Bieber Needs Vocal-Tuning Software Help

Justin Bieber admitted that his vocals didn't have perfect pitch and needed studio help.

The pop star told Q magazine, "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."

Melodyne is a digital audio pitch correction software and has been used by professional record producers widely.

The honest teen singer is now promoting the second single "As Long As You Love Me" featuring Big Sean following the big success of first song "Boyfriend."
