Download Article
This wikiHow guide teaches you how to remove unwanted audio in Audacity . There are a few different types of audio that you can remove, including sections of tracks, background noise, and vocals. Keep in mind that Audacity's vocal removal tool is rudimentary and cannot remove all vocals.
Things You Should Know
- To quickly remove background noise in any track, use the Noise Reduction tool in the Effects menu.
- If you want to remove an entire noisy section from a track, highlight the section with your mouse and press the Delete key.
- To remove vocals from a music track, use the Vocal Remover effect.
Steps
-
Select a background noise section of the track. Click and drag your mouse across a section of the track that contains only background noise if possible.
- If there isn't enough free track to do this, select the section with the most noticeable background noise.
-
Click Effect . This tab is at the top of the Audacity window (Windows) or the top of the screen (Mac). Doing so prompts a drop-down menu.Advertisement
-
Click Noise Reduction… . It's near the middle of the Effect drop-down menu.
-
Click Get Noise Profile . This button is at the top of the window. This will help Audacity determine what is background noise and what isn't.
-
Select the section of the track that you want to clean up. You can also click the track and then press either Ctrl + A (Windows) or ⌘ Command + A (Mac) to select the whole track, which is ideal if you're working with a song.
-
Click Effect , then click Repeat Noise Reduction . It's at the top of the drop-down menu. This will apply the suggested noise reduction to the track.
-
Reduce the noise again if necessary. Repeat the noise removal process if there's still a noticeable amount of background noise. You may have to do this several times.
- You can raise the amount of background noise removed by clicking Noise Reduction... in the drop-down menu and then sliding the "Noise reduction" slider to the right.

- You can perform this step multiple times to increase the percentage of vocals removed, though doing so may harm the recording's fidelity.

QuestionHow do I remove a section without moving the rest of the track? I'm trying to cut out an intro but I want everything after it to remain in the same place.Community AnswerInstead of trying to delete the section, I would use the "Generate... Silence" feature and overwrite that part of the song with silence. That will prevent the shifting.

QuestionHow do I delete laughter off of a song?Community AnswerLaughter would be tricky. Your best bet is probably to use "Effect... Noise Reduction." You can then choose the best example of the sample noise possible (the laughter, with as little music in it as possible) and Audacity will do its best to filter the sound out.

QuestionHow much time should I add between songs that I copied from a cassette tape to split them?Community AnswerYou only need to add a few seconds, but if you want to be specific you could look up the songs and match up to the official song duration.
