  • Select the entire audio, again open the Noise Reduction Window ( Effect > Noise Reduction ), set the values based on your requirement. ( you can leave the default values also as such),Click preview to check the audio and Click OK.    
  • That’s it. All the Background unwanted noise is removed from your recording.

If the noise still exists try applying the filter again. Make sure you do not overdo the process many times so that your audio will not be degraded and make your voice sound tinny and robotic.

 
Step 3: COMPRESS
 
Now that the audio is free from unwanted noise, it is time to compress it so that the volume of your vocals increases  (makes louder parts a little quiet and quiet parts a little louder). To compress your audio 
 
  • Select the complete audio track using Cltr+A, now click Effect > Compressor.
 
Compressor
 
  • Next, set the values as shown in the figure below

  • Once you set the values, click on Preview to check the audio, and once you are happy click OK.
You may need to mess with the compressor’s settings, just remember that the more you raise the threshold to the left, the more background noise you will hear. Keep the threshold between -15 and -18.
 
  • Once you apply the compressor, the audio will look like below.
