How do I remove low battery interference from radio mic recording?
on Mar 4, 2014 at 12:32:25 am

Hi - I recently recorded a long series of clips with a client and wasn't able to closely monitor the audio - now that I'm editing I find that there is high-pitched interference on some of the clips, which I believe would have been from the radio mic batteries starting to get less than full (despite changing them often - grr)
Now I am trying to remove the noise in post - I have only recently switched to the Adobe suite and am wondering what the best tool would be?
The clips also have low-level hum from the light fans, which would also be nice to get rid of. The nature of the clips means I can't put some disguising music or sound fx on, so I really need to clean it up!
I've only recently made the switch to the Adobe suite, so have had a play with Audition without huge success.
Any help much appreciated!

Here's a good place to start:

If you can get a clean sample of the noise prints (Capture Noise Print), then you should have pretty good luck removing the noise. The low level hum should be a snap, since it shouldn't be mixed in at the same part of the audio spectrum as the voice. Possibly the same with the high pitched interference.
