Waves UltraPitch

For stereo chorusing, doubling, parallel harmonies, vocal slap and spread effects, the UltraPitch pitch shifter and harmonizer plugin is a processing powerhouse.

Ultrapitch is a sound design tool that spans the range from simple pitch shifts to complex, 6-voice harmonies with formant changes and panning. In addition to voice, it works with a variety of monophonic sources, and includes detection profiles for different voice characters as well as bass. You can even transform the spoken word into different personalities—ideal for voicing multiple roles in audiobooks and podcasts, or creating robot voices. Ultrapitch is your key to vocal creativity.
