Is there a way Sound Forge can eliminate say a squeaky door noise or other not wanted artifacts within a sound field of music or talking?
To accomplish something like this you would need to either edit the sound out by making a selection around the unwanted sound and muting or deleting it, or perhaps by copying and pasting sound from a different place in the file and then pasting that over the unwanted portion. The effects in Sound Forge that you might use to help with something like this are the EQ or Noise Gate which can sometimes filter out unwanted noises and frequencies. Otherwise there are other third party plug-ins, like this one from Izotope that may do what you need. Sound Forge does support any DirectX or VST based effects.
