identify this noise, please?!
About 14 minutes into a 17 minute clip, I started getting noise that sounds like the pops and crackles of an old, scratched LP record. I had a shotgun mike on a boom, so nothing was rubbing against the mike.
This is the noise:

Other equipment used:

Macbook Pro w/ Bootcamp & Win XP
DV Rack HDFor most of the clip, the sound was fine. Any thoughts? Thanks.

Hi Philip-
It “sounds” like there are two things causing that noise: one is something rubbing against the windscreen (though, you said nothing was). The second sounds like ether a bad/loose connection or a problem with the cable (or just a bad cable). Whatever it is, I believe it’s with the cable or mic/cable/connection.
I’m not sure you can filter it out but I’m not an expert in post-sound production so, maybe someone else here can help with that.

The XLR cable I used is several years old, and not always treated gently. I guess that’s a prime suspect.

I would trouble shoot it. Take the cable you were using and check it out with the camera you were using. Wiggle the connectors while listing with headphones and see if you can recreate it. Last year I bought two brand new 50′ XLR cables and they were both bad. The manufacture replaced them free of charge. Even new cables can have problems.

Whatever caused it, you might be able to clean it with iZotope RX using a combination of the declicker and spectral repair tools.
