Add background music to a voice recording

TutuAudio places background music under your voice and ducks it automatically — lower while you speak, back up in the pauses. The music loops or fades out to match the length of the voice. Processing is local with no upload; free, no sign-up. No music library is included; to generate music with AI use TutuSound, and to score a video use TutuCut.

MP3, WAV, M4A, AAC, FLAC, OGG, WebM and the audio in MP4 videos

Everything runs in your browser — the file never leaves this device

Drop in a recording and a music track — the music automatically makes room for the voice.

FAQ

What if the music is longer or shorter than the recording?
No manual trimming needed. Longer music fades out at the end; shorter music loops, so it ends up exactly as long as the voice.
Can the music get quieter when I talk?
Yes — that is auto-ducking. The music drops when speech is detected and comes back in the pauses. You can still set the overall music volume yourself.
Are my recording and music uploaded?
No. Mixing happens in your browser; the files never leave your device.
Do you provide background music?
No, bring music you have the rights to use. To generate a track with AI, try TutuSound; to add music to a video, use TutuCut.
Is it free? Do I need an account?
Free, no account, and no watermark on the export.
