Open your preferred digital audio workstation. Typically, the last edited session opens automatically. If this is not the required session, open the correct session. The precise commands vary slightly according to which workstation you use, but recent works-in-progress are accessible from the file menu. For example, in Logic click "File" and select "Open Recent."
Click on the audio track that has the Auto-tune effect on it. If you can't remember which one it is, play the track and hit the "S" button on each track in turn. This solos the track so you can hear it in isolation, permitting you to better judge which track has the effect.
Click on "Effects" in the channel strip side-chain. This brings up a menu of currently engaged effects.
Click on "Auto-tune." This opens the Auto-tune control interface.
Click "Bypass." This deletes the effect from the audio, returning it to normal.
Open your preferred digital audio workstation.
Click "Effects" in the main menu at the top of the screen.
Open the "Preferences" interface. The method may vary according to which program you use, but this option is typically located in the "Effects" menu.
Open the "VST Plugins Manager" or "Plugins" tab. This opens a dialog box with all of your installed plugins and effects. Auto-tune is a third-party effect that is compatible with multiple digital audio workstations. To make it compatible, the effect is formatted as a virtual studio technology, or "VST" plugin. The Pro Tools platform calls for a Real Time Audio Suite plugin, rather than VST. If you are using Pro Tools, select "RTAS" rather than VST.
Right-click on the Auto-tune folder and select delete.
