I'm asking this in the audio thread, as it's primarily an audio question, and I hope to enlist the aid of the audio experts on the forum. I am working on a movie project, and much of my production audio was recorded poorly. Some had excessive background noise, like a large industrial freezer humming to no end, some had wind or other interference, and some was simply recorded at too low of a level, creating hiss. What's the best application to use for filtering/EQ'ing out some of this unwanted noise? Are FCPs onboard filters & EQ settings sufficient, or does Soundtrack Pro or Garage Band have better tools? Or, do I go with a third party program, and if so, which one provides the most flexibility at a reasonable price? Thanks!
