AceMovi also permits you to import local audio from your device. Just as importing AVI video, you can click the "import" button to import the audio and then add it to the timeline or directly drag the local audio to the timeline.

Step 4Adjust the audio added to AVI

After adding music to AVI video, click on the music and adjust it to better match your need. On the upper right panel, you can adjust the volume of the audio clip. Or you can directly type in the volume. By dragging the markers, you can fade in and fade out the audio.

What's more, if you find the background audio of AVI video contains some background noise, you can use the Denoise feature to filter out the noise so that the audio will be clearer. Additionally, TunesKit AceMovi offers you a built-in equalizer with 6 presets to adjust the frequency of the audio.

Step 5Match the audio with AVI video

Step 6Export AVI video
