Cleaning Up Audio in Adobe Audition

November 9, 2019

Can you here that? No? Allow me to bump the levels. How about now? You see, you might not realize it, but
most microphones like the one we have mounted above me, will pick up some
audible hum from the room they’re in. Whether it’s mechanical sounds,
air conditioning, or forced air. Microphones are really picking
up noises of all kind. Today, we’re gonna talk about how to
remove those noises after the fact, and get your audio right, every time. Before we begin, it’s important to note
that this technique works best when done before you’ve made any cuts or
alterations to your footage. This way, you can apply the effect
to the entire audio clip, instead of having it for
each individual cut. With our footage and audio loaded and
synced into Adobe Premier Pro, we’ll right click on the audio track and
select Edit in Adobe Audition. We’ll then wait for
the program to open Immediately our audio file will pop up in the editor,
and we can begin the clean-up process. The first step is to
capture the noise print. This is basically a short sample of the
noise you wish to remove from the clip. In our case,
a great sample is at the very beginning. We’ll use the Zoom In tool to zoom in on
the beginning where our cursor is, and select our desired part. Once you’ve selected a part where
your speaker isn’t talking, play it through just to make
sure no other sounds occur. Once we have selected our desired noise,
we’ll go up to the Effects tab under Noise Reduction Restoration,
and then click Capture Noise Print. A dialog box will open,
saying that the program has captured and analyzed the noise print. Click OK. We’ll then go back to Effects,
under Noise Reduction Restoration and click Noise Reduction Process. We’ll make sure our noise reduction
is around 80% for our first try and hit Apply. You can now see that some of the wave
forms when the speaker isn’t talking have been deleted. You can now listen through your
footage to see what it sounds like. If the clip sounds too tinny,
you can always hit undo and go back and
reduce the amount of noise reduction. Less noise reduction usually results
in a more natural sounding piece. However, more background
noise will be present. Once we have a result that we’re
happy with, we’ll hit File, and Save. Now the file’s been
updated in Premier Pro. You can now close Adobe Audition. Back in Premiere, you can see that
the audio file flashed and refreshed. This means that the audio
has been updated. We can now add an EQ effect to our updated
audio to add a more natural sound. Under the Effects tab, we’ll type
in EQ and drag it onto our audio. We’ll then go up under
the Audio Effects and hit Edit. What I usually like to
do is boost the lows and the highs to add a more natural sound. This will add some of the bass back
from when we reduced the audio. Play around in the EQ to
get a result that you like. Once you’re happy with your result,
you can close the dialogue box. With that complete, you can begin the
editing process with high quality audio.

    It didn't do it throughout the audio, only the part I highlighted
