I presume you want to play it out the speaker? I'm not sure if there's a 
portable way to do that, but in most unices it would be a matter of 
sending the audio data for that frequency to a special file, e.g. 
/dev/dsp. Or perhaps you want to save to a file. In either case, esp. 
the latter, ruby/audio would be worth a look.
