Pitch Doctor combines an extraordinarily smooth pitch-shifter with an advanced intelligent pitch analyzer to create the ultimate pitch correction tool. When an out-of-tune performance is a problem, PitchDoctor is nothing less than a session-saving miracle. Simply enter the desired key and scale, and Pitch Doctor automatically adjusts the intonation of any out-of-tune notes. Because Pitch Doctor is the only intonation correction plug-in with total automation and PurePitch's formant-preserving quality (no chipmunks!), it's the only choice for truly challenging correction work. And it's only available for Digidesign's TDM hardware system.
