Creating file "E:\output\audiodts.dtshd"...
[a02] Creating file "E:\output\audiothd.thd+ac3"...
[a02] Audio overlaps for 5ms at playtime 0:46:24.
[a02] Audio overlaps for 5ms at playtime 1:28:23.
[a02] Audio overlaps for 5ms at playtime 2:33:42.
[a02] The audio gaps/overlaps technically can't be removed from the TrueHD bitstream.
[a02] In order to remove them you'll have to transcode the audio to another format.
Video track 1 contains 230070 frames.
eac3to processing took 31 minutes, 57 seconds.
Done.

The question here is:
Shall i re-encode to another format after or before merging?

The TrueHD to DTS isn't working in the 2.64 version. 2.60 that I have works fine.

The new version names the surround channels as BR/BL and Surcode gets confused cause it doesn't find SR/SL named channels and closes.

@madshi:

Can you implement a missing Option? :

-slowdown24 and -speedup24

for 24.000 -> 23.976 and 23.976 -> 24.000 conversions ;-) ?

+1. Would be a great feature.

eac3to reports insane audio delay. DGIndex demuxes audio without problems.

Done.

That was me. I have spent several months working on that and I think it's impossible. I have so far gone through the thread three times and compiled lists of what posts I think should go where, and they are different each time. The development posts and usage questions are inextricably linked. Really I think that we as eac3to users should just focus on making the eac3to wiki comprehensive to alleviate the enormous amount of usage questions that pop up in this thread. Or we could just start a new eac3to usage thread.

That feature is broken for me in the GUI.

I do agree.... Lets start a new eac3to usage thread?
I think you have a collected FAQs on eac3to as well?
So i think you are the one who should start this thread.
I suppose nautilus7 will contribute as well.

Then I propose a new thread for usage with an opening post linking to the WIKI and to several posts in this thread that address frequently asked questions. Unfortunately my lists of posts from this thread that I made are all about development so I'm not currently in a position to supply the list of FAQ posts. I suppose I could whip something up though.

i did a quick search of the thread and didn't find anything related to this, sorry if its a dupe suggestion.

When eac3to finds gaps while doing a DTS (and i believe AAC, FLAC) it outputs as PCM and puts up the message about gaps being found before running the external program. I was wondering if you could add an option (maybe something like "-killOnGaps") that will not start that second part.

I have some automation that will run a 2nd pass if a .gaps file exists, except when I walk away my computer still has to spend 30 or so minutes making a DTS file from the first step that was filled with tiny gaps.

I'm not sure exactly how you designed the program, but if you could this would make things a lot easier for me. Still loving the program madshi!

Dear Madshi,
thanks for the wonderful program eac3to which you keep improving over and over! I have a question: can this program create a FLAC file from six WAV files? And what would be the command line to do this? Regards, va1aY

It has to collect the info of the gaps first, so i guess it is impossible.
But automating the second pass is possible, i think.

I have an lpcm track (Crank blu-ray) where eac3to "sees" 7.1 channels, but only 5.1 of them seem to contain audio data. For me it is no problem, I assume I could specify the number of channels manually. I just thought maybe it could be fixed in eac3to. Tell me if you need a sample.

How do I get 6th channel doubled? (Creating a 8 channel FLAC from 6.1 DTS-HD Master Audio)

I searched the thread but can't find this one. I remember reading that this feature was disabled by default since a while back.

[Kurtnoise]

Just to have an info: is it possible that a DTS-MA stream can be stereo ?

edit: reply to myself - yes...

Just use the "-double7" option.

Hi! I wanna report an error decoding DTS-HD MA:

Here are track specs: DTS Master Audio, 1.0 channels, 16 bits, 48khz (From "For A Few Dollars More")

Decoding with ArcSoft DTS Decoder...
The ArcSoft DTS Decoder reported an error while decoding.
Aborted at file position 16384.

Decoding with DirectShow (Sonic Audio Decoder)...
eac3to crashed...

last one crashes all the way at the end of file (seems so with the "-" reaching to the end)

ArcSoft DTS Decoder (1.1.0.0) works fine
Sonic Audio Decoder (4.3.0.169) works fine

[saint-francis]

Try your process with the -test switch to determine if you are working with a good rip.

[yfed]

what do you mean?
"-test" just checks if the external filters are installed & working

I cant use "-check" because I no longer have m2ts. But I remember that everything from it demuxed successfully
