Help dealing with AAC audio plz

[InuyashaSama]

Since installing the AAC ds filter doesn't help VirtualDubMod to recognize the audio stream format from an MKV, I simply demuxed it and try to convert it with BeSweet, which fails miserably, reporting it's an "unknown wave format". VD shows it as an A_AAC/MPEG4/LC/SBR 6ch stream but it treats it as a Non-decodeable audio format.

Is there some decent software capable of converting this demuxed AAC file to a plain and simple stereo WAV? I don't ask for a decoder for making it work in VirtualDub because probably no one ever took the work of creating such thing.

I just don't get why people insist in using these highly-annoying formats such as AAC when there is no decent software to manage and convert it properly.

Have you tried the latest BeLight package, with NERO AAC .DLLs installed?

Have you demuxed the aac with virtualdubmod?
Demux it with mkvextract (shipped with mkvtoolnix).
You'll get an aac-file in *.aac and can convert it with besweet or belight or whatever.

Btw. aac isn't a highly-annoying format only because VirtualDubMOD can't handle it and only demuxes it as aac with a wave-header. You should probably use an other program, that it able to handle modern formats besides avi properly...

Afaik, BeSweet-BeLight can't decode aac files (only encode).

To decode aac you can use faad2 ( http://www.rarewares.org/aac.html ), BeHappy (with DirectShowSource), ffdshow, foobar, ...

Oh, i never tried it.
I always use foobar for transcoding.
BeLight only for encode multichannel ac3 or wav to aac.

This may or may not help you (I haven't tested with multichannel, but it should work fine). Read the post in full, because there are some parts you will need to ignore since they don't apply to you.

Well thanks everyone. I've done it this way:

-Extracted the AAC stream with mkvmerge.exe
-Decoded the AAC to WAV with faad.exe
-Encoded the WAV to MP3 with the AVI in VirtualDub
