Add background music or voiceover to video with volume control
Meicut's audio mixer puts music or a voice-over on any video. Replace the original sound or mix the new audio in at the volume you choose, and hear the result in the preview before you export.
Audio blocks sit on a timeline: drag each one to where it should start, stack several tracks, and set the volume of every block separately. Accepts MP3, WAV, OGG, M4A, AAC, FLAC and WMA.

Common audio needs
Put background music on a clip
Travel footage and montages come alive with a track underneath. Add the song, set the balance against the original sound, and preview until the mix feels right.
Record a voice-over for a tutorial
Narrate the steps, add the recording as a block, and drag it to the exact moment the walkthrough starts. Mix mode keeps the original sound under your voice; replace mode removes it entirely.
Layer music and voice together
Blocks on separate tracks play at the same time: music underneath, narration on top, each with its own volume. Drag either one to fine-tune the timing.
Replace noisy original sound
Wind and crowd noise ruin otherwise good footage. Replace mode mutes the original track completely, so only your added audio is heard.
Add sound effects at the right moments
A whoosh at a transition, a ding at the reveal: drop short effect clips in as their own blocks and drag each one to the frame where it belongs.
Replace or mix
Replace
The original sound is muted entirely and only your added audio is heard. Right when the original track is noise, or when the footage was shot silent anyway.
Mix
Your audio plays on top of the original sound. Set the block volume to balance the two: music low under dialogue, or ambience low under a voice-over.
Frequently Asked Questions
How do I add music to a video?
Upload your video, then choose an audio file such as an MP3. Adjust the volume balance between the music and the original sound, preview, and export the finished video.
Can I replace the original sound completely?
Yes. Switch to replace mode so the original audio is muted and only your added music or voice-over is heard.
What audio formats can I add to a video?
You can add common audio formats such as MP3, WAV, OGG, M4A, AAC, FLAC and WMA to videos in MP4, MOV and other common formats.
Can I add more than one audio file to a video?
Yes. Add several audio blocks, place each on the timeline where it should start, and set a separate volume for every block. Blocks on different tracks play at the same time.
Can I control where the music starts?
Yes. Drag the audio block along the timeline to set when it starts. The preview plays the mix, so you can hear the timing before you export.
