swf-audio file to mp3

[dexus]

I am trying to convert a swf-audio file to mp3.
Here is an example of what the swf files look like:
http://download.omroep.nl/vpro/luisterpaal/albums/38371129/data01.swf

I have erightsoft's super, this program was able to do it using ffmpeg.
I have tried it using ffmpeg, but the program crashes:

ffmpeg -i data01.swf -y data01.mp3

Input #0, swf, from 'data01.swf':
  Duration: 00:03:36.8, bitrate: 63 kb/s
    Stream #0.0: Audio: mp3, 44100 Hz, mono, 64 kb/s
Output #0, mp3, to 'data01.mp3':
    Stream #0.0: Audio: libmp3lame, 44100 Hz, mono, 64 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
#And after that line the program just crashes

Could anybody help me with this? Should I add or change some command line parameters?

You could always use any of the available swf decompilers. Chances are, the audio is already in mp3 format (since the swf is just a container). You would simply load up the swf into the decompiler and export the sound file.

The audio is indeed already mp3

Input #0, swf, from 'data01.swf': 
  Duration: 00:03:36.8, bitrate: 63 kb/s 
    Stream #0.0: Audio: mp3, 44100 Hz, mono, 64 kb/s

But I don't have a proper batch decompiler that I can operate using the command line.
And I know ffmpeg can do it, super does it using ffmpeg. I can't see why it isn't working when I try it myself.

Report about "data01.swf":

--- Goldwave does not play it back properly;

--- Avi-Mux GUI extracted an unplayable .mp3;

--- MPC played it without a problem. I had to use Total Recorder for
transforming the audio track of the .swf file into a standalone .wav.

I have already met other "problematic" mp3 files, which had been encoded
so "weirdly" that only WinAmp could play them correctly, and only lame.exe
could convert them to non-silence .WAVs

Download SWF Extractor from...

http://www.19.5degs.com/swfextractor.php

It will decompile simple SWF files.

BTW, the extracted mp3 file plays fine.

SWF Extractor works indeed.
Only theres no way to use it with a command line command.
And I have to do more than 300 files, and theres no bulk-extract-option

Converting with lame.exe assumes its raw input and only outputs noise
Converting with mp3sEncoder.exe outputs something that sounds like music only much faster

I have been trying alot of programs, and then I downloaded:
MediaCoder Audio Edition

And somehow, the ffmpeg.exe thats installed with that program doesn't crash!
So I found a working version of ffmpeg and solved my problems.

Thanks everyone for helping me find a solution.
