Aloha, Stan Trevis here
I've just opened a parcel where there were
these marble and wood watches
which I'm going to make a video and an Instagram post
so let's follow me there too
today I'll show you two different ways
to clean up the audio of your videos
the first one is for free but very basic
and the other one with the Adobe Suite thus
monthly subscription programs but with better results
A little clarification: in this video I'll only talk you about
the post-production, obviously for greater audio results
we have to pay attention to things such as the hardware
for example, I use a Rode mic (link in description)
or the location: choose a quiet place with low echo
Statistics report that every second
hours of video are uploaded on the internet
obviously of different "qualities"
but remember: when it comes to video quality
it is important to consider not only
the shot quality, the image quality
but also the audio track
the parts of speech, the voice itself
In this video I'll show you how to move from
this type of audio
to this one
Let's see the first way to improve the video audio track
by downloading Audacity straight from its official site
(link in description)
Once the download has been installed
it will be possible to drag the audio track in the program
we immediately notice that there is
a kind of noise in the silence areas
to remove it, we will have to select a moment of silence
click on effect, noise reduction
and then get noise profile
Now, select the all track
with cmd+A or ctrl+A
depending on the computer you are working with
let's move back to effect, noise reduction
and set up -20 decibels as reduction value
In this way the background noise has disappeared
But be careful because these variations
could affect the spoken parts too
To improve the voice it is necessary to equalize it
selecting all the track again
Move back to effect and open the equalization
Generally, I use two presets
"Bass Boost" to raise the low tones
and "Tremble Boost" to raise the high ones
which helps to better understand the voice track
After having normalized everything
to -1 decibel, the track is ready
So here we have the original track
and the final one
Finally, save your work by clicking on file
export and selecting the format you want
Obviously, there are other tools we can use
to improve the voice that, perhaps
some of you already know
however, I have never explored Audacity in great detail
Because I've always relied on Audition for specific edits
So let's see the other way to improve the voice track
jumping on the Adobe Suite
which I adore because in the editing stage
the programs work together
In this case I'm editing the video clip with Premiere Pro
where I'll just do right-click on the file I want to edit
and choose "edit in Audition"
Once we are in the program with the audio track
the first thing to do is to equalize everything
by using two tools
the first one to modify the mid/high tones
and the other one to adjust the base of the voice
Let's start with the first one
a piece of advice: pause the video and copy my data
but remember that the entries are not always the same
for this reason, it's up to you
to choose the best values for your voice
Let's move now to the Parametric Equalizer
where I'll use an Audition preset
I suggest you to find the best values
according to your voices
personally, I tend to set the low tones to zero
Then, note that the audio track has fluctuations
in the volume levels
and a thing that always annoys me
while I'm watching a video is continuously
turning up and down the volume
To solve this problem, use the Single-Band Compressor
by selecting a preset already there in the program
The audio track will result very low at this point
so let's normalize everything with a value
that enables you to not have such a high track
Remember that the speech part in videos
should swing between -15 and -12 decibels
(I'll also work on it later by using Premiere)
After that, select a silence area
click on effects, noise reduction and capture noise print
Now, move back to the audio track
and process the noise reduction
Once again, feel free to copy my settings
but, later, find the best values for your track
Finally, we can work on the most evident noises
by removing them manually
Now save the work and go back to Premiere
where the audio track has changed
So here we have the original track
And the final one
Hope this video was helpful
my friends are waiting for me at the beach
so see you in the next video
big hug from your friendly neighborhood Stan
