I'm editing audio for a feature film and there is a significant amount of electronic noise on the audio tracks. We used a zoom recorder which I think is responsible for it. I tried to get the producer to invest in an amp to boost the boom mic before going into the zoom, but he opted not to get it.
There are also a few tracks where there are some various outside a/c units in the background and things like that which just sound like white noise on the track.
I've used bias soundsoap2 (never used pro) in the past, but the results are often weird and unnatural sounding.
What's the best tool for removing this type of noise under $1,000? Soundsoap pro 2? Or is there a better one you would recommend?
