I recommend to redirect the eac3to help to a file, and load the file in a good text editor to remove the BS characters. Due to the extremely bizarre formatting options of eac3to, it's the only method that gives good results.

@ Brazil2: But this still lets CMD interpret the commands.

I had the feeling that's what XadoX wanted: to go back to CMD.

I have very little experience with PowerShell, but I believe it can on its own, yes.
Cmd on the other hand doesn't have a replace-tool, so you'd have to use 3rd party software.
My favorite:
Code:
eac3to.exe | xidel.exe -s - -e "replace($raw,'[\b]','','!')" | clip
or
eac3to.exe | xidel.exe -s - -e "replace($raw,'\x08','','!')" | clip
Or Cygwin's sed.exe:
Code:
eac3to.exe | sed.exe "s/\x08//g" | clip

Hi, I was under the impression that when converting a 7.1 track to 5.1, eac3to would automatically run a second pass and reduce the volume if clipping was detected. So I just ran this conversion and eac3to didn't generate a second pass. As a test, I ran the same command with -normalize added, and eac3to applied a -0.09db gain, so in other words, there was clipping. So am I supposed to add -normalize to every 7.1 to 5.1 downmix?

I can't tell you for sure, but I guess there may be circumstances where eac3to will only extract a 5.1 core and simply omit additional channels. Or it was just matrix encoded, no discrete 7.1 source anyway. You will have to specify more precisely which source format you have and which parameter set you used.

Source was DTS-HD MA 7.1 (Zootopia). I just used the stream extractor gui for eac3to, selected the audio track and selected AC3 for output (which would default to a 5.1 640kbps output). The log in both cases say the additional channels were mixed into the surround channels.

In this case, I guess a conservative fixed downmix gain was used. Ensures no clipping, but may not utilize the whole amplitude range. Correct me if I'm wrong...

I just ran the same tests on a completely different movie (but still DTS-HD MA 7.1), and again no messages about clipping. The second test with -normalize added, eac3to again applied a -0.09 gain.

So I guess eac3to just applies a standard -0.09 gain when downmixing 7.1 to 5.1 when the -normalize switch is used, and no clipping is detected?

So now of course I'm wondering, is using the -normalize switch good practice, or should I just let eac3to mix the surrounds and only automatically normalize if there is detected clipping?

A -0.09db gain can be considered like clipping, because LigH is right when say:

Is not recommended.

Even, if the automatic normalize show a big attenuation value, you can consider use a special downmix (MeGUI or BeHappy) than preserve volume in FL,FR,FC and LFE, and only apply attenuation to mix SL+BL, SR+BR.

Hi, what's the command to disable the notification 'boink' sound? If you run some batch file with 10 encodes, it boinks 10 times for each which drives me crazy while wearing headphones.

You can delete the WAV file.
it doesn't crash if there's no WAV file.

That is, I don't believe there is a "command" to disable the notification. It's just designed that way.

Hence: Delete the WAV file in the eac3to folder.
No WAV file, no sound.
It doesn't break anything if you delete it.

Try looking inside the folder with eac3to, or whatever GUI/AiO you are using and delete the WAV files.
They're not really needed.

I do that right away, after the first success sound reminds me I rename the wavs to nos. It is actually a nice and easy way to configure that feature.
