cannot install audacity with error about pdns (powerdns)

For some reason, the script to install audacity in debian has to be able to stop pdns successfully... (I know this is weird).  So, what you need to do is to start it first by:

# /etc/init.d/pdns_recursor start
# apt-get install audacity

converting .mp4 to mp3

$ mplayer -ao pcm in.mp4 -ao pcm:file="out.wav"
$ lame out.wav
