eac3to - audio conversion tool

[MrVideo]

Interesting. I've never seen anything but WAV uncompressed PCM audio.

Then, that leads me to this question... why put DTS compressed data into a WAV file? I'd just leave it as a DTS file.

The audio data in DTS is encoded (compressed like a zip) the audio data in WAV file is decoded (uncompressed PCM data)

I just looked in another song I have in DTS 5.1 WAV format

A dts_5.1_wav is not a correct WAV file because the header don't show the content. The fake header show a PCM 2.0 44.1KHz just to lies a burner and burn a CD-Audio.

I just wanted to wrap the DTS file in WAV format, not to convert it.

Then you want burn CD-Audios 5.1
Try spdifer, a AC3Filter tool.

Like you can read, only to burn a CD Audio.
Some CD players can send the DTS 5.1 and play surround.

tebasuna51, you are the man!



spdifer worked like a charm! I got my WAV file 5.1ch, at the same size as the DTS original file !!

... and I learned something about DTS and WAV files.

I get an error when I try to use eac3to with SurCode DVD–DTS v1029. Is this a problem with eac3to or SurCode DVD–DTS v1029? I mean, is eac3to incompatible with SurCode DVD–DTS v1029?
When I use SurCode DVD–DTS v1021 I get no error.

The error sounds like: "Pressing the Surcode "Encode" button didn't seem to work", but when I directly use SurCode DVD–DTS v1029 I don't get any errors at all.

What is the latest compatible version of SurCode DVD–DTS?

Thanks.

I wish there was a way to have eac3to in Linux without wine. I don't have a GUI installed, so I can't do wine. I run eac3to on my Windows machine to rip discs, but sometimes I forget something and need to fiddle with large files after I've written them, and my disc is across a network. Being able to have it on my Linux would speed things up quite a bit. I would only need basic libavcodec functionality.

Is this still needed, may I ask. Changelog mentions a bug fixed in version 3.21...

fixed: 6.1 DTS decoding with ArcSoft resulted in wrong channel order

Many thanks.

[tebasuna51]

The decode is OK, only need a remap when downmix 6.1 to 5.1

Thanks for confirmation

I have previously converted 25.000 fps audio to 23.976 with -slowdown switch, how do I convert 25.000 to 24.000?

I have import Blu-ray with strange 24p (not 24.000/1.001) h.264 and DTS. I'm trying to add AC3 audio into it from my older PAL DVD.

[ramicio]

Are you even sure the audio is going to line up? What is the fixation with the audio from the DVD?

Anyway, you would first add the "-25.000" switch, to tell it to assume the material is 25 FPS, and then "-changeto24.000".

I've always adjusted the delay after conversion. I'm adding dubbed audio from DVD to import blu-ray for my 3 year old.

I've thought you need to convert audio with -slowdown not -changeto switch?

[ramicio]

I still don't get it. Slowdown is deprecated, and only for 25 to 23.976 conversion.

Is it 1.1.0.5 or 1.1.0.0 for 6.1/6.0 audio and 1.1.0.8 for anything else ?
Some people claim that 1.1.0.0 is the best for 6.1/6.0 but others claim 1.1.0.5 is best because 1.1.0.0 lacks many bug fixes ?
I found the following pieces of information around doom9 forums but i'm still confused to which version to use to avoid any bug ?

- 1.1.0.0 can decode DTS(-HD) 6.1/6.0 but can't decode non-standard 7.1
- All versions above v1.1.0.0 do not accurately decode 6.1 DTS tracks with eac3to.
- 1.1.0.8 can't decode DTS(-HD) 6.1/6.0 but can decode non-standard 7.1
- Both decode DTS(-HD) 1.0 correctly, unlike 1.1.0.7.
lossy DTS
1) 1.1.0.0 and 1.1.0.1 always decode lossy DTS as 24 bit, and their decoding results differ from each other.
2) 1.1.0.5 and up decode in proper bitdepth.
3) Versions 1.1.0.5 and up decode lossy DTS identically.
4) 1.1.0.1 and 1.1.0.5 decode 24 bit lossy DTS identically.
5) Decoding of 16 bit lossy DTS was changed from 1.1.0.0 to 1.1.0.1 and from 1.1.0.1 to 1.1.0.5.
6) 1.1.0.7 and 1.1.0.8 decode 6.0 without back center channel.

The conclusion : for lossy DTS is 1.1.0.5. It decodes all configurations, in proper bitdepth, and decoding algorithm didn't change since this version (except 6.0 bug in .7 and .8).

Just to add to your list. I have 1.1.0.0, 1.1.0.5, 1.1.07, and 1.1.0.8. Only 1.1.0.8 seems to work with DTS MA 1.0 files. I don't know about 1.1.0.1 since I don't have it.

i don't know why the same wrong information is continue spreading, when there are enough facts proving that's completely wrong statement about 1.1.0.0 vs. 1.1.0.8 regarding non-standard 7.1 (i.e. "strange setup") tracks:

Is it the only one that can decode such files or what is the issue with other versions?

It's the only version that works that I know of.

I have 2 Blu-Ray discs with DTS MA 1.0 tracks. The Big Heat (1953) and The Big Trail (1930). 1.1.0.0, 1.1.0.5, and 1.1.07 give errors everytime I try to decode with eac3to. I also can't play the DTS MA 1.0 audio in TMT either unless 1.1.0.8 is in the codecs folder. I don't have version 1.1.0.1, so I can't comment on whether that version can decode DTS MA 1.0 or not.

Hi All,

I'm trying to convert this into a blu-ray structure ISO for playback on my media player.

I have no problems extracting all the files using either evodemux or HD-DVD steam extractor but cannot remux this particluar TrueHD track.

I've spent the past week trying to work out issues that exist with remuxing TrueHD tracks.

I tried to convert the TrueHD track to DTS but it comes up saying that it does not support the sampling rate.

Here's an ouput log:

I use evodemux to get the THD file but I can't do anything else with it. Tsmuxer bombs out saying it can't detect stream type so it can't read and import it

Eac3to cannot convert it to thd+ac3.

I've also used a program called pcm2tsmu which converted the TrueHD track to an LPCM stream sampled at 96KHz which tsmuxer was able to use and process. When I created a BD structure through Tsmuxer and played it through my media player, the audio cames out as white noise.

Is converting a TrueHD track to an LPCM stream going to be inferior in any way?

If anyone has this disc, can you please let me know if you had any luck successfully converting this to blu-ray with the TrueHD track intact.

Any help would be much appreciated.

Cheers

@pasadena
- With THD track: I don't know if this can work because I can't test with a THD 96 KHz, but try this:

"D:\Converter Programs\HdBrStreamExtractor_0.8\eac3to.exe" "D:\Black and White Night" 1) 4:"D:\bwnight\1_4_audio.thd+ac3" -resampleTo48000 -progressnumbers

- With DTS-MA: you can't use Surcode because don't support 96 KHz and DTS-MA, only standard DTS is not recommended.
If you have DTS-HD Master Audio you can extract the monowavs and after encode to DTS-MA

"D:\Converter Programs\HdBrStreamExtractor_0.8\eac3to.exe" "D:\Black and White Night" 1) 4:"D:\bwnight\1_4_audio.wavs" -progressnumbers

- With LPCM, same quality than THD but biger size.
You have two options:

1) Decode to w64 (tsMuxeR must accept PCM in w64 container):

"D:\Converter Programs\HdBrStreamExtractor_0.8\eac3to.exe" "D:\Black and White Night" 1) 4:"D:\bwnight\1_4_audio.w64" -progressnumbers

2) Decode to special PCM format for tsMuxeR with pcm2tsmu:

"D:\Converter Programs\HdBrStreamExtractor_0.8\eac3to.exe" "D:\Black and White Night" 1) 4: stdout.pcm -progressnumbers | "YOUR-PATH-TO\Pcm2Tsmu.exe" - "D:\bwnight\1_4_audio.pcm" -s 96000

@tebasuna51

Thanks for getting back to me.

I'll give these a try in the morning and let you know the outcome.

Much appreciated.

Cheers.

There will be any chance that eac3to become multithreaded?
