This emindsca will show you how to remove audio from an Audacity track. Sections of tracks, background noise, and lyrics are all examples of audio that you might want to remove. Remember that Audacity’s lyric removal tool is basic and cannot remove all vocals.
Method 1 Cutting Sections of Audio
1. Open Audacity. It’s an image of an orange sound wave in the middle of a blue set of headphones.
2. Click File. You’ll find it in either the top-left side of the Audacity window (Windows) or the top-left side of the screen (Mac).
3. Click Open…. This is in the File drop-down menu. A new window will open.
4. Select an audio track. Click on a track that you want to edit.
5. Click Open. It’s in the bottom-right corner of the window. The track will open in Audacity.
6. Select a section. Find a section that you want to remove, then click and drag your mouse across it to highlight it.
7. Press Delete. This will immediately remove the section from Audacity.
You can also click Edit and then click Delete in the drop-down menu.
Method 2 Removing Background Noise
1. Choose a section of the track with background noise. If possible, click and drag your mouse across a section of the track that contains only background noise.
If there isn’t enough free track, just pick the section with the most noticeable background noise.
2. The Click Effect. This tab is located at the top of the Audacity window (Windows) or the screen (Mac). This brings up a drop-down menu.
3. Click Noise Reduction…. It’s near the middle of the Effect drop-down menu.
4. Click the Get Noise Profile button. This button can be found at the top of the window. This will assist Audacity in determining what is and isn’t background noise.
5. Select the section of 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.
6. 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.
7. If necessary, turn down the volume again. If there is still significant background noise, repeat the noise removal process. You may have to repeat this process several times.
By selecting Noise Reduction… from the drop-down menu and dragging the “Noise reduction” slider to the right, you can increase the amount of background noise removed.
Method 3 Removing Vocals
1. Select the whole track. Click the audio track, then press either Ctrl+A (Windows) or ⌘ Command+A (Mac).
2. Click Effect. It’s a tab at the top of the window (Windows) or screen (Mac).
3. Scroll all the way to the bottom and select Vocal Remover…. To find this option, you may need to click a downward-facing arrow at the bottom of the drop-down menu. When you click on it, a pop-up menu appears.
4. Select a vocal remover plugin from the drop-down menu. Click a link in the pop-out menu to the right of the drop-down menu. This will bring up the window for the vocal remover.
5. Click the OK button. Some of the vocals will be removed from the track as a result. While this isn’t perfect, you’ll notice a significant difference in the outcome.
You can repeat this step to increase the percentage of vocals removed, but doing so may reduce the fidelity of the recording.
