Basically you select a portion of your WAV file which is all noise and nothing else, drag it out of the sound file, and then select "Effect > Noise Removal" and click "Get Profile". Once you've performed this step, telling Audacity what the offending noise "sounds like", select the portion of the audio from which you want the noise removed, click on "Effect > Noise Removal" again, and select "Remove Noise". This may take awhile depending on the length of audio selection from which you are removing noise. If you only have a small amount of Noise Removal to do, then try to select only those areas with the worst noise, as noise removal is an approximation and can expose sound artifacts and may take away some of the music. However, as Noise Removal does cause obvious changes in quality, if a greater level of Noise Removal is needed, you may want to apply the noise filter to the entire track, to make the entire WAV file sound consistent.
