I didn't understand the reference to audio either. When I on the crew of a US ballistic missile submarine more than 40 years ago, our main communications receivers were AN/BRR-3 units whose full frequency range was only 14 to 30 kHz. These received signals from coastal stations operating at megawatt output levels, but there was no one near such a station with his ear drums damaged by or even sensitive to the station's continuous output. :-)
Anyone can listen to such signals as they exist today. I'm not sure what the point would be...everything down there is very deeply encrypted.
