Aften 0.0.8 is out

[TFM_TheMask]

Try http://code.google.com/p/wavtoac3encoder/

[video_magic]

Please note:

http://sourceforge.net/projects/win32builds/files/


And http://kurtnoise.free.fr is just as dead.

So - where is a really "current" alternative?


Oops, I meant that is current as in it doesn't give a '404 page', but the builds are quite old you are right.

[tebasuna51]

In http://code.google.com/p/wavtoac3encoder/downloads/list the aften-git-20091226-icl11_1_054 is the last build I know.

[wisodev]

Version 4.6 and later 4.7 of WAV to AC3 Encoder have been released today:

Changes:
- Fixed: Issue 5: Importing .mux files in ANSI not possible
- Added support for avisynth in AMD64 (64-bit) builds using http://code.google.com/p/avisynth64/.

Downloads:

THANK YOU, Wisodev! I always look forward to updates for WAVtoAC3Enc!!! It's a tool in my kit that I use regularly!

[MrVideo]

Version 4.6 and later 4.7 of WAV to AC3 Encoder have been released today

OK, what does this program do that aften doesn't?

I got an e-mail that showed a response that you gave to my query, yet it appears that the response was deleted.

All of my audio work is done via the CLI, in scripts that I have written to automate the process of stuff that I do.

Its GUI version.

All of my audio work is done via the CLI, in scripts that I have written to automate the process of stuff that I do.

But my GUI has other goal then CLI version:
- It has optimized aften builds.
- Supports Avisynth scripts under Win32 and x64 OS.
- Can be used to automate several jobs from command-line using presets.
- Has MUX wizard.
- Supports unicode file names.
- You can access all aften options in one place and tweak quickly.

[MrVideo]

But my GUI has other goal then CLI version

Thanks for the info.

Silly me, I should have also followed the link in you signature.

Hello wisodev!

Is the project dead?
The site on google don't work anymore.

Too bad AviSynth input still does not work properly.

That works in BeHappy and MeGUI (which uses the engine derived from BeHappy).

Yes, the site seems to work again. He probably reactivated it or something.

Does anyone know why AC3 files encoded with Aften are not showing any information in MediaInfo ?

But it's gone again once the track has been extracted from the MP4.
However the files created by Aften are playing fine with Foobar and VLC.

Is it an Aften issue or a MediaInfo issue ? Any thoughts ?

[Kurtnoise]

but I got the same results in a command line box, with these parameters:
-readtoeof 1 -pad 0 -exps 32 -s 1 -b 448 - %d

why are you using -pad 0 -exps 32 -s 1 ? try without these switches...

[jruggle]

...

My guess is MediaInfo since you say the files play correctly.

Just for kicks, add '-xbsi1 1' to your commandline and see if that changes what MediaInfo prints out.

[jruggle]

why are you using -pad 0 -exps 32 -s 1 ? try without these switches...
'-s 1' should not cause any issues since the block switch flags are in the audio blocks, not in the frame header. '-pad 0' would have no effect on this since it only changes how source audio data is passed to libaften. '-exps 32' should definitely not have any effect on this since it's just an algorithmic decision option.

The only thing I can think of right off-hand is that maybe MediaInfo expects the extended bitstream format. That is what most commercial AC-3 encoders produce, but it is certainly not required. Aften only uses it if one of the extended metadata options is set.

[Brazil2]

why are you using -pad 0 -exps 32 -s 1 ?
Because of this:
To convert a wav file 5.0 you can use WavToAc3Enc or eac3to with external Aften.exe encoder:

eac3to source50 stdout.wav | Aften -pad 0 -readtoeof 1 -exps 32 -s 1 -b 640 - output.ac3

where:
-exps 32 -s 1 -b 640
is the best quality (and slow encode) than Aften can offer.



try without these switches...
It's the same.



Just for kicks, add '-xbsi1 1' to your commandline and see if that changes what MediaInfo prints out.
No change either.

[jruggle]

It's the same.
...
No change either.
Hmm...not sure then. I am unable to reproduce the issue in Linux with MediaInfo v0.7.16. I get normal output. Could you provide a small sample?

[Brazil2]

I think I've found out the issue: it only happens when the source file is not 48 KHz. As I'm not doing any sampling rate conversion I ended up with a 44.1 KHz file which doesn't show any information in MediaInfo.

But all of the tests I've done with the resulting files at 48 KHz are showing detailed information in MediaInfo. And BTW same goes for AC3 files created with ffmpeg so there are chances it's a MediaInfo issue.

That's odd. I thought at one point that might be the cause, but 44.1kHz files also work fine for me with MediaInfo v0.7.16.

[tebasuna51]

Because of this:
...
-exps 32 -s 1 -b 640
...

Then for what you put: -exps 32 -s 1 -b 448 ?

Let the defaults for -b 448

No problem with AC3 streams, maybe a MediaInfo bug like put:
Bit depth : 16 bits
Lossy compressed streams don't have Bit depth, and we can't know the bitdepth of the source, can be 16, 24, 32, ... bits

@jruggle, please a new version with last improvements.

[Brazil2]

Weird, I got it working with some 44.1 KHz files but not with some other ones.
I've uploaded some samples here: http://www.multiupload.com/9Z1X01V9FF

Two of them are working fine with MediaInfo but the third one doesn't.

@jruggle, please a new version with last improvements.
I don't really have time for a release right now. I'm very busy improving the (E-)AC3 encoder in Libav. It's better than Aften now, and I will most likely no longer do additional improvements to Aften other than bug fixes.

Which tool are you using that gives this information ?

[Zenitram]

I think I've found out the issue: it only happens when the source file is not 48 KHz.

You're right: there was a bug in MediaInfo preventing analysis of some non-48 KHz file.

That's odd. I thought at one point that might be the cause, but 44.1kHz files also work fine for me with MediaInfo v0.7.16.

I added CRC check in newest versions, and this piece of code was buggy with non-48 KHz streams.

Corrected in latest development snapshot (https://sourceforge.net/projects/mediainfo/files).

@ tebasuna51:

is it possible that this tool could be used to patch an existing ac3 with data (such as DRC values) from another?

i suppose we'd have to guarantee the blocks are all aligned and all that, or is DRC frame based?

here's where i regret not learning C when i had time back in the day. it doesn't seem fair to ask for stuff without contributing something (or at least doing it myself from the source).

[tebasuna51]

Yes each frame must have the same length and we can't insert data into a frame.

We can replace something like Dialog Normalization, the flag about Dolby ProLogic, ... and after recalculate the CRC's of the frame.

But we can't insert new data.

[xabregas]

Is there a way to cutoff frequency to lets say 80HZ and add more bass to audio??

[LigH]

Filtering and mixing audio is not the duty of an encoder, at least not to change the sound to personal preferences of a single listener, instead it should try to reproduce the sound with as little distortion as possible. But there is the exception of quality optimization (this is the mentioned "cutoff" of hardly noticable highest frequencies, usually above 12...16 kHz, which mostly disturb the encoding quality) and preparation of content with a specific purpose. The LFE channel would be designed to contain low frequencies only; but is intentionally named "Low Frequency Effects: It is usually not meant to contain only the filtered low frequencies of already existing full spectrum channels, but rather additional effects (especially regarding audio of cinematic movies). You may use the LFE mixdown to add existing low frequencies of present channels into the LFE channel; but it is (AFAIR) not intended to serve this purpose only.

[tebasuna51]

The cutoff frequency is for cut high frequencies, like LigH say, and is related with bitrate because save high frequencies need much more bitrate.

The low frequencies don't need be cut because don't need much bitrate, and always is saved like original without changes.

BTW please remember than Aften encoder is deprecated and replaced with ffmpeg (https://forum.doom9.org/showthread.php?p=1522077#post1522077) (supported by jruggle) encoder.

[xabregas]

Thanks for the answers but i didnt explained the reasons behind why i wanted to do this.

As you might all be aware now amazon streams come with the new Dolby Digital Plus aka E-AC3. At first i tought i would get better audio and stopped purchasing itunes and started buying amazon. But the problem is i didnt get better. My soundcard can decode only AC3 and DTS. So i can`t seem to send E-AC3 trough spdif. I solved the issue at first by doing real time ac3 encoding of E-AC3 and sending through spdif and it worked but the audio was all wrong. Too strong on explosions and voices too low even with DDR enabled and sometimes the voices come strong and wrong mapped. I went to Amazon foruns asking if they could provide AC3 stream for all the episodes but they dont seem to be interested in doing that.

So how can i encode E-AC3 real time or not to AC3 and get the usual quality i was used to when i used the itunes audio? Or do i need to purchase every episode i already got from amazon on itunes just to have proper audio sending through?? I tought cutting off high frquencies and making dialogue normalizer to -31 would solve this? But aften only accept wav streams. How do i decode e-ac3 stream to wav the right way?

Thanks

[tebasuna51]

Like I say before forget Aften.exe

You can recode directly EAC3 to AC3 with ffmpeg with a batch file like:

rem Modify next line with the path to ffmpeg in your system
set FFMPEG=D:\Programa\Audio\0\ffmpeg
FOR %%I in (*.eac3) DO "%FFMPEG%" -drc_scale 0 -i "%%I" -acodec ac3 -ac 6 -ab 448k -center_mixlev 0.707 "%%I_.ac3"
pause

All eac3 in folder are converted to ac3 at bitrate selected (here 448 Kb/s)

[xabregas]

I am a bit noob to work with what you gave me but after testing many times and changing the paths i got it to work. Turns out the problem was in the .eac3. It worked with .ec3. :D

Thanks!!!
