For those of you who are wondering, there are a lot of cuts in this audio that presumably cut off the voices heard, and that this does not include the gunshot moments… but from what I can tell, from 0:00-1:12 the plane is stationary or taxing on the ground, then at 1:13 the plane is in its take off role, and by 1:53 onward, the aircraft is airborne Also at the very last second, you can hear a sneeze before the audio cuts off, it’s hard to hear, but distinctive once noticed
Is there any chance to clean this CVR? I think the only thing I could hear are the gunshots. Where did you find this CVR? It's an amazing discovery, even though the audio is almost unintelligeble
