How can I reduce hum or hiss in my audio?

How can I reduce hum or hiss in my audio?

Sometimes a location sound track has hiss (white noise) or a 60 Hz hum that is audible. If the sound is constant, there are some software packages and plugins that can reduce the problem somewhat without affecting the audio quality terribly. Some of them are:

Ray Gun
Sound Soap
Soundtrack Pro

If the background sound you want to remove is not constant, like wind noise, a dog barking, or music playing, then you will need to reshoot the scene or do ADR (automated dialog replacement). (You cannot "cut" a subject’s speech out of the background sounds like you can cut a subject out of their background in Photoshop!)
