Merge MP3 VS Audacity – Which to Choose for Combining Two Audio Files

How to Combine Tracks in Audacity

You’ll need to figure out its interface and find the necessary functions. Let’s examine a case where you need to sequentially merge two files, create a smooth transition between them, and level out the audio, then save it as one file.

1. Place the tracks on two separate tracks so they overlap in time. The overlap is necessary for a smooth transition.
2. Select the overlap area on the first and second track using the Selection Tool;
3. Choose Effects → Fading → Crossfade Tracks. Set your desired settings or leave everything at default.
   

   

4. Select all tracks: Ctrl+A (Windows) or Cmd+A (Mac). Go to Effect → Volume and Compression → Normalize… Configure your desired parameters or leave them at default.
   

   
   

5. Select all tracks, go to Tracks → Mix → Mix and Render. You’ll get one merged track.
6. To save the file, click File → Export Audio, choose On your computer. Select the format and settings.
