Howdy folks, I have a quick question. I'm a Volunteer Firefighter with a bit of a sleeping problem. Our station gets dispatched on a certain frequency by the use of two tones (510.5hz for 2 seconds, then 2271.7 for 2 seconds) to set off the voice pagers/klaxons/strobes/big 'ol siren. I have my scanner connected to my computer via the microphone-in port (I'm running Ubuntu). What's the easiest way to grab information from the microphone, and determine/analyze the sound in such a way I can tell if my fire company is being dispatched?
The whole reason I'm doing this, is that we now use tiny fancy schmancy digital pagers, which can barely get my attention during the day, much lest bring me back from the dead at night. My room is already partially wired to a few relays/etc/etc, so I'd like to strobe the lights a bit, maybe make some noise. Please help this Audio newbie do some simple decoding.
