Autotune is a technology that makes it possible to modify the pitch of an audio recording. The purpose of autotune is to make sure the vocalist’s voice matches up with the music they are singing, and if done well, it can make for an amazing sound. The original autotune was created by Japanese musician Seiichi Miyake in 1997 when he was trying to create a device that would change synthesizer sounds on different musical scales and chord progressions.
Autotune corrects out of tune notes by matching them to their nearest semitone, which can be heard in all genres of music including pop, country, R&B and more. It’s often used in hip-hop songs to make it sound like the vocalist has perfect vocals.
In other words, Autotune is a type of audio processor that analyzes sounds in real time and corrects pitch, timing, and other qualities to produce more accurate recordings. It can be found on everything from karaoke machines to recording studios to cell phones.
This form of software has been used by artists such as Britney Spears, Akon, Kanye West, Cher Lloyd and Justin Bieber. That also includes Billie Eilish (although she doesn’t always or even often use it).
