How to extract ND HE-AAC from .mkv & convert to 6 mono wav ?

mkvextract -> faad2 -> wavewizard

For what do you need the 6 mono wavs?

Dear tebasuna51 , some client thought this would be his fastest way of sending his AD across the world for advertising. Thats all I have to say.

Im using faad -b 24 "D:\QuickTime_1080p_Trailers\up-tlr2_h1080p_track2.aac" > output123.wav but it does not work , my source is aac 5.1ch.

You need read the command syntax (faad without parameters) before construct the command line:
-o X Set output filename.
...
-b X Set output sample format. Valid values for X are:
1: 16 bit PCM data (default).
2: 24 bit PCM data.
3: 32 bit PCM data.
4: 32 bit floating point data.
5: 64 bit floating point data.
and now use:
faad -b 2 -o output123.wav "D:\QuickTime_1080p_Trailers\up-tlr2_h1080p_track2.aac"

Or you can demux the AAC from MKV, then decode it to wave with Nero AAC Decoder 1.3.0.0, then run it through Wavewizard to split it into mono waves - reencode to AC3
