AAC-HE and Matroska: is it possible?

i want to know if muxing an AAC-HE file created with besweet 1.5b22 (bsn rulez) and nero's dll version 6.0.0.11 into mkv is possible. i make some test but if i try to mux aac-he file into matroska, the central channel of my 5.1 file goes to the others channel :mad: . if i mux an aac-lc it's all ok. someone could help me? i used mkvtoolnix 0.7.2, matroskaplayback pack 0.6, matrixmixer 0.30b sorry for bad english, but this is my best :p

Welcome to the forums. Please post your commandline used. If you had read the mkvmerge documentation, you'd find that when muxing a HE AAC you need to use the switch --aac-is-sbr, which tells mkvmerge that the AAC is HE. I don't know if this is causing your center channel problem, but since you said LC works fine, it's worth a shot. By the way, why are you using matrix mixer if your AAC is 5.1 ?

Make sure you are using 6chold switch.Or in Oagmachine select 5.1(old).

thanks for your reply. I forgot this particular :rolleyes: , i always used the "--aac-is-sbr 0" command when i trying to mux an aac-he file. i use matrix mixer because someone say me if i want to hear aac file i must install the matrix mixer (and coreaac decoder too). I must disinstall it(the matrix mixer)?

this is the command for creating aac file: BeSweet -core( -input C:\AIita.ac3 -output C:\aacAI.mp4 -logfilea "d:\BeSweet.log" ) -azid( --maximize -c normal ) -azid( -oc,l,r,sl,sr,lfe ) -bsn( -6chold ) and this is the command for muxing it into matroska \mkvtoolnix-0.7.2>mkvmerge.exe -o "d:\AI\provazza.mkv" "d:\AI\4.avi" "c:\aacAI.aac" --sync 0:-88 --aac-is-sbr 0

welcome to doom9, DamnedSoul try to mux directly from the .mp4 (without the aac-is-sbr switch) in mkvmerge - it isnt necessary anymore to demux to .aac first...

And also the channel re-ordering switch in the -azid() section of the BeSweet command line isn't necessary anymore. Just use -bsn( -6chold ) for Nero <= 6.0.0.11 and -bsn( -6chnew ) for Nero >= 6.0.0.15. The rest is done by BeSweet automatically. tiki4

i have tried what you have suggested and this is the result: (coreaac decoder properties) AAC+SBR 24000 -> 48000 hz 6 -> 6 thanks a lot for your help, now i will use ONLY matroska (and aac too) for my rip :p

i want to know how to playback this type of mkv(he-aac+xvid) sorry,i'm a newbie,and my english poor

You need the Matroska Splitter filter from . And also the Core AAC DirectShow filter from the end of this in the HydrogenAudio forums. Unpack the filter somewhere on your system and register each of them with the following command line: regsvr32 MatroskaSplitter.ax regsvr32 CoreAAC.ax Enjoy! tiki4
