Hello, madshi!
First of all, big THANK YOU for eac3to, especially for support and update this great program!
And I'd like to ask you one question: why you didn't add azid.dll to eac3to? There is some troubles to decode DD, because you have to demux DD with eac3to and decode it with azid or nicaudio for correctly decoding DD. You know, nero don't ignore DRC and libav downturn of high frequencies after 17 kHz. You can see (E-)AC3 decoders comparison here.
It would be very nice, if we can decode ac3 correctly only by eac3to, like "eac3to test.ac3 test.wavs -azid".
Thanks.

nickintheforest ... the azid.dll should still be available from many BeSweet related sources.

Sorry, no support for azid planned. The test you're linking to is 1.5 years old and the guy reponsible for the libav AC3 decoder has seen and commented on the test results those 1.5 years ago, too, so I would say a retest would be needed to make sure those results are still valid today. And if they are, a bug report should be created for libav/ffmpeg, so that the problem is fixed.

Code:
For best AC3, E-AC3 and AAC decoding you need:
(1) Nero 7 (Nero 8 won't work!)
(2) Nero HD DVD / Blu-Ray plugin
Is that still accurate or is libavcodec on par now?

Code:
-phaseShift        shift phase (when doing stereo downmixing, see "down2")
-mixlfe            mix LFE in (when doing stereo downmixing, see "down2")
Should say downStereo instead of down2.

Not downStereo, but rather downDpl. Back channel phase shift is a typical feature of Dolby ProLogic downmixing; basic stereo downmixing would not care much about the back channels.

Curious, why the change from Nero to libav as the preferred DD decoder?

This is a significant update. I'll have to redo audio for all my recent encodes. Thank you madshi!

Hey there madshi,
This still doesn't appear to work with 5.0 DTS files.

@madshi:
Code:
Options:
-downDpl           downmix multi channel audio to Dolby Pro Logic II
-downStereo        downmix multi channel audio to simple Stereo
-phaseShift        shift phase (when doing stereo downmixing, see "down2")
-mixlfe            mix LFE in (when doing stereo downmixing, see "down2")
Since "down2" is deprecated, you might want to remove the references (see "down2") to avoid a newbie's confusion...
Anyway, thanks a lot for this invaluable tool!

We can't support downloaded (and fake) files.

But is't true eac3to 3.25 don't downmix 5.0 files (tested DTS, AC3 and WAV).

madshi, thanks a lot for numerous fixes and improvements.

I asked that before and I don't want to annoy anyone, but I wanted to ask you, as a dev, personally - is there any chances for these ipms in a future versions?
• avi, mp4, mov, mpg, flv demuxing(maybe even muxing, that would be fantastic). Basically, avi/mp4 support is most important feature I think eac3to is lacking, along with
• Proper ac3 decoding. Whilst a freeware prog like azid can properly decode ac3, it's a real shame such powerful instrument as eac3to uses nero/libav for that, because both decoders has defects.
• and also, downmix to mono and ac3/dts dialnorm applying - minor, but still useful features.

/Thank you.
