How to Use Audacity Step-by-Step
Audacity is a very straightforward audio software, so it’s easier to grasp the basics. Follow the steps below to learn how to use Audacity on Windows and how to use Audacity on Mac likewise.
How do you use Audacity step by step? Here’s how:
Step 1: Find & import the file you want to edit
Start by importing an audio file into Audacity. It supports common audio formats such as MP3, WAV, and AIFF. You need to install the optional FFmpeg library for a more extensive range of formats. Note that Audacity cannot import copy-protected music files.
To import an audio file, select File > Import > Audio.
For a quicker method, just drag and drop the files into the Audacity window.
Step 2: Check the waveform
Stereo waveforms in Audacity look like the image above. The audio is louder where the waves reach or closer to the top or bottom (vice versa.) The ruler indicates the length of the audio clip.
Check the waveforms to detect any DC offset, which refers to a waveform that is not centered on the horizontal line at 0.0 amplitude. Most of the time, it is caused by recording with a faulty audio interface.
Select the clip, click on Normalize to remove the DC offset.
Listen to the audio by clicking on the play ▶️ and stop ⏹️ , or you can use the Space button as a shortcut to play and pause.
Step 3: Select and change the range of audio you want
To change any part of your audio clip, first, select the part you want to change. You can cut, copy, paste, and duplicate, just like editing a selected text.
The image above shows Audacity’s toolbar. So, how to zoom in Audacity? You can use the magnifiers to zoom in and out or View > Zoom > Zoom In (or Ctrl + 1) and View > Zoom > Zoom Out (or Ctrl + 3).
Zooming in and out helps you make the most of the window space. Once you select a specific range of audio and click on play, you can listen to only the selected part.
How to split audio in Audacity?
- Click on the selection tool, and select the split point in the clip.
- Then select Edit and Clip Boundaries.
- Select Split.
- Or use the keyboard shortcuts Command + I on the Mac or Control + I on the PC to Split the audio.
If you make any mistakes, you can always click on Edit > Undo.
How to trim audio in Audacity?
Make sure to stop the audio by pressing Space if it’s still playing. Select the excerpt you want to delete. Click on Edit > Remove Special > Trim Audio. You can undo or redo if you make mistakes. After you delete the selected parts or trim the audio, the remaining excerpt might be away from the track’s beginning. Use Tracks > Align Tracks > Start to Zero to align it.
However, this is not necessary when exporting the file because Audacity ignores the white space while exporting.
Step 4: Make the last second fade out
How to use Audacity fade out?
- Click the Skip to End button to go to the end of the track.
- Zoom in to see the last one or two seconds just before the end.
- Click the waveform one second before the end.
- Select > Region > Cursor to Track End.
- Then, select Effect > Fade Out to make the audio smoothly fade out.
Step 5: Export the final version
Mind that when you select File > Save Project > Save Project, you are just saving the file as an Audacity project, and it can only be opened with Audacity. If you want to open your file in other applications such as Windows Media Player or Apple Music/iTunes, you need to export it.
Before you export the file, go to the Import/Export Preferences and see under When exporting tracks to an audio file, thenuncheck “Show Metadata Editor prior to export step.”
This Metadata Editor adds extra information about the voice or music into the file. You can always check it back if necessary.
To Export a WAV file;
- Select File > Export > Export Audio
- Change the file name
- Choose a location to save
- Select the “WAV (Microsoft) signed 16-bit PCM” from the bottom of the save dialog menu labeled “Format.”
- Click Save.
To Export an MP3 file;
- Choose “MP3 files” in the save dialog menu.
- Click the Options menu to set the bit rate and other options.
Step 6: Test your audio
Finally, you should test the audio file you saved. Open the exported file (not the Audacity project file or the AUP in short) in Windows Media Player or Apple Music/iTunes etc.
Don’t forget to save the changes in your Audacity project file if you want to make additional changes to the final version in the future.
