🎤 The Two Types of Auto-Tune: Live and Studio

This paragraph delves into the two main types of auto-tune: live and studio. The speaker starts by discussing the live auto-tune, which is the strict sense of auto-tune. It tunes the voice in real-time as the performer sings, adjusting the frequencies in milliseconds to correct the pitch. This type of auto-tune is sometimes used by artists during live performances due to its rapid response. The speaker then transitions to explaining the studio version of auto-tune, which is software for editing pitch and intonation. In this case, the correction is not immediate, and the speaker demonstrates the studio auto-tune software, showing how they can manually adjust the pitch of their digitized voice. The paragraph also provides an interesting origin story for auto-tune, explaining how it was originally invented in 1996 to study petroleum before being adapted for music the following year. The speaker concludes by acknowledging criticism about auto-tune potentially masking poor singing but also explaining how it's often used intentionally to create a particular robotic vocal effect.
