madshi should set up an autobuilder

for eac3to.zip, duly in sync with the latest ffmpeg of course

Or maybe it's simply time for a new release, compiled against the latest libav/ffmpeg!?

Seriously, I don't have the Windoze environment to compile C sources.

It most certainly is!

Kurtnoise · 20th October 2011, 13:21

did you try to grab the dlls from the shared build and put them in the eac3to folder ?

mbcd · 20th October 2011, 17:03

I thought that eac3to supports plugins, isnt it possible to build a plugin that fixes some problems as channelorder, thd, ... ?

Otherwise, for what could someone use those plugins-interface ?

channel.SR.wav -> "beep… back right"
channel.BL.wav -> "beep… side left"
channel.BR.wav -> "beep… side right"

I can confirm that, just tested it out on DTS-HD Master Audio 7.1 24bit, 48kHz.

S* = Back
B* = Side

which channel configurations does down2 work on?
5.1 and 7.1 seem to work, but between 2.0 and 5.1, does anything work?

tebasuna51 · 21st October 2011, 15:18

To 2.0 -> 5.1 read the Sticky: GUIDE LIST: Stereo-to-Surround Conversion Guides

I think he asked about situation of down-mix to stereo from multi-channel sources with non-standard number of channels, such like 2.1 / 3.0 / 4.0 / 5.0.
At least that's how I understood the wording "between 2.0 and 5.1" of his post's context.

mindbomb · 21st October 2011, 23:11

yea, kypec is right.
maybe i should have been more clear.

If you try to use down2 on 3 channel audio, it just doesnt work, is that right?

tebasuna51 · 22nd October 2011, 03:27

Sorry.
Only work with 5.1, to downmix 3, 4 or 5 channels to stereo use MeGUI.

Is it possible to output 32 bit audio to stdout?

For 24 bit I use:
eac3to.exe in.mp2 stdout.pcm -24

"eac3to.exe in.mp2 stdout.pcm -32" doesn't seem to give 32 bit audio (it isn't in the docs so no surprise) but is there a way?

ramicio · 29th October 2011, 05:03

Use the -full switch to get 64-bit floating point. It's either 24-bit integer or 64-bit float, nothing in between. What is even going to accept 32 float as an input? What is the point? It offers the same precision as 24-bit integer if nothing goes over 0dB.

Asmodian · 29th October 2011, 07:09

Thanks, it makes a lot more sense now.

It turns out I am just getting 24 bit from the eac3to, there are no more bits to get. (-full gives 24 bit)

I am piping to qaac, I think 24 bit is all that exist for this mp2 source but qaac could take 32bit float if it did exist.

So there is no point.

Hello,

I think a found a little bug:

With this command line:

"C:\MasProgramas\eac3to\eac3to.exe" "C:\Temp\VideoSynch\Vsy_Segmento_Aud_000.ac3" "C:\Temp\VideoSynch\Vsy_Segmento_Aud_000_sil001.ac3" -silence -edit=0:00:00.544,1088ms

Eac3to shows a error:

Invalid edit format "edit=0:00:00.544,1088ms

And also with: -edit=0:00:00.544,544ms

but not with: -edit=0:00:00.544,543ms

If the silence duration to insert, is bigger than the insertion position, eac3to trows a error. So:

-edit=0:00:00.789,800 is a error
-edit=0:00:00.789,788 is not

I think is a easy fix (an outdated check in action, I think). Is the source code available?

Thunderbolt8 · 30th October 2011, 23:07

nope

Atlantis · 31st October 2011, 03:57

Guys this is a long thread but please excuse me I couldn't read it all.

I have noticed that eac3to can not read a 32bit float wav file created by audition as input. If I convert the same file in audition to 24bit, eac3to can read it. Any ideas?

I can't reproduce your problem.
Please put a sample (1 second is enough).

far.in.out · 31st October 2011, 19:40

Hi. I'm doing

Code:

eac3to input.dtshd output.flac -down2 -mixlfe -down16

and getting this in log

Code:

Clipping detected, a 2nd pass will be necessary.  <WARNING>
...
Applying -6,73dB gain...

So, should I worry about it?
Should I redo it using like -7dB to be safe?
Or is it fine after second pass?
Does it use the source dtshd for 2nd pass or just created flac?

No, no, yes and temporary wav I guess.
