Mix Vocals Over a Beat

Drop a beat and your own vocal take, line them up, balance them — then master the mix. Recorded your vocal over the beat playing out loud? Line up with the beat finds the timing for you. Already-aligned stems from Suno and Udio work too. Runs entirely in your browser: no signup, no upload.

How to mix your vocal over a beat

Suno and Udio export stems that all start at the same moment, which is the whole reason this is simple: there is no timeline to fight, no clips to nudge into place. Drop them in and they are already lined up. What is left is the part that actually changes how a song feels — how loud each part sits, where it sits across the stereo image, and how the song ends.

  1. Drop every stem in at once. Vocals, drums, bass, and whatever else came out of the export.
  2. Set the balance first. Get the vocal sitting right against the drums before touching anything else. Use S to solo a lane and M to mute it.
  3. Pan for space. Keep the vocal, bass and kick near the centre. Spread doubles, guitars and keys outward.
  4. Fade the ending. AI-generated songs often stop abruptly. A one to three second Out fade fixes that better than anything else you can do in a minute.
  5. Master the mix. Hand it straight to the mastering page — loudness, tone and true-peak safety happen there.

Why there is no recording yet

Recording over a backing track in a browser needs latency compensation: the gap between what you hear and what the microphone captures has to be measured and subtracted, per device. Without it a vocal lands late by a noticeable fraction of a beat — and by a different amount on every phone. Shipping that would waste your take, so the Finisher works with stems you already have while the measurement side is built properly.

Where your projects live

On your device, in this browser. Your project reopens automatically the next time you come back — stems included. Nothing is stored on a server, which is also why there is no signup. The trade-off is that browsers reclaim site storage — Safari after roughly a week without a visit. Three ways to keep work safe: Export .tgproj, which packages the project and its stems into one file you own (and is how you move a project to another device or computer); add TrackGleam to your Home Screen, which exempts it from that cleanup; or Bounce to WAV and keep the mix itself.

Lane limits, and why they exist

Audio is heavy once decoded — about 22 MB per minute of stereo. The Finisher tells you the budget up front and refuses an import that would exceed it, rather than letting the tab die mid-project. Desktop allows up to twelve lanes; phones get four, because a phone browser will be killed by the operating system long before a laptop notices.

Frequently asked

Does it change my audio quality? The mix is a straight sum of your stems with the gain, pan and fades you set — nothing else is applied. The bounce is a 24-bit WAV.

Can I add EQ or compression per lane? Not in the Finisher. Keeping every control to simple arithmetic is what makes the bounce exact and fast. Tone shaping happens at the mastering stage.

Will the master be the same length as my mix? Close, but not always identical — mastering trims dead silence from the head and tail by default.

What if my mix clips? The Finisher tells you the peak after bouncing. If it is clipping, pull the loudest lanes down a little; mastering has more to work with when there is headroom.
