Is there a way to add DRC when encoding DTS 5.1 to AAC 5.1 with eac3to? I am encoding my movies for iPod and would like to compress the audio more for better hearing in loud places. I know about -keepdialnorm but I would also like to add medium DRC. I remember besweet could do it, but I don't think besweet works with neroaacenc.

When I'm trying to extract the mono LPCM track of Solaris Blu-Ray, to LPCM also, the resultant file is speeding up incredibly (presumably because eac3to assumes a minimal of LPCM 2.0 or something?). Dunno what that is, but would be nice if it gets fixed some time.

SUP title traction is still less than stellar, to be honest, with time-offsets often being way out of sync (like everything starts +1 hour later or some such); tsRemuxeR does a better job of it. Would be nice if that ever got fixed as well.

Tried to decode DTS to 16 bit wav using -16 option, but the output was 24 bit. Is it proper behaviour?

I understood my mistake: -16 is input option not output. Thanks, Weirdo.

By default DTS (like all lossy encoder) is always decoded to 24 bits, no matter the bitdepth of original source what is irrelevant.

if have a weird problem with eac3to 3.24 and more gui

i upgraded to windows 7 and when i start eac3to with the more gui i get a very weird behavior. i load a blu-ray and everything is fine. but if i select a title from a blu-ray i get stuck in old encode. i download a new copy of both (eac3to and more gui) but the error sticks with it. this also happens when i select 'test external filters'

thiugh, it's not happening when i run eac3to in cmd mode which i don't like... i'm a gui person ;)

is there any way to reset this behavior?

Are you supposed to run the eac3to.exe? or do you use Start --> Run command prompt and then type eac3to input. ??

is that eac3to.exe supposed to close itself after double clicking it?

if you dont run command prompt, then yes :p

How would I go about starting eac3to? It shows a log when I drag a file to it and shows the files in that 00000 named file, but then it auto closes eac3to?
Is there a way to keep it open?
Or what do I do after that?

When you are not skilled enough to type full command line yourself then try some GUI for eac3to - there are at least 4 of them, I personally prefer UsEac3to but it's up to you to pick your favorite. See the initial post of this thread for other GUI candidates.

one more question -

is there a way to pass extra parameters to NeroAACEnc? I need to specify -he in the command line, but eac3to won't recognize it.

tebasuna51

11th July 2011, 13:21

Use -quality=0.30 or less, then the output is -he

nibus

12th July 2011, 09:21

The quality I need is low enough (0.15) that it is defaulting to HEv2 which won't work on my device.

nurbs

12th July 2011, 10:17

You can pipe stuff from eac3to to the Nero encoder.
eac3to input.data stdout.wav | neroaacenc -q 0.15 -he -ignorelength -if - -of output.mp4
Fill in paths were needed for eac3to, input, neroaacenc and output. The important thing is to have eac3to output to stdout and nero input from stdin (-if -). You also need -ignorelength IIRC.

Boulder

12th July 2011, 13:05

Do you happen to know whether qtaacenc supports piping?

nurbs

12th July 2011, 14:26

Works like Nero. You need a "-" (without the quotation marks) where you normally put the input file and most likely also "-ignorelength".

I have been attempting to back my BluRay LotR EE discs. My Flac encoded audio is distorted and out of sync. I have not had this trouble with any of my other discs. I use EAC3TO and HdBrStreamExtractor as a gui. I have the TMT codecs loaded and my log show them being used. Has anyone else seen this issue and what can be done about it?

There are two problems with DTS-MA 6.1 (like included in BluRay LotR EE discs).

- You need ArcSoft Decoder v1.1.0.0, other like v1.1.0.7 make wrong 6.1 decodes.

- If you downmix DTS-MA 6.1 to 5.1 with eac3to the surround channeles are wrong mixed.

What's the best way to ensure the correct version of that codec? When the discs are played (w/TMT3) they play fine.

piranha (REAL 3D + 2D)

I created the iso using anydvd HD, then using clownBD I'm trying to backup the 2D form

There are two tracks

1) 00005.mpls, 00007.m2ts, 1:28:20
- Chapters, 12 chapters
- h264/AVC, 1080p24 /1.001 (16:9)
- DTS Master Audio, Italian, multi-channel, 48kHz
- DTS Master Audio, English, multi-channel, 48kHz

2) 00004.mpls, 00005.m2ts, 1:28:20
- Chapters, 12 chapters
- h264/AVC (left eye), 1080p24 /1.001 (16:9)
- h264/AVC (right eye), 1080p24 /1.001 (16:9)
- DTS Master Audio, Italian, multi-channel, 48kHz
- DTS Master Audio, English, multi-channel, 48kHz

so I selected the 00004.mpls and then the left eye stream with DTS Master Audio, Italian and italian subtitles
eac3to is logging plenty of "The source file seems to be damaged - discontinuity" and cannot demux
It doesn't seem a bad rip because I can demux 00005.mpls without any errors.
Any ideas?

And a second question.. is there a way to do multiple edits? it's boring to have to create 4 files to do 4 edits..

Hi,

...- If you downmix DTS-MA 6.1 to 5.1 with eac3to the surround channeles are wrong mixed.

since this is exactly what I want do do ( 6.1 DTS-MA -> 5.1 Flac ), could you please give me a hint what's going wrong when downmixing with eac3to and version 1.1.0.0 of the dll ? My idea to circumvent the problem would be to decode the 6.1 DTS-MA to 7 seperate wave-files, to do the downmix to 5.1 manually in a correct way using audacity and then to reencode the wavs to a 5.1 Flac.

Thx in advance, Nanobot

In this thread: http://forum.doom9.org/showthread.php?p=1465610#post1465610

Now eac3to make the downmix 6.1 -> 5.1 with:
SurroundL = Cs + 0.7071xRs
SurroundR = Ls + 0.7071xRs

And must be:
SurroundL = Ls + 0.7071xCs
SurroundR = Rs + 0.7071xCs

Yes, you can decode the 6.1 like wav's and make the mux manually.

Hi,

:thanks: for the link and the information, that is accurately the info I was looking for.

Nevertheless, I would suspect that this downmix matrix for the surround channels might result in levels above 0dB for Ls and Rs ? Or are the levels for Ls, Cs and Rs in a 6.1 DTS-MA file are already limited to values where Ls + 0.7071 x Cs and Rs + 0.7071 x Cs can't exeed a level of 0dB ?

If my concern is true, would it be ok just to normalize those two channels after the downmix, or do you have a recommendation how to avoid this probable problem ?

C.U. Nanobot

tebasuna51

20th July 2011, 02:50

Yes, we always need normalize after a downmix.
eac3to normalize the 6 channels automatically.

Use Google with search functions

dts-ma 6.1 site:forum.doom9.org

Most search engines in forums don't allow you to search things less than 4 characters.
"quotes" are usually required.

Google has a better chance, since it's diverse.
dts-ma will show you dts-hd ma, dtsma, dts ma, etc with Google.
With the forum search, it looks for exactly what you type in.

quick question:

Is it possible to disable that annoying "Pling" sound when done with a file?
And is it possible to skip the 1-pass wav file and encode directly to in example a m4a aac file or is that wav file needed?

Rename or delete the file "success.wav" in your eac3to directory.

And is it possible to skip the 1-pass wav file and encode directly to in example a m4a aac file or is that wav file needed?
I haven't tried, but adding "-no2ndpass" to your commandline might do it. The wav is written so that if a second pass is necessary, which isn't always known before the first pass is complete, you don't need to decode the audio again. You might have audiable problems if you use that option.

I'm having trouble converting the following stream to LPCM:

DTS-HD Master Audio English 1064 kbps 1.0 / 48 kHz

The resultant LPCM file is playing way too fast. I take it because there's no official LPCM 1.0? In any case, how do I convert this to a normal, playable, LPCM track?

Thanks.

About the eac3to 6.1 DTS-HD downmixing 'bug', if I output to individual WAV files could someone let me know how to mix the back center channel with the surround left/right channels manually/correctly please?

Could I do it with eac3to, eg: eac3to rightsurround.wav+backcenter.wav output.wav

tebasuna51

3rd August 2011, 09:56

Nope, you can use an audio editor (like Audacity or others), a command line tool like sox, or Avisynth (with BeHappy, wavi, ...) to do a mix like:

BL = 0.5858 x SL + 0.4142 x BC
BR = 0.5858 x SR + 0.4142 x BC

The recommended .avs' can be something like:

sl = WavSource("D:\...\SideLeft.wav")
bc = WavSource("D:\...\BackCenter.wav")
MixAudio(sl, bc, 0.5858, 0.4142)
Normalize()

To obtain BL channel, and for BR channel:

sr = WavSource("D:\...\SideRigth.wav")
bc = WavSource("D:\...\BackCenter.wav")
MixAudio(sr, bc, 0.5858, 0.4142)
Normalize()
