Audio mixer — vocals over music
Quick answer Combine an Autotuned vocal with a music bed. Balance levels, loop the instrumental, offset timing, and optional ducking so the voice sits on top.
Mix vocals (e.g. Autotune output) over music (AI beat or instrumental). Loop the bed, balance levels, optional ducking. 15MB per file (Pro: 20MB).
Positive = music starts later. Negative = music lead-in.

After Autotune and the AI music generator, the last step is a proper mix. Upload your vocal (or any lead) and a music track, set levels, and download a single stereo file ready to share.
The mixer can loop a short beat to match a longer vocal, delay either side for alignment, and gently duck the music when the voice is loud so lyrics stay clear.
How it works
- Upload Track A (vocals / Autotune output) and Track B (music / beat).
- Set vocal and music levels in dB. Start with music around −6 to −12 dB under the vocal.
- Enable Loop music if the beat is shorter than the vocal.
- Optional: offset (ms) to align downbeats, and duck music under vocals.
- Export MP3 or WAV.
Who uses this
Autotune + AI beat
Tune a vocal, generate a bed in Music Generator, then mix both here.
Cover / freestyle
Drop acapella over an instrumental download.
Podcast bed
Keep voice high, music low, with ducking so speech stays clear.
Tips for better results
- Normalize or Autotune the vocal first so levels are consistent.
- If the mix clips, lower music gain before boosting the vocal.
- For trap/pop, try music at −8 dB and ducking on.
Frequently asked questions
Does this replace a DAW?
No — it is a quick two-track mix for vocals over a bed. For multi-track projects use a full DAW.
Can I mix more than two files?
This tool is two tracks. Use Merge to concatenate, or mix in pairs.
Will it Autotune for me?
No. Run Autotune first, then mix the result with music.
