Install auto-tune compatible software on your computer. Some of the commonly used compatible software programs include Ableton Live, Apple Garageband, Acoustica Mixcraft, Audacity and Adobe Audition. For a list of all compatible programs, please review the Antares Software Compatibility information.
Download the Antares auto-tune plugin from the Antares website. Install the plugin according to the directions on the site.
Open your Antares-compatible music software program. Make sure that auto-tune installed correctly by viewing the plugins in your software program; for most programs, plugins will be listed under the DirextX effects menu. If auto-tune does not appear in your list of plugins, it's possible that you are using an incompatible program or that the plugin did not install correctly.
Create an auto-tune effect in your music software program. This can be achieved by loading the auto-tune plugin in your music software program and editing the auto-tune settings to achieve the effect you desire.
Load any sound recording into your music software program by recording it directly to the program or loading it from a preexisting file. Apply the auto-tune effect you created with Antares auto-tune software to your sound recording. This final step will vary depending on the music software you are using, but generally you apply your auto-tune effect by checking an "apply effect" box in your music software program after your sound recording has been loaded.
