How to Add Audio to Video with Steps
Step 1: Add audio and video files to the program
After downloaded and installed Wondershare Filmora, you can either click Import on the primary windows and select audio and video files from your computer, or simply drag and drop audio and video files to the User's Album.
Drag the audio and video files from User's Album and place them on the respective tracks of the Timeline. This way, the audio file(s) will be merged into the video. Note that the original audio track will be kept.
Step 3: Add voiceover to video
Instead of adding music to video, you can also add voiceover to video. It's a fun way to add narration or complementary audio to video. To do so, just click the Record button on the toolbar above Timeline, the Record dialog will appear. Click the red Record button and you can start to talk in 3 seconds. The voiceover will be added to User's Album as well as Timeline when completed.
Step 4: Replace audio track of video
This is similar to add audio to video. Just an extra step is required: delete the video. To do so, right click the video you want to replace audio in it, and select Audio Detach. After that, delete the audio file from the track. As described above, you can then drag and drop a new audio file from User's Album to Audio track.
Step 5: Adjust the audio file (optional)
A variety of audio editing tools are available: set volume, speed up, slow down, change pitch and add fade in/out effect. To change the settings, just double click the audio file on the timeline and drag the slide bar. Hit "Return" to confirm the settings and go back to the main interface.
Step 6: Export video with new audio track
When all is ready, click "Create" and select "Format". From the list, choose any format you want as the output format. If necessary, also change the advanced settings. Finally, click "Create" button to export a new video file to the specified folder on computer. Besides export video your computer, you can also create video for devices like the iPhone, iPad, iPod, directly upload video to YouTube, or burn to DVD for playing on TV. All in one video editor, no extra software required.
