Hildebrand had come up with the idea for a vocal pitch correction technology on the suggestion of a colleague's wife, who had joked that she could benefit from a device to help her sing in tune. 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). We have competent singers so 99.99% of the time, the tuning corrects a slightly sharp or flat note to the desired pitch.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. We’ve kept ours in the chromatic mode, which will correct the pitch to the closest chromatic note. Any further tinkering is all to need or taste. You can set them to anything you want, but we’ve found that the default settings already sound pretty natural. Once your in the settings, you can play with everything from the tuning mode to the speed of the note transition. Now you can modify your pitch correction for your desired effects Once it’s open, hit the ‘wrench’ icon to open up your settings Go into the Ableton Plug-Ins tab and drag Waves down into the screen Now that you’ve made sure all of your channels and routing are correct, you’re ready to dive into Waves. Once you’ve done that in the preferences, the signals will go back through the Dante Network and into the console It will give you access to all of the inputs/outputs, and you can modify which channels you want You’ll be able to see the Dante Sound Card plug-in in Ableton Series will be helpful if you don’t already have some of this gear. I’ll go more in-depth in the next section, but the Ultimate Guide to Worship Tech 3-pt. I’m going to give you a brief overview of the gear you’ll need to set up auto-tune. A part of gospel-centered worship is crafting the best ministry we can and we believe that auto-tune has a place in that vision. Not everyone sings perfectly on pitch all the time and auto-tune is able to take those small inconsistencies and correct them in a natural, non-artificial sounding way. It can ‘tune’ them up to make dense, difficult harmonies that much better. Auto-tune is just a tech-savvy way of eliminating small mistakes or distractions. We’re all for excellence in worship, and we encourage our band to practice and be the best that they can. We know that auto-tune can be a divisive issue, but here are a couple things to keep in mind:Īuto-tune should never be used to compensate for poor singingĪuto-tune is not, and should not be used to ‘make up’ for wildly incorrect pitches, it is only there to give that extra push if necessary.
