How to remove Microphone Background Noise on the fly Adobe Audition

For months I was looking for good noise reduction and finally I found it.

Before doing anything, make sure few things first.
To reduce noise, PC have to be grounded.
Microphone need good cable and connection to the sound card.
Sound cards are allot better than on board audio so if you can, use them.

You will need:
Adobe Audition
Virtual audio cable
OBS for recording.

(Don’t use pirated versions but I cannot stop you from doing so, so it’s up to you)
OBS you can download it here : https://obsproject.com/
Open Broadcaster Software is free and open source software for video recording and live streaming.


Now lets get started.

Short video explaining quickly what to do, if you need more in depth guide, continue reading.

Virtual Audio Cable will make link between Adobe Audition and OBS. This will enable you to record modified audio from your microphone (reduced noise, added effects etc.).

First open Adobe Audition and click File/New/Multitrack Session like this:

Now click R (Arm For Record) and I (Monitor Input) on your track like this:

Now click on Input/Audio Hardware like this:

In Audio Hardware choose your microphone like this:

Output leave default speakers so you can hear the noise and adjust sound levels, effects etc. Later you will change output to Virtual Audio Cable and create link to OBS for your recording.

Latency you can change for your liking, nothing special about it.

Under "R" (Arm For Record) there is small button Sum to Mono (this is in case if you have Stereo Microphone in but using only one channel like I do) click this if you can hear your voice on only one speaker/headphones.

Now click in Effects Rack, Noise Reduction/Adaptive Noise Reduction like this:

In Adaptive Noise Reduction adjust options for your liking and choose High Quality Mode but this will impact your CPU so I do not recommend if you have slow CPU and doing some resource hungry tasks like video capturing.

Adobe Audition is basically done, you can add some other effects to your microphone if you wish.
Now lets connect it to OBS and record something.

Click on Input and choose Audio Hardware like this:

Change Default output to Virtual Audio Cable and click OK.

In OBS open Settings/Audio and in Microphone menu choose Virtual Audio Cable like this:

Now click Microphone Noise Gate, adjust Thresholds to further eliminate remaining Noise and you are done!

If you have questions or suggestions please comment I will be happy to answer.
