MAutoPitch

MAutoPitch is a free pitch correction plugin for Windows and macOS. MeldaProduction included several bonus tools, such as stereo width adjustment, automatic gain control, and a limiter. MAutoPitch is flexible and easy to operate, with adjustable speed, range, scale, and depth. The interface lets you define the notes that the vocalist is “allowed” to sing, making it almost impossible for the vocal to go out of tune. I often use the included stereo-widening feature because it sounds excellent on backing vocals.

The ability to control the formats is another big plus. If you don’t like the default color scheme, choose one of the alternative skins. MeldaProduction did a great job with the interface design, and it’s easy to customize to your liking.
