Noise Reduction in Audition CS5.5

Noise reduction is almost a must in any audio recording, unless you’ve got a fancy studio and great microphones. Luckily, removing noise isn’t that hard in Audition. However, if you can’t isolate the noise on its own, there’s not much you can do to take it out, so make sure you can get the “noise” on its own so that you can extract it later.

First you’ll want to open up the file you want to edit. Once the track pops up, you’ll want to select the part where there is noise you want to extract. This can be done by clicking with the cursor and dragging. The highlighted part will be white.

After that you’ll go to Effects > Noise Reduction > Noise Reduction (process)

A window will appear, and your audio will begin to play. There is a button toward the top that says “Capture Noise Print”. Click it.

This lets Audition know what kind of noise you want to remove. You have to make sure the noise you selected is long enough, however. If you select a small amount of noise– –you won’t be able to remove it.

So you  have to make sure you’ve gotten a big enough section.

Once you’ve captured the noise print, click the button that says “Select Entire File”. Once you’ve done this, your clip will begin to play with the noise removed. Sometimes it’ll remove just enough and other times it will remove too much. In this case, you can click Cancel and try to find a more isolated bit of noise. If you’re satisfied, click “Apply” and you’ll find your audio that much cleaner! Good luck!
