HI

your question is confusing

try to use dbpoweramp to convert acc file to mp3 but got this error message

from aac i guess to mp3, and then ...

"The Codec Require to compress 'D:\inu\track2.mp3' could not be open"

from mp3 to aac.

which one are you doing?

[celtic_druid]

If it is aac-->mp3 then from the error message it is having trouble compressing to mp3, not decompressing the aac.

HI

"The Codec Require to compress 'D:\inu\track2.mp3' could not be open"

i think he's trying to compress some mp3 that he has on probably CD(D:\)
to aac so that he could listen to them on his new brand ipod.

its only the title of the post that confused me

he hasnt come back to say anything.

sorry to confuse you. I tried to convert from acc to mp3. that file is on my second hard drive. "The Codec Require to compress 'D:\inu\track2.mp3' could not be open" this is the error from dbpoweramp

I've tried several software without successful. Finally, here what I've it done.
1-Demux it using MKVExtract, command line batch file looks like this:

REM Change to dir of files need to demux
REM Path to command and path to file is MUST
REM Tag ID = 1 avi file, Tag ID = 2 aac file, Tag ID = 3 srt file
REM the paths for demuxed files are also showed
cd C:\2_author\Dae
C:\MKVExtractGUI\mkvextract tracks C:\2_author\Dae\Dae.Jang.Geum4.mkv 1ae.Jang.Geum4.avi 2ae.Jang.Geum4.acc 3ae.Jang.Geum4.srt

I don't use GUI b'cause it won't allow me to name my converted files

2-Convert aac file using aacDECdrop (it may ask you the file libmm.dll to run) you will have a wave file as large as mkv file.

3-I guess you can take it from here

It works for me

If you link against libmmds.lib instead of libmmd.lib when compiling then you shouldn't need the dll.

Just make sure that if the aac is he-aac that it converts ok without a header to let the decoder know that it is he-aac.

Easier to just do do mplayer -ao pcm:file=Dae.Jang.Geum4.wav -vo null -vc dummy Dae.Jang.Geum4.mkv

Decode to wav directly from the mkv, no need to demux first.

[mickdarson]

Yeath , Celtic is right. It's much easier, I tried but the wave file is as twice as big and mplayer writes wave file to its dir only, tell me please if there's another way.... Cheer

[celtic_druid]

If the wav is twice as big then it suggests that I was right previously, it was he-aac and it was decoded without the SBR part. No SBR = 1/2 sample rate = 1/2 size = crap quality.

As to how to output to a different directory. Bit tricky under windows as you need to do c:,etc. and ":" seperates options so you can't use it. Guess you would have to do it via mingw/cygwin so file=/c/audiofiles/whatever/something.wav

I thought that it extracted to the current directory?

[Cornucopia]

Doesn't it support quotes as a means to depict LFN paths, as most modern command line apps do?

You know,

RUN MPYAPP.EXE IN_FILE.IN "C:\Documents and Settings\Joe Blow\Out_File.out"

You could always cheat with SUBST, running the app with the app, in_file, and out_file as part of the current directory...

[celtic_druid]

Quotes should be fine but in your example you still have a ":" so I don't think it would work.

[Cornucopia]

No, that's the idea of quotes, anything within the quotes is part of the filename. Just like if you had a commandline app that had switches separated by spaces, you use the quotes and even if there is a space in the LFN, it won't get treated as a separate switch, which it would had you not used quotes.

Try it. I just did and as I already suspected, it doesn't work. It can't parse due to the \ after the :.
