The 18-year-old says recording bosses uses Auto-Tune, the popular audio processor utilised by other stars including Britney Spears, to correct the pitch.
“I don’t use Auto-Tune. They tune my vocals – they use Melodyne. But every artist uses Melodyne. Not every artist, but 99 per cent of artists. I like the sound, the perfectness of tuning in the record. No one has completely perfect pitch,” contactmusic.com quoted Bieber as saying.
