1. Add Background Music

Adding background music can drastically change the tone of your video. Filmora provides a royalty-free music library you can access within the program, or you can import your own music.

Here are a few ways to add background music to your videos.

Note: the music and sound effects found within Filmora are for personal, non-commercial, use only. Click here to learn more >>

Import Music from your Computer: Select an audio file that's stored on your PC and bring it into Filmora.

Click the button above the Media Library panel to browse for audio files in your computer. When you find the song or other audio file you want, select it and import it into the Media Library. You can also drag and drop audio files into the Media Library. From there, you can drag and drop your audio into an Audio Track in the timeline.

Using Music from Filmora: choose a song from Filmora’s royalty-free audio library and use it for free. The audio library has 50 songs divided into five categories: YOUNG & BRIGHT, TENDER & SENTIMENTAL, ROCK, FOLK, and ELECTRONIC. There are also sound effects available under SOUND EFFECT.

Here are two ways you can add music from the audio library to your video:

• Select a song, right-click, and choose Apply
• Drag and drop the song into the Timeline

Once you've added your music, double click on the music in the timeline to bring up the Audio window. In this window you can adjust the volume and pitch of the music. You can also apply fade-in or fade-out effects and use their sliders to determine how long they will last.

Note: you can add up to 100 audio tracks.

2. Split Audio

In the timeline, move the playhead to the point in your audio clip where you want to split it. Then, right click on the clip and select "Split" or click the Split button in the toolbar above the timeline.

3. Adjust Audio

To make adjustments to your audio, double click on the audio clip you want to work on in the timeline to open a panel with adjustment sliders for volume and pitch. You can also apply Fade in/out effects and adjust their lengths here.

Another tool you’ll find in this panel is Denoise, which is a feature that can remove background noise from your audio clips.

For a more advanced audio editing experience, you can also access the Audio Equalizer from this panel. You can choose from presets or make manual adjustments by clicking ‘Customize’.

Give it a listen when you are done and, if you’re not happy with the results, click Reset to start over.

4. Mute Video Clip

If you are using a higher quality version of the audio which you detached, drag it to an audio track underneath the separated audio and make sure the wave forms line up to sync it. Then, select the detached audio clip and delete it.

10. Adjust audio volume

There are several ways to adjust the volume of your audio in Filmora:

To adjust the volume in the Audio panel: after you drag and drop the audio file into the timeline, double click on it to open the Audio panel.

In the volume section, drag the slider up or down to adjust the volume.

To adjust the volume in the timeline: Move your mouse over the volume band in the audio clip and the pointer will change to a hand icon .

Drag the handle up to increase the volume and drag it down to decrease the volume.

If you want to adjust the left/right balance, enter a numerical value or drag the knob in the Balance circle. A numerical value of 0 means the audio is balanced, -100 is all the way to the left and 100 is all the way to the right.

If you need to have the volume increase and decrease as the clip plays, use audio key frames.

To add an audio key frame, go to the timeline and move the playhead to the location where you want the change in volume to start.

Double click the audio clip to open the Audio control panel and click the key frame button.

Next, move the playhead to where you want the volume adjustment to end and click the Keyframe button again. Now you’ll be able to rag the volume envelope (the line between your two keyframe dots) to adjust the volume of that section of your audio clip.

11. Fade Audio In or Out

After adding your audio to the timeline, double click on it to open the Audio adjustment panel.

Set fade in and fade out effects by dragging the sliders or by entering how many seconds a fade effect should last.

You can also use the fade icons at the left and right edges of the audio waveform areas to quick fade in and out.

At the beginning of the audio clip, drag the fade in maker to the right to apply a fade in effect.

To apply a fade out effect, go to the end of the audio clip and drag the fade out maker to the left.

The further you drag, the longer the fade effect will last.

12. Adjust Audio Speed

You can also go to the master section and drag the Master volume slider upward or downward to adjust the master volume higher or lower. After you’ve made adjustments, click the Play button to hear the results.
