Spoton

Spoton is the easiest-to-use free autotune plugin. However, that doesn’t make it less useful if you’re looking for quick pitch correction results. The plugin utilizes a simple plug-and-play workflow. Load it on your vocal track, and the pitch will snap to the selected scale as soon as you move the Amount knob. If the resulting vocal is too “autotuned” for your taste, use the Speed knob to make the pitch correction more natural.

You can use the keyboard at the bottom of the interface to define the scale. This will ensure the pitch is corrected to match the notes in your song. Spoton is a simple, fast, and completely free autotune effect. It closely matches the pitch correction quality of Graillon 2 Free Edition while being more straightforward for beginners.
