Unable to convert .aac file

Asked by LarryJ

I am trying to convert an audio file which has an extension of .aac (Mime type: audio/aac)
The ksoundconverter log file shows ...

Got file
Executing next step
Decoding
/usr/local/bin/faad (temp input,aac and output .wave files listed as expected)
Output: **** Ahead Software MPEG4 AAC Decoder V2.7 *****

/tmp/kde-lj/soundconverter61nvcc.accfile info:
RAW
Error: Bitstream value not allowed by specification

mplayer and amarok both play the file without a problem.

If I request a conversion to .mp3, an mp3 file with the same basename is created but it's only about 1K in length and doesn't play.

Any suggestions? What Bitstream value is not allowed by what specification? Larry

go to the backends tab in the preferences dialog and choose mplayer (or whatever is available and works) as decoder for aac files.

Thanks HessiJames, that solved my question.

Certainly beats my piping scheme...

For the benefit of others, in Settings, Configure SoundConverter, Environment, under programs I found "/usr/bin/mplayer". Then I clicked the "Backends" tab. Under aac, I clicked the
decoder drop down where I selected "mplayer".

Now conversion to "High" quality .ogg works fine. So far , I can't tell the difference between my input .aac and the "High" .ogg ( except for the 5X increase size which I don't care about)

Thank you!
