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.
