I agree that it's cool to see those vids where the boat is 1/4 mile away and you can still hear the sound, but it's really just novelty for the reasons Phil mentioned. Just think of all the times the audio gets compressed and swapped between devices before it finally makes it to your ears. Even if you assume the tower speakers are perfectly reproducing the original audio you still have to make the very ugly jumps to the camera mic > camera hdd > compressed to youtube > uncompressed to computer speakers. :)
