No matter how cautiously you record an audio file, there is always some noise. At the same time as this noise may not be much of a problem for personal voice recordings, in case you consider sharing those files with a wider audience, it becomes a huge issue. Noise in an audio recording makes for an unkind listening experience. but, some amount of ambient noise is a great concept, because it makes the audio sound more natural, instead of making it sound produced.
In this article explains how to remove noise from your recordings. It’s very easy, and only takes a little bit of problems for larger recordings. It will be covering the procedure using two of the most famous audio editing apps:

Audacity is one of the most well-known applications for audio editing and recording. It is completely free and therefore, is the go to choose for most coming audio artists and for hobbyists who don’t want to spend a lot of money on registered audio software. Audacity occurs to have all the features that one possibly need for recording and editing their audio clips.
To remove noise from an audio clip using Audacity, we will have to follow these steps:
Note: It recommend making copies of your audio files before editing them on Audacity, just in case something goes wrong.
Launch Audacity and open the audio clip that you want to remove noise from.
Select a sample of pure noise from the audio clip. This is the part of the clip where you are not speaking, and only the background noise can be heard.

Next, go to Effect -> Noise Reduction and click on “Get Noise Profile“. This will grab the sample that you selected in the last step as a Noise Profile. In this dialog box, you can adjust the settings for the noise reduction, including the amount of reduction to be applied (in dBs), the sensitivity, and the frequency smoothing that you desire in the output audio.
Go to Effect -> Repeat Noise Reduction. You will see a dialog box expressive you that the noise reduction is in process, and once the dialog box closes, you will be able to hear a significant decrease in the noise levels in your audio.

Use Adobe Audition CC to Remove Noise
If we would relatively use an exclusive tool for our recording purposes, we can go with Adobe Audition. Audition is a simply great recording studio, and it comes with all the features and it is a clean interface. In this case my opinion select Audacity, but if you need Audition, fret not, the method is quite much the same.
Launch Adobe Audition, and load the recording that you want to remove noise from. Once done, select a part of the audio waveform that is pure noise. Pure noise is the part of the clip where you are not speaking, and only the background sound, is audible.
