I just completed a quick analysis of an ~8hr sound recording from the camera array. I looked for "blips" of sound that stood out above the virtual flat line of almost minimal noise, and then amplified them. I think the person making the stream just has a mic on in their apartment; you can occasionally hear pots and pans and chatter and music, along with muffled traffic noises. I did hear what sounded like a jet flying by early in the recording, and about 20 minutes ago, while I still had it on live, there was an air raid siren, but nothing to indicate anything happening. One online comment was "is it a stinkbug warning siren?", or something like that :) There were occasional little "puffs" of sound, that could have been distant explosions, but the audio being streamed is very low resolution, so anything below a certain db couldn't be significantly improved by amplifying. My conclusion is that there was no bombing in Kiev last night, so if any MSM reports there was, it is just another example of their lying.
