Īccording to the Auto-Tune patent, the referred implementation detail simply consists, when processing new samples, of reusing the former autocorrelation bin, and adding the product of the new sample with the older sample corresponding to a lag value, while subtracting the autocorrelation product of the sample that correspondingly got out of window. Music industry engineers had previously considered the use of autocorrelation impractical because of the massive computational effort required, but Hildebrand found a 'simplification changed a million multiply adds into just four.

His method for detecting pitch involved the use of autocorrelation and proved to be superior to earlier attempts based on feature extraction that had problems processing certain aspects of the human voice such as diphthongs, leading to sound artifacts. Over several months in early 1996, he implemented the algorithm on a custom Macintosh computer, and presented the result at the NAMM Show later that year, where 'it was instantly a massive hit.' research engineer who specialized in stochastic estimation theory and digital signal processing. History Īuto-Tune was launched in September 1997 by Andy Hildebrand, a Ph.D. Instruments such as the Peavey AT-200 guitar seamlessly use Auto-Tune technology for real time pitch correction. Īuto-Tune has become standard equipment in professional recording studios. Auto-Tune can also be used as an effect to distort the human voice when pitch is raised or lowered significantly, such that the voice is heard to leap from note to note stepwise, like a synthesizer. The processor slightly shifts pitches to the nearest true, correct semitone (to the exact pitch of the nearest note in traditional equal temperament). MAutoPitch is a autotune plugin for auto-tuning and pitch correction designed for vocals and other mono instruments.Auto-Tune is available as a plug-in for digital audio workstations used in a studio setting and as a stand-alone, rack-mounted unit for live performance processing. Best Free Autotune VST Plugins for Windows & Mac Meldaproduction – MAutoPitch In the second part of this article, we will briefly introduce some of the best paid autotune software on the market.

This type of program has been around in the music industry for some time and is widely used in indie, rock, RnB, pop, and many other genres.

It is usually used for vocals to obtain a perfect pitch sound, but can also be used for a wide range of instruments, melodies, or chords. It is computer software that corrects out-of-tune vocal performances in post-production.Īn autotune plugin raises or lowers a particular note’s pitch by changing its vibration speed. But in fact, it is first referred to as Auto-Tune, developed by Antares Audio Technologies.
