Comment (by krisha):

 Sorry, I just used VLC and Audacity. Output on the VLC console:

 {{{
 [amr @ 03ff7a60] Estimating duration from bitrate, this may be inaccurate
 [amrnb @ 050b3ea0] Corrupt bitstream
 }}}

 If someone wants to fix it, I can compile ffmpeg and run the command. For
 me it's effort of some hours todo - for a developer wanting to fix it, it
 is just a minute (he has probably latest git head and complete environment
 set up already).

 But to understand the bug these two lines of VLC output should be enough.
 Anyway more important is the waveform after, than the output.

 The "Corrupt bitstream" output I think is also not right. Because Mode 15
 is NO_DATA and not an invalid mode.
