I have gqrx app connected to RTL-SDR dongle. I am able to tune into and hear as audio specific RF frequencies, such as my car keys at 315 mHz. I use Keyboard Maestro to trigger lots of macros on my computer. How can I capture this audio on my Mac and link it to trigger a macro or keypress when car keys are clicked?
Using Fluther
