📥 Importing Background Music & Sound Effects: The First Step in Mixing!

Now, let’s learn how to import downloaded background music and sound effects into your Audacity project and mix them.

• Importing Background Music & Sound Effects: The simplest way to import music files or sound effect files into Audacity is to click and drag the file directly into the Audacity program. When you drop the file, it will be added as a new track.

⏱️ Adjusting Timing and Length: Creating the Flow of Your Audio Content!

Background music and sound effects must be timed appropriately with the voice (narration) track.

Music may be longer or shorter than the voice, and in some cases, you may only want to use a specific section of the music.

• Adjusting Timing: Drag the music track or voice track left and right with the mouse to adjust its position. For example, you can adjust it so that the voice begins after the music has played for a short while.
• Adjusting Length: To match the length of the music to the voice track, you can delete unnecessary sections, copy and extend necessary parts, or use the track duplication function to adjust to the desired length.

🎚️ Volume Adjustment: Finely Controlling Background Music Volume!

The volume of background music should be adjusted appropriately so that it is not too loud compared to the voice volume.

If the music is too loud, the voice will be drowned out; if it’s too quiet, the effect will be diminished.

• Utilizing Loudness Normalization:

  Select the music clip, then go to ‘Effect’ > ‘Volume and Compression’ > ‘Loudness Normalization’ menu.
  In the LUFS input field, enter a value smaller than the -15 LUFS standard for the voice track (e.g., -26 LUFS).
  This value is empirically suitable for background music volume, and you can apply this value to any music file to get an appropriate background music volume relative to the voice.
  It is recommended to preview the sound and adjust before applying the value.

🧹 Cleanup: Fade In/Out and Crossfade: The Secret to Natural Transitions!

Naturally process the beginning and end of the background music to avoid unnatural cuts.

• Fade In/Out:

  Used to prevent music from starting or ending abruptly.
  Apply fade in to the beginning of the music file and fade out to the end, so the sound gradually appears or disappears.
  If you cut the music in the middle and it sounds choppy, apply a short fade out to that section to make the sound disappear naturally.

• Crossfade:

  An effect where fade out and fade in overlap, used to naturally connect two audio clips.
  For example, if the voice file is very long and the music file is short, requiring the music to loop, duplicate the music track, move it to the appropriate position, and apply a crossfade.
  This creates a seamless transition of the music. Also, when transitioning between two pieces of music with different atmospheres, crossfade can be used to create a smooth transition.

💾 Final File Save (Export Audio): The Perfect Finalization of Your Audio Content!

Once all editing and mixing work is complete, you must export the audiobook as a final file.

• Path: Select ‘File’ > ‘Export Audio’ > ‘Export to Computer’.
• File Settings: Specify the file name and select the folder to save it in. It is recommended to convert the final file format to MP3. The final audiobook with music inserted is typically saved as stereo. The sample rate should be 44100Hz, the bitrate mode Constant, and the quality 192kbps.
• Save Complete: After setting the options, click ‘Export’ to generate the final audiobook file (mp3). You can then share this file or upload it to a platform.
