I heard a similar thing through my laptop speaker this summer. It was very clear. I heard a person typing away at their computer, chair with wheels moved, a person walked to a faucet, turned it on (running water) then off, returned to their chair. Typing ensued as well as papers being turned... heard breathing. I did not hear music or someone speaking. I disconnected the wireless internet, it was not hard connected, but still heard the person/sounds. It lasted about 5 minutes. It disturbed me so much I went out and bought a new wireless router.
Additionally, I hear a sound like a camera shutter every now and then. There are no advertisements running or any other reason for the sound. The camera shutter sound happened often during the summer. It was quiet for a while after I bought a new wireless router, but the camera shutter sound happened again today. On top of that, this christmas eve day my android phone made the same sound. The camera app was not turned on. I have only heard it that one time on my cell phone. I hope it isn't some type of malware!
btw... never have been on the site askmefast.... never even heard of it.
