Don't you need to apply a phase shift for matrixing?

I think is not necesary.

In dpl downmix the FC channel is mixed (and recovered) with FL-FR without phase shift.

The phase shift can be necesary in dpl if FL and SL (and FR with SR) are dependent and the mix between can produce problems.

BTW, you can test using:
sox -m -v 0.5858 SL.wav -v 0.4141 SC.wav new-SL.wav
sox -m -v -0.5858 SR.wav -v 0.4141 SC.wav new-SR.wav

If you have 3 surround channels and previously matrix the SC in SL and SR you can use Aften to encode and set the flag in header:
'Dolby Surround EX mode' to 'Dolby Surround EX encoded'

sox -m -v 0.5858 SL.wav -v 0.4141 SC.wav new-SL.wav

Ok, thx. However, i use AAC or dts es 6.1 discrete to reencode 7Ch Tracks.
But its the same Problem.. we have no (100%) proper Method to decode DD EX to 6.1/7ch waves ,also not for dts.
But this is the aften encoder thread ......

By the Way : Ive tested wave2ac3 2.1 x264 with rev786 SSE3Wow! The Perfomance is great. ~30% faster compared with DD Encoder Pro v7
The Quality is "fully" identical to the off. Dolby Digital Encoder Pro v7. Maybe i will switch to Aften instead of DD Enc Pro 7 from SonyVegas 8. Aften has no disadvantage

Did you try Aften on multi-core CPU? Aften is even faster with that kind of systems!

Tip:
To get even more performance set the:
"Fast bit allocation" to "Faster encoding"
and
"Fast exponent strategy decision" to "Faster encoding"

there is probably some quality impact with these settings.

Im encoding on a quadcore !6600 @ 3.2ghz..
No, i dont use FastBitAllocation/FastEx.Startegiy.D.....Its fast enough.

Is there a changelog regarding the various Aften SVN builds after v0.0.8?

http://aften.svn.sourceforge.net/vie...ften/Changelog

for changes after 0.08 please check point "version SVN : current"

i don't think there is changelog for each SVN build, you may try checking same revision of Changelog

What does the new mode of operation mean. And specific what does Transcoding do?

What exactly are you referring to?

Transcoding would be AC3-to-AC3, with essentially a decode/re-encode. Aften is setup to be able to handle this in the future, but does not currently do so. The main obstacle is that the decoder that would be used is currently under GPL. If/when it is ever relicensed to LGPL then it will be ported over to Aften from FFmpeg.

I have been working on Avisynth scripts support in WAV to AC3 Encoder, finally I have added some preliminary support for .avs scripts. Please find attached the version 3.0 BETA 1 of WAV to AC3 Encoder, it really needs a lot of testing before final release.

Changes in v3.0 BETA 1:
- Added preliminary Avisynth (*.avs files) scripting support (not supported in 'Multiple mono input' and in 'One per file' mode).
- Added *.avs filter to open dialog.
- Double-click on *.avs script in files list to show AVS File Properties window.

DOWNLOAD: WAV to AC3 Encoder 3.0 BETA 1
