eac3to - audio conversion tool

[Falcon4]

Well, without the help of this thread, and with the marginal help of Google (pointing me to a package), I solved the problem and eac3to is now happily crunching away my audio.

The problem was that my DTS/AC3/DD+ Source DirectShow filter was corrupted - specifically, it was registered to a file that was in my "temp" folder and got deleted. I wonder who did that (no, really - I doubt it was eac3to). I also found a slew of other odd filters and plugins that no longer existed and were causing problems. Ironically enough, the K-Lite Codec Pack installer had a neat utility, the Codec Tweak Tool, that was able to detect and repair these problems. It also had a working copy of the DTS/AC3/DD+ Source tool.

So by downloading the K-Lite Codec Pack, setting it to full Custom (deselect all), choosing only the DTS/AC3 Source filter and the Codec Tweak Tool, then running the Codec Tweak Tool to scan for broken filters, I ended up solving the problem.

It sure is taking a while to decode that 30mb audio clip though... o_O

So hey. Thanks to the author of eac3to for creating it, and no thanks to the fine members of this forum for pointing out the obvious.

Software authors should be expected to provide their bits of code for free.
Sure. Shame on every software author who dares to make a living. Of course all software authors were borne with an unlimited and neverending debt to the community. They rightfully owe their lifetime's work to the general public. That's a binding curse which must be the direct consequence of misdeeds in their previous lifes.

Oh wait! I don't believe in reincarnation! Hmmm... :confused:

Congratulations for post #1000, madshi. I admire your neverending patience. ;)

I am using eac3to 2.03 and I'm trying to convert a DTS-HD track to AC3. However, the process just freezes and never finishes. I read about similar problems a few pages earlier in this thread, and they were resolved with v2.01, but I still have this problem.

Any ideas?

Here's the output:

As I kinda hinted at in my last post, mine locked up too (requiring a Ctrl+C). Turned out that xport.exe split out a botched up audio stream somehow, but a quick "eac3to ... -core" output a corrected file, which decoded properly into a mixed-up WAV file (like I asked it to) the second run-around. So my suggestion would be to do -core on it first, then decode it. Hope it helps! :)

Yeah, thanks. Worked out well to get the DTS core and then transcode the DTS to AC3 :)

Hi there, thanks for this unique program first of all :)

Thanks in advance for any help, Rob

No time yet. Will have time on Sunday, I think...OK, i hope you rest a little bit. You deserve it.

[menlvd]

and how about dts-hd 7.1 any chance to get worked in future?
i think dts-hd 7.1 have same as dts-hd 5.1 core of dts 1536 kbps
when i play the m2ts file Nero audio 2 showing that

Hi there, thanks for this unique program first of all

been having success with DTS\DTSHD tracks but EAC3 isn't working for me....

I get this message....

To update my previous post, I tried doing the same conversion with an older version of EAC3TO, to see what happened and it came up with this error instead of the previous one (that was using the latest version of EAC3TO

[nautilus7]

How much free space do you have on your hdd? But i don't think the new eac3to needs lots of it...

[hristoff2]

mmm missing dump filter?
- http://uploaded.to/?id=v40yi1

(obviously everything but writing/dumping the file works, as stated by the log)

[nautilus7]

eac3to 2.xx version doesn't need dump filter. madshi wrote his own filter for this purpose.

[Furiousflea]

How much free space do you have on your hdd? But i don't think the new eac3to needs lots of it...

Hi, Over a 70GB of space on the HD remaining so defo aint to do with that, for the old version dump.ax was "successfully registered".

?:( thanx

[nautilus7]

I think we all have to wait till Sunday. Madshi will fix our "issues" then.

[madshi]

I have a problematic eac3 track.
I am triyng to convert it to ac3 and eac3to stops saying that i should use delaycut to clean the track.
I load the eac3 track to the latest version of delaycut that supports eac3 and it recognize 2 frames as problematic and drops them whatever mode i choose (fix, ignore, silence). Is there a bug there?
I've checked. It's intended behaviour. The problem is that there's not a CRC error in those 2 frames. Instead there's not even a valid header for those frames. So delaycut doesn't know what to do and sees no other chance than to skip forward to the next valid header. delaycut was implemented to behave this way. Those modes work only if the header (actually only the first 2 bytes!) is valid.

in the ac3 bitrate options you don't mention 384 kbps.
There are many more supported bitrates which I didn't mention. I don't flood the help with every single supported bitrate, so I've only listed the most common ones.

i tested the open source MLP/TrueHD decoder with "V for Vendetta" MLP track and the output is byte by byte identical to the output of eac3to 2.x, with previous eac3to 1.23 the output was different, but that was because of the first 4 bytes cut issue, so that is a huge prove for both eac3to and the open-source MLP/TrueHD decoder, because they use so different approaches and produce the same output.
Interesting! I couldn't get the open source TrueHD decoder to work, but it seems that I did something wrong.

try to reencode dts-hd and got that

D:\minep\me_gui\tools\eac3_to>eac3to.exe i:\hair.dtshd g:\hair.ac3
DTS Hi-Res, 5.1 channels, 5:44:36, 24 bits, 1914kbit/s, 48khz
Decoding with DirectShow (Sonic Audio Decoder)...

but its only 1:56:06. From hairspay BD movie
That's an interesting track! There's a new flag combination in the DTS-HD header which eac3to didn't know yet. It got interpreted as DTS Hi-Res while actually it's DTS Master Audio 7.1. I've added support for this in the latest eac3to build.

[madshi]

with a bit luck the next version might feature nice 7.1 truehd and dts-hd support ;)
Unfortunately I'm limited by what the decoders support. The Nero TrueHD decoder doesn't support 7.1 decoding. And the Sonic Audio Decoder seems to decode only 6.1, but not 7.1. With that Hairspray 7.1 DTS-HD Master Audio track Sonic only outputs 5.1, sadly. Once the open source TrueHD decoder is ready to roll, we might get 7.1 TrueHD decoding, at least.

I'm having problems converting E-AC3 to AC3. The source is Black Snake Moan from HD DVD. I'm using Nero decoders.

Basically, it starts to decode the E-AC3, but never starts encoding with Aften - so I get no output file.


eac3.exe "i:\feature.ddp" "feature.ac3"


Running Vista x64... latest version of eac3to and Nero 7.
I can only guess that this is caused by eac3to using dirty hacks which might not work that well in Vista64. Please try the next eac3to build. I've replaced the dirty hacks with a cleaner approach. That might work in Vista64.

[madshi]

eac3to crashes when trying input.thd output.wavs with nero filters.
Fixed in next build.

[madshi]

The real file size is 0 Bytes.
There seems to be something wrong with your Nero installation. I'd suggest that you uninstall and reinstall Nero from scratch. If that still doesn't work please contact Nero support.

thanks for the next update :)

just to clarify again, truehd 7.1 input isnt supported at all currently and dts-hd ma is, but the outcome will be 5.1?

Everything is supported. But output is sometimes only 5.1.

[Thunderbolt8]

is it actually possible that the TrueHD track from a clockwork orange is only a 16-bit track, despite whats said everywhere? I encoded it to flac with this version, the former version and also with 1.23 and each time the rest 8-bit were only zero information bits.

Sure it's possible. How big is the TrueHD file and what is the runtime?

[shambles]

the new version fixes the problem i had.. thank you so much :)

Definitely 16 bit.

eac3to v2.05 released

http://madshi.net/eac3to.zip

* added support for libav/ffmpeg decoding of TrueHD/MLP and E-AC3
* added "-libav" switch to force libav decoding
The libav TrueHD decoder seems to work well. In my quick tests it gave out bit perfect results compared to Nero's decoder. However, with a 24bit TrueHD sample the libav decoder complained about a failing "lossless check". Still the data was bit perfect. But the complaint shows that it might still make sense to keep using the Nero TrueHD decoder for a while - at least for comparison purposes. However, we might have a chance to get 7.1 TrueHD decoding now with the libav decoder. Does anybody have a sample of a 7.1 TrueHD track?

The libav E-AC3 decoder is not useable yet IMHO. It sometimes gives out distorted sound for me. I've still enabled it so that you can play with it, if you like. Another problem of the libav E-AC3 decoder is that it always forcefully shortens the data to 16 bit.

Unfortunately it's not 7.1 but only 5.1... :(

ew really? according to evodemux or the real data inside?
maybe its not possible for evodemux to demux or display the tracks properties properly? maybe pelican9 needs to update :S

this is what evodemux says:

mainwindow:
Dolby TrueHD audio stream 1 found!
First PTS = 000053C3 (+200ms)
Substream id = B1
TrueHD stream (up to 8 channels)
Sampling frequency = 48 kHz
2 ch. decoder
channel modifier = Stereo
6 ch. decoder
channel modifier = Lt/Rt
channel arrangement = Main (Left,Right), Centre, LFE, Surrounds (Ls/Rs)
8 ch. decoder
channel modifier = Lt/Rt
channel arrangement = Main (Left,Right), Centre, LFE, Surrounds (Ls/Rs)
Dynamic range control = -10,6371 dB .. 8,4282 dB


VTI:

Afaik 24 bit output is not supported in libav, but it could be put in 32 bit. Did you get that working?

Kurtnoise13 couldn't get it to work in ffmpegsource: http://www.mediafire.com/?1we0uonvjm0

[Thunderbolt8]

32-bit should be really big I guess :S

[nautilus7]

So, is there anything i can do? Can i fix the header?

Thanks for the nice updates you 've made!

[Blue_MiSfit]

Confirmed. Using ffmpeg to decode EAC3 I get all sorts of nasty high frequency artifacts. Not good! :)

I hope this matures!

Where does EvoDemux say that it's a 7.1 track? The 8 channel decoder settings say "Main, Centre, LFE, Surrounds" which is 5.1. So it's a 5.1 track.

I got 32 bit output working (only from the TrueHD decoder, not from the E-AC3 decoder) and internally converted it down to 24 bit. That gives me bit perfect results compared to Nero's decoder for both 16 bit and 24 bit TrueHD tracks.

[madshi]

32-bit should be really big I guess :S
Well, there's only 24 bits of real data (or even only 16 bits), so those 32 bit can be cut down to 24 bit without any loss of "real" data. And that's what eac3to does with the output of the libav TrueHD decoder.

[madshi]

So, is there anything i can do? Can i fix the header?
Well, you could check the frame size (in bytes) in delaycut. Then with a hex editor you can search for the frame where the first two bytes of the frame are not correct and manually correct them. Of course this only works if the "garbage" in your track is exactly one frame long. If it's real added garbage, it'd be better to skip that data. If it's not real garbage, but just a corrupted frame then it might be better to silence the frame.

Hello Madshi,

thanks for your great tool. I have only one question, option -bluray is needed alway when i use as source PCM file xported from BluRay Disk? Because remember that option was in some early version of EAC3 tool but then it dissapeared and was done automatically. Now it is again manual and nothing is done automatically?

Good question. I should have explained it.

eac3to doesn't really know (and has no way to find out) in which order the channels are, if you feed it with a RAW or PCM file. The previous eac3to version made it simple: RAW input files were not supported. Only PCM files (files with the extension "pcm") were supported. Basically eac3to interpreted any PCM file input as being Blu-Ray and thus automatically remapped the channels accordingly.

But now the new eac3to version supports both PCM and RAW files (which are really one and the same). It's impossible to know whether the file came from Blu-Ray or not. So it's also impossible to know whether the channels need to be remapped or not. eac3to v2.x now does an educated guess: PCM tracks from Blu-Ray are usually big endian. RAW tracks decoded from any DirectShow (or other) decoder are usually little endian. So eac3to v2.x handles big endian RAW/PCM files as coming from Blu-Ray and little endian RAW/PCM files as not coming from Blu-Ray. As a result channels are remapped according to Blu-Ray specs when the source file is big endian. And channels are NOT remapped at all when the source file is little endian. If the channels are remapped eac3to v2.x sais so (something like "this is probably a Blu-Ray PCM file, so I'll remap the channels").

If you demux Blu-Ray (L)PCM tracks with either xport or TsRemux the demuxed files will be big endian. In this case you don't need to tell eac3to anything. Just call it as usual with "eac3to source.pcm dest.whatever" and the channels will be automatically remapped correctly. However, if you demux Blu-Ray (L)PCM tracks by using GraphEdit -> SomeSplitter -> Dump, the resulting file will be little endian. As a result eac3to will think that this file is not coming from Blu-Ray. In this case you can use the reintroduced switch "-blu-ray" to force eac3to to remap the channels. But you need to be cautious: The DirectShow splitter might already have remapped the channels - or not.

Short version: If you use xport or TsRemux for demuxing Blu-Ray (L)PCM tracks, you don't need the "-blu-ray" switch. eac3to v2.x will still automatically remap the channels correctly for you.
