How to Change Pitch in Audacity[Tutorial]

By Lois Green, Friday, May 29, 2020

Sometimes when you have a favorite song and want to sing it but find that it is outside of your vocal voice, to make it match or harmonize with the key of your voice, you may need to adjust the pitch of the song. Or, when you are making a funny video and want to change the tone of the voice, a pitch changer would be helpful.  

In this post, we will introduce a professional audio editor to you: Audacity

In addition to changing the pitch of an audio, you will also learn how to change the pitch of a video file.  

Change Pitch of Audio with Audacity

Audacity is a pitch changer that has so many features. It not only changes the tone of a song but also speed, tempo, and trimming the audio. Let's see how to do it.  

Step 1 Download Audacity. 

Audacity is useful in trimming audio and has so many sound effects, and it is free to download and use. Go to the official website to download it. When you finish installing the program, move on to the next step.

Step 2 Import the audio file. 

Drag the audio file into it directly or click File > Import > Audio. You will see that the audio file shows in the track as a waveform.

Step 3 Change the pitch. 

If you want to change the pitch of an entire song, hold on the Ctrl+A to select the whole song. If you only want to change the pitch of part of the song, click on and drag the slider to highlight a certain part.

Note: 

Some audio files may have two or more waveform when you drag in the audio track, that's because it is in stereo. You can select both of them. 

Once selected, go to the top menu bar and select Effect > Change Pitch. In the prompt, you can change the pitch by note and set the semitone as well.
