Pop sensation Justin Bieber`s vocals tuned by software

Justin Bieber refuses to use Auto-Tune, the popular audio processor utilised by other stars including Britney Spears.

London: Teen pop sensation Justin Bieber says record producers use vocal-tuning software to adjust his singing.

The 18-year-old `Baby` hitmaker is said that he refuses to use Auto-Tune, the popular audio processor utilised by other stars including Britney Spears, but recording studio engineers correct the pitch of his singing with Melodyne software, reported Contactmusic. "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," Bieber said. PTI
