Graillon is the most popular free autotune plugin. Luckily there are some decent free alternatives for real-time pitch correction out there. That being said, it’s an expensive plugin, especially if you’re just starting out or just want to experiment with its sound a little bit. If you want the most authentic autotune sound, it’s a good idea to stick with Antares. Travis Scott, Future, Playboi Carti, and many use it as the main effect to shape their vocals. Today, the autotune sound is all over the place in modern rap. After Cher in the late 2000s, T-Pain popularized the effect even further, with other prominent artists like Lil Wayne and Kanye West catching on.
