No NeroAudioDecoder cant connect with SonicHDDemuxer
Too bad!!

[ACrowley]

edit. SRY

NeroAudioDecoder2 "can" connect to SonicHDDemuxer 4.3.
But only to the EVO. not to the single mlp.
But when i select the TrueHD the graph fails

I made my own encodes in MLP 16bit 5.1
Playback in Zoomplayer with SonicHDDemuxer-SonicCinemasterAudioDecoder4.2 (4.3) works pervect without backround noise
In othe rDShow Players too.

But SonicHDDemxuer must have Propbmes cause the Runtime is always wrong. Must be 1min39sec ,but Runtime is 18h23min .
Runtime from SupermanReturns TrueHD in Zoomplayer is thousand of hours. Must be caused by Sonic
But Playback is clean

@madshi and @ACrowley

do you know how to distinct DirectShow filter from DMO? i'm asking this, because i think that Sonic decoder 4.3 is DMO and it's not DirectShow filter, because with both MLP and TrueHD there are a lot of "discontinuities" :

http://img528.imageshack.us/img528/8274/sonicdiscos3.png (http://imageshack.us)

and in text on msdn.microsoft.com i've read something like:

When a DMO, which was not designed to work in DirectShow, receives the DISCONTINUITY flag, it performs a flush and loses the data stored. To work around this issue, the best solution is probably to write a custom DMO Wrapper filter that does not set the DISCONTINUITY flag.

so maybe Sonic 4.3 is DMO and some buffer are flushed and thus from time to time random values are send on the filter output and that results in noise, it affects only the TrueHD implementation, because there are a lot of "discontinuities" when playing MLP too, but the sound is normal.

i don't know if there are any DMO wrapper DirectShow filters available, that can be tried with Sonic 4.3 filter or how to know for sure that it is DMO ...

[EDIT] using 'InterVideo Container DMO' connected to the output of Sonic audio 4.3 fixed the "discontinuities" errors, but sound still has noise ...

Too bad. It sounded promising... :(

eac3to 1.9 released:

http://madshi.net/eac3to.zip

Most important new features:
(1) multi channel mono wav output added
(2) automated SurCode DTS encoding added

Full list of changes:
(1) 24bit PCM handling works now (was buggy before)
(2) "-blu-ray" option removed
(3) with PCM input files "bigendian" is default now
(4) with 5.1 PCM input blu-ray style channel remapping is default now
(5) switches "-16" and "-24" are valid for both TrueHD and PCM input now
(6) eac3to now creates the WAV files on its own instead of using sox
(7) target extension ".wavs" results in one mono wav for each channel being created
(8) SurCode DVD DTS encoding automation added
(9) new options "-768" and "-1536" for DTS encoding
(10) TrueHD output is not downconverted to 16bit by default, anymore.
(11) new option "-down16" downconverts the raw data from 24 -> 16 bit (not limited to TrueHD input)
Due to the many changes I did to the code, some new bugs may appear. Please let me know about any problems you run into.

For Blu-Ray PCM you can now get multiple mono wavs or a DTS encoding simply by doing:

"eac3to source.pcm dest.wavs"
"eac3to source.pcm dest.dts"

No additional parameters are needed, unless eac3to fails to automatically detect the bitdepth. In that case you need to specify "-16" or "-24".

My apologies to The_Keymaker, cause he has to redo the option checkboxes so often...

[madshi]

I can say :eac3to fails (for me)on these 24bit lpcm
Fixed in eac3to 1.9. Thanks for the sample!

[honai]

@madshi

Great work, thank you so much for filling that request! Your dedication is very much appreciated!

[Beastie Boy]

Many thanks madshi, the mono wave output is just what I need.
The_Keymaker, over to you... :) :thanks:

Cheers, Beastie.

[ACrowley]

Fixed in eac3to 1.9. Thanks for the sample!


nice madhsi...i will try it:)

Otherwise i found a 100% working Method for any LPCM24 bit to whatever

Mono wave output is what i need so i can feed Steinberg Nuendo without a extra Step

great work!
@xskodi i dont know a DMO wrapper...
Yes, all my tested mlp sounds normal in any dshow Player. But in TrueHD theres still noise with Sonic 4.3 Decoder
However, Nero works so far

[crapz0rs]

I have surcode 1.0.2.3 installed, but the dts creating doesn't work.
Audio Decoder output was 24 bit this time.
Convert the multi channel raw file to mono wav files. Please wait...
Convert the mono wav files to dts. Please wait...
Creating the DTS file failed. The multi channel wav files are valid, though.
Encoding the 6 mono wavs in surcode works fine though :-)

@madshi

LPCM 24Bit to wave works now! nice...

But the flac Problem still exits for me

24Bit LPCM to 24Bit flac results in a flac which has the same Size as the raw! Strange...
On the Sample both 24Bit Files are 90MB
On a 6.7GB LPCM the FLAc from eac3to is 6.7GB too

I tried all combinations again on the same sample
So i use Audacity 1.3.3 to encode to flac 24bit

2 Questions:

1. Are you using Besiled 0.3 at the end of the dts chain to fix dts output? I think so...
Maybe you can remember, we talked about via PN

eact3to dts encode works with all 16 and 24bit Sources

2. Whne i convert a lpcm.raw to wave with -Bluray, the Message "remapping channes" will not longer appear ?
Output wave has correct channelmapping

[honai]

Besliced 0.3 at the end of the dts chain to fix dts output

What exactly is happening at this step? How is the DTS stream from Surcode erroneous?

[madshi]

But the flac Problem still exits for me

24Bit LPCM to 24Bit flac results in a flac which has the same Size as the raw! Strange...
On the Sample both 24Bit Files are 90MB
On a 6.7GB LPCM the FLAc from eac3to is 6.7GB too
I'll check that. Maybe I'll switch to the flake encoder. Maybe that won't have problems with > 2GB output. Don't know...

1. Are you using Besiled 0.3 at the end of the dts chain to fix dts output?
No, I found a better way... :) There's a registry value which tells SurCode to give out a more compatible DTS stream (named "PAD ZEROS"). Unfortunately SurCode keeps on resetting this registry value to the "bad" setting all the time, so it's very uncomfortable for manual use. Of course eac3to solves all these troubles for you.

eact3to dts encode works with all 16 and 24bit Sources
I had to replace sox to make that work. SurCode didn't like the 24bit WAV files produced by sox. So now eac3to doesn't use sox for WAV file creation, anymore, but does that work itself. The WAV files created by eac3to should be similar to what wavwizard outputs. They seem to be more compatible then what sox creates.

2. Whne i convert a lpcm.raw to wave with -Bluray, the Message "remapping channes" will not longer appear ?
Output wave has correct channelmapping
The message doesn't appear, anymore, because I'm now doing that step together with some other steps like creating mono wavs etc. In the older eac3to build the channel remapping was a separate step. In the new build eac3to is sometimes doing multiple steps at once to save time. You may have noticed (or maybe not) that the LPCM -> mono WAV conversion is rather quick. It should be 2x-3x as fast as before.

[madshi]

What exactly is happening at this step? How is the DTS stream from Surcode erroneous?
Older versions of SurCode (the latest version 1.0.29 doesn't have this problem) by default added some zero bytes after each DTS frame. A normal DTS frame for 1536kbit/s is 2013 bytes long. SurCode by default writes 2013 real bytes and then 35 zero bytes for every frame. Don't ask me why they're doing that, I've no idea. delaycut, besplit and most other software doesn't like this very much. Fortunately, I've found a way to convince SurCode to stop adding those 35 zero bytes after each DTS frame and added that to eac3to.

[ACrowley]

Madshi is right
With a Surcode encoded dts you will get these Errors in the Header and mostly wrong Runtime/Filesize and this Error in mkvmerge :

audio/video go out of sync, but this stream is damaged.
Warning: dts_packetizer: skipping 35 bytes (no valid DTS header found).
This might make audio/video go out of sync, but this stream is damaged.

To fix the dts you can also use Besliced.exe (0.3)

Besliced 0.3 exe included in :
http://dspguru.notrace.dk/BeSplitv0.9b6.zip

Simply open Besliced.exe and move your dts into the window and select fix.
You will get a lot of Errors in the Log like this :

@Madshi
1 .The Surcode Registry Key "PAD ZEROS"). it should be set to 0 ,right ?

2. When i use -down16 on the sample, the flac output still has the loud noise
.wav output is ok (in 16 and 24bit)
And -flac in 24bit ,has the Filesize Problem i told you above

3.Flake encoder would be nice. Its faster und higher -12 compression
But :
At the Moment you get only 16bit flac from flake encoder :
Signed 24-bit 48000 Hz 6-channel
WARNING! converting to 16-bit (not lossless)

http://forum.doom9.org/showthread.php?t=120871

Hi,
I wrote Flake. 24-bit encoding is on the TODO list, but right now does downsample to 16-bit. As far as Winamp crashing...that's really odd. It should not be doing that, especially with the settings you used, which do not utilize any of Flake's experimental stuff. My guess is that the issue is Winamp since Foobar decodes okay. But then again, Flake has not been through very vigorous testing at early this stage in its existance.

Anyway, it seems that your only choice for now to encode 24-bit is the libFLAC encoder...I just wanted to chime in and say that I'm working on adding it to Flake sometime in the future.

[The_Keymaker]

New version (v1.15) of EAC3toGUI available here:

http://www.sendspace.com/file/ltxl6s

Changelog Version 1.15:
- Added DTS rate options
- Added Down convert option "-down16"
- Added "wavs" and "dts" filemasks
- Changed PCM and TrueHD options scheme to allow selection of common options (16bit, 24bit, 96Khz, 8ch)

Please report bugs, suggestions and overall usage experience.

Regards,
The_Keymaker

[honai]

A normal DTS frame for 1536kbit/s is 2013 bytes long. SurCode by default writes 2013 real bytes and then 35 zero bytes for every frame. Don't ask me why they're doing that, I've no idea.

Probably to get to the "magic" 2048 bytes size. I'm not sure but I think that DTS over SPDIF gets wrapped/padded in such a way, too, though transparently by the soundcard driver or AC3Filter.

[ACrowley]

@The_Keymaker

BluRay channelmapping Switch is removed cause eac3to will do it autom. now ,right ?

Little Suggestions

1. I know in your opinion (youre right) its enough to type in the dest. File extension to set Output Format.
But ,imho, a small scrolldown Outputformat Window would be nice

2. The Downconvert Option would be more obvious with "Downconvert to 16Bit"

3. Maybe a little Error ? When you select "Browse" to set the Output, the Windows Name is "Select the Source File" , shouldnt it be "Save as" ?
And Filetyp is (ac3,raw,wav), Theres no flac ( ac3,raw,wav,flac)

4. And the Input Extension .raw would be nice

Ofcourse its all marginal, your Gui works great! THX

greets

[The_Keymaker]

@Prophecy650,

as far as I can see from the "The Break-Up" HD DVD specs, this HD DVD doesn't have a TrueHD track, but only some E-AC3 tracks. So you may want to try demuxing the E-AC3 track by using EvoDemux and then feed that into eac3to. Maybe that works better?

how do I get it to ac3 now? thanks alot madshi, I can hear the audio atleast now

[madshi]

Looks like an Aften crash to me. Can you please try a different Aften build? I'm using one from here:

http://win32builds.sourceforge.net/aften/index.html

Don't remember which one. Might be revision 449.

[Prophecy650]

the file is 5gb+ and the audio only like 23 min?

[madshi]

Which file is 5GB? The raw/wav file can be that big. But don't worry, the final AC3 file will be much much smaller. The raw/wav files are just temporary intermediate files. They're so big because they're totally uncompressed. AC3 is a strong compressing algorithm.

[Prophecy650]

madshi I love you lol, got it to work with the 449 like u said, thanks a million

Hello madshi.
Is it possible to add parameter for working directory? Because it is not best idea to create mono wavs in same directory where source eac3/pcm file is located.
Thanks in advance

[tebasuna51]

whats the difference between using aften builds VERSION 0.07 and SVN REVISION 449.

The rev449 is a intermediate version between v0.06 (with problems with big files) and v0.07 (rev493).

I don't know problems with Wisodev v0.07 compiles, please report if the problems related in this thread was with Aften v0.07 or a previous one.

With rev449 some of the changes in v0.07 (http://forum.doom9.org/showthread.php?p=993727#post993727) may not be present.

Edit: The rev449 is the first using the parameter -readtoeof 1 to support wav files >4GB. See this post (http://forum.doom9.org/showthread.php?p=961856#post961856) and following.

Because it slows encoding down :)

When you start SurCode manually, what does the title bar say? Does it say "DTS Encoder" or something else? Does the encode button say "Encode" or something else? eac3to depends on these texts.

You don't have accidently deleted the "HookSurcode.dll" file which comes with eac3to? Cause that file is needed for SurCode automation.
