On the other hand, Associated Press has put online what they claimed to be the first public audio of the sound allegedly broadcast to the affected persons in Cuba:

I AGREE

Obviously, major news medias then analyzed this audio file, like in making a specter analysis. And cautiously commented about it, a worthy example being an NBC article: "Listen to What Americans Heard in Mysterious Cuba Sound ‘Incidents’".

Well, I've made with Audacity a sound specter of the AP file:

Out of the obvious 50-240 Hz AC hum/noise background parasitizing the recording device (I've a lot of it on my own records ), what's curious is around the 7000 Hz peak. I'll focus on it if you're interested.
Forgive me, but I have an immensely difficult time believing this is inadvertent leaking sound from radio equipment, or some badly-installed air conditioning unit.
