The pitch correction tool & plugin Melodyne by the company Celemony was released initially back in 2001 & after several versions & updates it remains one of the standards in the industry to perform this task.
Here I share with you a couple of very cool alternatives, one of them free (PC & Linux) by Liuanlin mx & the other very affordable by Waves Audio.
In this video I go through some of the most important features of these vsts, test them & talk a bit about my stance on these type of plugins.
Let me know what you think of these alternatives, what pitch correction vst you use?
