Pitch Correction for Voice or Solo Instrument

Hailed as a "Holy Grail of recording" by Recording Magazine, Auto-Tune is the worldwide standard in professional pitch correction. It corrects intonation problems in vocals or solo instruments, in real time, without distortion or artifacts, while preserving all of the expressive nuance of the original performance. Auto-Tune offers audio quality so pristine that the only difference between what goes in and what comes out is the intonation.

The precision by which Auto-Tune detects pitch is extraordinary. At a frequency of 400 Hz and a sample rate of 44100, the Auto-Tune DSP algorithm computes the pitch to an accuracy of .0001 samples per cycle, or .0004 Hz. At this resolution, the very question "What is pitch?" becomes relevant. That is, as the pitch of typical performances continuously change, the amount of variation in pitch, even over the time of a few cycles, changes greatly in comparison to the accuracy by which Auto-Tune computes pitch.

The pitch computed by Auto-Tune is a mathematical estimate of the cycle period repetition rate over the last two (or sometimes the last four) cycles.
