Auto-Tune

Auto-Tune is a computer program for the subsequent pitch correction of digital music recordings. It was introduced in 1996 by the U.S. company Antares and was for some years as a standard tool of music studios for the correction of vocals, so for example, to bring a melody intoned wrong track on the right octave. The term auto-tune is often used as a synonym for pitch correction systems from other manufacturers, of which there are many. The deliberately used as a sound effect, sharply increased pitch correction is made ​​famous by the song Believe by Cher in 1998 and is therefore often referred to as the Cher effect.

Operation

Auto-Tune is one of the music effects. The program analyzes the pitch of a monophonic ( unanimous ) audio signal ( usually vocals), examines whether and how far the identified frequency is removed from the next correct semitone a given mood, and pulls ( pitcht ) the signal if necessary to the correct pitch. To make the intervention in the audio sound low and the result as natural as possible, you can see the correction to certain pitch limit (eg, the tonic of a key ) and pretending to correct different tones only a determinable percentage. Because the system vibration smoothes pitch corrected or eliminated altogether, can create artificial vibration for long sustaining tones with Auto-Tune.

The speed at which the signal is corrected to the correct frequency is selectable in autotune. If the correction speed is very high, get glissandi unnatural gurgling, mechanical -sounding sound skips. This effect is sometimes used deliberately, such as with the hit single Sensual Seduction by Snoop Dogg or well known from Believe by Cher.

The U.S. rapper BoB in 2009, a song about Auto-Tune written, in which he criticizes the now frequent use; this effect has been used very clearly audible.

Hailing from the U.S. as rapper Eminem dedicated a year later some parts of its originating from the album "Recovery" songs " Cold Wind Blows" this issue. It also highlights the widespread use of the correction program is treated.

The American nu-metal band Limp Bizkit produced the title " Autotunage " for her fifth studio album " Gold Cobra". This use of the effect is parodied by itself corrects the pitch using the program in an exaggerated manner.

In 2011, the German rapper Kollegah fell for the frequent and sometimes inappropriate use of Auto-Tune passages on his album " Boss Aura " in the criticism.

The German hip- hop group The Orson glorified in the fourth verse of their song "Now" the use of the Auto-Tune effect by the U.S. rapper Lil Wayne and Kanye West.

Many artists today work with Auto-Tune; you can see the post on unnatural, sawing sound of the voice on sustained notes.
