The “autotune sound” is not one setting. It is two choices: which notes the voice is allowed to hit (the key and scale), and how fast it is pulled onto them (retune speed). Get the key right and everything else is taste.
Pitch correction needs to know which notes are “right”. Ask the producer, look at the project file, or detect it from the beat. Choose the scale (major or minor); if you are unsure, a chromatic setting corrects to the nearest semitone but gives you less of the melodic character.
Clean up noise and clicks first, then tune, then compress, then add saturation, reverb and delay. Tuning after reverb makes the tail warble; tuning a noisy take makes the tuner misread the pitch.
Many rap takes sound “off” because syllables drift from the grid rather than because the notes are wrong. Nudge words onto the beat, especially on repeated patterns and ends of lines, and keep the correction small enough to keep the swing.
Browser-based tuners (Audimee’s free tier, Rys Up’s tool, BandLab’s AutoPitch and similar) are fine for trying the sound on a short clip. Check each one’s limits, watermarks and what they do with your uploaded audio before sending unreleased music. Most online tools get you to a usable melodic sound; they do not match the speed and control of dedicated pitch software.
Classic autotune is pitch correction: detect the note you sang and move it to the nearest note of a scale. It is not generative AI. When people search for “AI autotune” they usually mean one of two things: pitch correction that picks the key and settings for you automatically, or voice-conversion tools that replace your voice with another one.
For rap and melodic vocals, automatic key detection plus fast, key-locked pitch correction is what gives the modern sound. Use the free song key finder to get the key from your beat, then set it in your tuner.
Tunedzy reads the key and tempo from your beat, tunes your take to it with a style you choose (off, natural, a style learned from a reference song, or hard), keeps the natural movement in long notes if you want it, and nudges words onto the beat. You can also paint a section so one line gets hard-tune while the rest stays natural.
It depends on the sound you want. Slower for natural, around 10–30 ms for a modern melodic sound, and 0 for the hard robotic effect.
Yes for the best result. If you do not know it, detect it from the instrumental, or use a chromatic setting as a fallback.
Several online tools and free plugins can give a basic melodic effect. Check limits and privacy; they are fine for experiments but may not hold up for a release.
