Hi!
Seems like I can create AAC+v2 encoding plugin with MP4 output using CT reference encoder (http://forum.dbpoweramp.com/showthread.php?t=7107).

Does anybody compared them with WinAmp one? Does You need this encoder?

does it do multichannel HE AAC? there's a free alternative to LC encoding with your faac plugin now, and 2ch HE with your winamp plugin but there's no multichannel HE solution yet.

Oh, definitely do I need this, and right now!!! :D

Seriously, I felt forced to revert to keeping the AC3 tracks for multichannel because of the artefacts of Nero's HE AAC. If my memory serves me right, Nero's first HE AAC releases were higher bitrate but less problem-ridden.

I defeneatly like this db HE-AAC v2 3GP. Comparing to winamp he-aac2 , I still prefer db one.

I guess it does: "aacPlus delivers streaming and downloadable 5.1 multichannel audio at 128 kbps"
from here (http://www.codingtechnologies.com/products/aacPlus.htm).

so the one they sell supports it.. what about the one we're talking about here? dimzon's code extract doesn't exactly inspire me with confidence.

I have been wondering this too.
But finally as a proof, check the id3v2 of winamp 5.1 he-aac(5.1 aac plus v2 by ct) bundle kaje_-_hey_buddy_aacPlus_surround.aac.(dbPowerAmp version idtag tool shows the full tags)
Winamp does not support multi channel encoding with this codec(I guess it is tuned mainly for cd 2ch ripping)

Maybe a precise checking of the interfaces of the open source and library is needed?
