Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano). Pitch correction devices do this without affecting other aspects of its sound.

Pitch correction is a form of pitch shifting and is found in software such as Auto-Tune and Melodyne to correct intonation inaccuracies in a recording or performance. Pitch shifting may raise or lower all sounds in a recording by the same amount, whereas in practice, pitch correction may make different changes from note to note.
The processor slightly shifts pitches to the nearest true, correct semitone (to the exact pitch of the nearest note in traditional equal temperament). Auto-Tune can also be used as an effect to distort the human voice when pitch is raised or lowered significantly, [9] such that the voice is heard to leap from note to note stepwise, like a ...
Three years before Celemony was founded, Peter Neubäcker was working on a research experiment with sound. This experiment later turned into the Melodyne pitch correction product. Melodyne has become a tool which is used by a large number of professional record producers worldwide to tune and manipulate audio signals, typically a singer's vocals.
While wow is perceived clearly as pitch variation, flutter can alter the sound of the music differently, making it sound ‘cracked’ or ‘ugly’. A recorded 1 kHz tone with a small amount of flutter (around 0.1%) can sound fine in a ‘dead’ listening room, but in a reverberant room constant fluctuations will often be clearly heard.
Since absolute pitch is rare in European musical culture, [1] claims that any particular musician possessed it are difficult to evaluate. Among composers of the Baroque and Classical eras, evidence is available only for Mozart , who is documented to have demonstrated the ability at age 7. [ 1 ]
Some concerts use pitch correction effects (e.g., AutoTune), which electronically correct any out-of-tune singing. Mixing consoles also have additional sends, also referred to as auxes or aux sends (an abbreviation for "auxiliary send"), on each input channel so that a different mix can be created and sent elsewhere for another purpose.
