Shooting audio on an airliner
If I need to show an interview on a jet aircraft how do I get clean audio? I have seen programs that have very clear sound but when I shoot with a shotgun or lav. I get so much noise that it is almost worthless. Any ideas?

The high end programming is probably using ‘Automated or Automatic’ dialogue replacement, or ADR as it’s commonly known. Also the quality of the original aircraft audio would depend on the aircraft i.e. a 747 as opposed to a Cessna 152. Certainly a super cardioid mic would be helpful for rejecting side audio but I’m only guessing now.

Once upon a time I did shoot in an Aluminum Mill with 2 Sony Directional Lavalier mics (ECM55’s I believe) one facing the subject’s voice and the other facing away (Down on their own audio channels. In editing I used a mixer to reverse the phase of the background audio to cancel it out. The result was a bit lacking in bass and oddly enough I had to mix back in some background sound so that it looked normal. An Airplane is going to be tougher because the frequency of the engines is in the voice range whereas in the Mill it was much lower.

I’d mic it ridculously close and get plenty of ‘room tone.’ With a little judicious noise reduction in post you should be able to get something usable. Definitely an outboard mixer would be key and a great hypercardioid mic.

I’d make the same suggestion – get a good stretch of uninterrupted room tone, then use that as a noise reduction sample in Soundtrack Pro. I’ve found that in nasty situations like that, knocking the noise reduction back to 50% or so and doing multiple passes can have better than expected results.

The plane has to be turned off. Add the plane fx in post.
