Every note is detected and snapped to the nearest semitone, preserving timing and tone.

Questions before you start
Will it sound robotic?
No — correction is chromatic (nearest semitone) with PSOLA resynthesis, which preserves the natural texture of the voice. Hard-tune robot effects are a different, intentional sound.
What audio works best?
A solo vocal recording. If you only have the full song, run it through the audio separation tool first to extract the vocal stem.
Does it fix timing too?
No — it corrects pitch only. Timing stays exactly as performed.
How long does processing take?
Roughly real-time: a 3-minute vocal takes about 2-3 minutes on the GPU servers.
