Surely you have ever used an electronic device to record conversations, sounds or even music. However, most of the time, the recordings made tend to be very noisy which decreases the actual quality of the recording. Noise can also be found in poor quality .mp3 songs.
If ambient noise detracts from the music or voice throughout the entire playback time, then it will be indicated to perform an elimination of ambient noise or at least a reduction of it. Podcasts, songs and voice recordings or any MP3 sound files that need a polished production, their background noise should be eliminated.
Obviously, to improve the quality of both your recording and a song, what we will have to do is eliminate background noise in order to hear the real content in a much clearer way. This can only be done using editing software.
There are currently a large number of sound building programs, however most of them are paid. However, there is a program called Audacity, which is open source and totally free. As if that weren’t enough, this software is quite powerful and offers a wide range of tools, such as removing background noise from songs or audio files in MP3 format.
That said, below we want to show you step by step how to eliminate background noise from audio files, whether they are recordings or songs, to improve the quality considerably:
How to erase the noise from any song or conversation in Mp3 format.
The first thing to do is download and install the free Audacity program.
Once installed, you must open the program and open within it, the audio file from which you want to delete the audio track.
Separate the stereo track by clicking on the name of the file displayed on the left side of the track and from the contextual menu select the option: Split Stereo Track.
When the track is divided, you will need to select a portion of the audio file where only the ambient sound is heard. We will do this by dragging the mouse cursor while left clicking on the ambient sound section.
Note: This audio selection will be used by the noise reduction function to find similar noises and eliminate them.
Once we have selected the section of ambient sound we will have to go to: Effects> Noise reduction …
This will open a window with a two-step tool. First, you will have to perform step 1 by clicking the button: Get noise profile.
Note: This profile has already been selected.
At this point, the noise reduction window will close. Don’t let this confuse you. Instead, select the audio part from which you want to remove ambient sound. If it’s the entire track, simply left-click on the track header to select the entire track.
Now you will have to go back to: Effects> Noise reduction …
In this case we will have to carry out the second of the steps. In most cases, the default Noise Reduction, Sensitivity, and Frequency Smoothing settings will do a good job. However, if you prefer, you can use a different configuration.
To continue, you will have to click on To accept. It may take a while for noise reduction to be applied, depending on the length of the track.
Once this is done, you can preview the results. If you are happy with them, go to File> Save to keep the changes or if you are sure of them, you can export it to an mp3 file.
