Ruby library for DTMF detection

Ruby
1

Hi,
I am looking for a Ruby library for simple DTMF tone detection. It would
be
presented with an audio-file / continuous-stream and it should detect
DTMF
tones in it.
Is there one already available somewhere?

TIA

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.
