Pitch correction is a technology used in music production to adjust the pitch of vocal and instrumental recordings. It helps ensure that notes sung or played are in tune, making the final product sound more polished. This process can be applied subtly to enhance a performance or more dramatically to create unique vocal effects, often seen in pop music. One popular tool for pitch correction is Auto-Tune, which allows producers to fix off-key notes in real-time. While some artists use it to achieve a specific sound, others rely on it to correct minor imperfections, ensuring that their music resonates well with listeners.
