Tighten vocal layers online — tune and line up your takes
Quick answer Record the same line a few times, upload the takes, and get one stacked vocal that is in the same key and starts together.
Add 2–4 takes of the same line. They are tuned to one key, lined up with the first take and mixed into a wide stack. Max 90 seconds per take. 15MB per file (Pro: 20MB).

Double-tracked and stacked vocals sound fuller than a single take, but only if the takes agree. When one take is a little flat and another starts a fraction late, the stack sounds smeared instead of wide. This tool fixes the two things that matter most: it pitch-corrects every take to the same key and scale, and it lines each take up with the first one.
Upload 2 to 4 recordings of the same line, ideally sung against the same backing track or click so the phrases start at similar times. The first take is the timing reference. The others are shifted (up to one second either way) so their phrases begin with it, tuned to the same scale as the first take (or a key you choose), matched in loudness, and panned left and right to build width.
Know what it does not do. Timing is aligned with one shift per take, so if a singer speeds up or slows down inside a take, that drift stays. The stack also needs takes of the same part; different melodies or lyrics will not line up. For the best result, record dry (no reverb or music) and denoise noisy takes first.
Output is a stereo file with the takes mixed together. If you want to mix it over a backing track, use the Audio Mixer; for a single take, use Autotune.
How it works
- Record 2–4 takes of the same line (dry vocals work best) and add them in order; take 1 sets the timing.
- Pick a key and scale, or leave the key on Auto to detect it from take 1.
- Choose Natural or Hard lock tuning, set strength and stereo spread, and keep alignment on.
- Tap Tighten layers, listen, and download the stereo stack.

Tips for better results
- Record every take against the same backing track or click so phrases start at similar times.
- Dry takes work best — reverb and music confuse pitch detection.
- Choose the key by ear if the vocal is unusual; Auto is a good default for clear melodies.
- Use Natural tuning for a believable stack and Hard lock only for a deliberate effect.
- Takes longer than 90 seconds need trimming first.
Frequently asked questions
Does it fix timing inside a take?
No. Each take gets one overall shift (up to one second) to line up its start with take 1. Drift inside a take is not corrected.
Do the takes have to be the same melody?
Yes. It is designed for repeated takes of the same line. Different parts will be tuned to the same key but will not line up.
How many takes can I add?
Two to four, up to 90 seconds each.
Why is the output stereo?
The extra takes are panned left and right to make the stack wider. Set the stereo spread to 0 to keep everything centred.
Is it free?
Yes within the free daily limit, with no account needed to start.
