How to Use Audacity for Better Audio Editing | Everyone knows, Audacity is the default software for multimedia content creators because it is not only free, but also relatively easy to use. As a bonus, it doesn’t consume much CPU power of your computer, so it can run on almost any computer.
You can use Audacity to record interviews, edit podcasts, and even create music. Audacity is a powerful tool for editing audio, whether you are recording directly into Audacity or downloading samples from elsewhere.
Audacity is a free audio recording and editing app with an easy-to-use interface. Knowing a few editing tips can make Audacity a lot easier to use for simple tasks like touching your footage or trimming silence.
So, here, I am going to review tips on how to use Audacity to use when you are editing audio for better results.
1. How to Trim Audio in Audacity
One of the first edits you usually need to make to an audio file is trimming the parts you don’t want to keep. This could include a silent sound at the beginning or end of the recording, or a part you don’t like in the middle.
All you need to do is click and drag across the audio options in Audacity. If you can’t select any audio, press F1 to make sure you use Selection Tool. Then press Ctrl + X (or Cmd + X on a Mac) to cut it. Alternatively, press the Delete key to delete the selected audio.
After you cut the audio, Audacity automatically closes the gap you created to remove the one you cut earlier. This is done by moving the next audio file to play immediately after the edit point.
2. How to Move Audio in Audacity
Audacity offers many different ways to move audio files, although none as intuitive as you’ll find in other free music production software.
The easiest way to move audio files in Audacity is to use Time Shift Tool. Press F5 to switch to this tool, then click and drag the audio file to move it left or right. You cannot make one audio clip overlap another using this tool; You can only move it to the edge of each file.
To make two audio files overlap each other, go to Tracks > Add New and move it to a separate track.
Or, follow the first instructions to trim the audio. Then use the Selection Tool to select a new position in the timeline and press Ctrl + V (or Cmd + V on a Mac) to paste the audio in a new position.
To move the entire audio clip, double-click it with the Selection Tool, then cut and paste it in a new location.
3. How to Get Rid of Silence in Audacity
When you are editing a voice recording, there are many parts of the silent sound that you need to remove. Instead of using the steps above to manually cut the silence from your audio recording, Audacity offers tools to automate the process instead.
I do not recommend this tool for music tracks, because it changes the timing of the show. Though it is very useful if you use Audacity to record interviews.
Use the Selection Tool to click and drag the audio section that contains all the parts of the silent sound that you want to remove. Double click on the clip to select the entire audio file.
Then go to Effect> Truncate Silence from the menu bar. Tweak the settings in the pop-up window to make sure Audacity only removes silence from your audio.
Use the bottom half of the window to choose how much silence remains after Audacity removes it: a certain period of time or a percentage of its original length.

4. How to Remove Background noise in Audacity
If you are recording in an open space, you may hear a lot of background noise in your audio file. Luckily, Audacity includes editing tools that you can use to make your audio recordings even better by filtering out background noise.
This tool works best for consistent sound sources, such as AC or white noise. But it is less effective at eliminating irregular sounds, such as traffic or conversation.
To get started, look for the audio section that contains only background noise. Then use the Selection Tool to highlight this part and go to Effect > Noise Reduction. In the pop-up window that appears, click Get Noise Profile.
Now you can try to get rid of it. To do so, select the rest of your audio track and go to Effect > Noise Reduction again. This time, use the bottom of the window to choose how much reduction you want to apply.
Be careful not to use Noise Reduction too much, as this can degrade your audio quality.
5. How to Amplify Audio in Audacity
Even though you have recorded the audio as loudly as possible, sometimes there are certain parts that are not audible. Audacity makes it quick and easy to change the volume of your files.
Select an audio file and open it Effect > Normalize to enlarge it as much as possible without causing distortion.
Or, press F5 to choose Envelope Tool, then click and drag vertically on the audio file to dynamically adjust its amplitude. You can also click on different points in the file to create new nodes, then drag those nodes to gradually change the volume of the audio file over time.
It is best to use this tool conservatively. If you need to make a lot of changes to get your audio to a consistent volume, use the Compress effect instead. It automatically increases the volume of the quietest part of the audio file without leaving the rest too loud.
6. How to Remove Audio From Video in Audacity
Copying audio from video files is quick and easy in Audacity. The only requirement is that you install the FFmpeg library, which allows Audacity to work with common video files. You can find the link to install this FFmpeg library from Audacity preferences.
On Windows, go to File > Preferences from the menu bar (on a Mac, go to Audacity> Preferences). In the Preferences window, select librarythen click Download next to FFmpeg library.
This opens a page on the Audacity Manual website with instructions for installing the FFmpeg Library for Windows and Mac. Follow the link required to install the plugin.
After installing FFmpeg Library, go to File> Open in Audacity and select the video file to import the audio. Your missing audio will appear in its own channel in Audacity.
7. How to Mix and Master Audio in Audacity
After you finish editing in Audacity, you have to mix all the tracks together to create a good balance between them. For mixing in Audacity, use the two sliders to the left of each song to adjust Volume and Pan.
In general, keep the bass-heavy instruments and leads towards the center, then adjust the volume slider so that you can hear each song clearly.
While mixing, you can also add effects to your tracks to make them even better. To do this, select the audio region, then open the menu Effect and select effect then select apply. The best effects to use when blending in Audacity include:
- Graphics EQ: change the pitch by adjusting the bass, treble, and mid-range frequencies
- Compressor: reduce dynamic range to make the quietest parts more audible
- Reverb: create the impression of space by adding room sound
Audacity doesn’t provide any output channels, so if you want to master your project, you need to export the mix first. After exporting, import your mixed audio file into a new Audacity project, then apply effects to the entire audio file.
When mastering, your goal is to make fine adjustments to the entire mix. If you need to change one track, go back to the mixing stage and export again. As a final mastering step, use the Audacity Limiter effect to make your project tougher without breaking it.
