If you couldn't find anything, try looking for any library that does
it (i.e. it will most probably be written in C/C++) and then look for
ruby bindings. Try looking around Asterisk (Open source PBX software),
they might have such functionality - have look at what they use.
If you could find a command line version, then audio file recognition
would be possible using `` or Kernel#system.
