Waking Titan Videos - ECHO is the Key

…to cleaning up the videos. I was trying all types of filtering…trying to hear what was being said in the videos. Nothing was working. Then (light bulb) I heard the recent Japanese Missile Warning system being announced…and heard how the echo of the loudspeaker sounded much like the distortion on the videos. 国民保護サイレン Jアラート 北朝鮮 North Korea Missile japan Japanese Protective Siren 2017/8/29日 - YouTube

Now I am searching for a good audio/video editing solution to remove echoes from audio/video…so I can hear what is being said.
