Equipment review: Antares Auto-Key mobile app


Nothing can kill a good melody like being out of tune. Seasoned songwriters and performers know this, and that’s why Antares, a Santa Cruz-based company, created their famous Auto-Tune software.

For more than 20 years now, studio engineers and producers have relied on this technology to perform pitch corrections in the studio and in concert to give artists the best sound. Now Antares has released a handy mobile app for iOS devices called Auto-Key Mobile that anyone can use to quickly and easily detect the key to any audio source – and it’s free, so of course I had to try it.

To begin with, I picked up my download from the App Store and answered “yes” to the only question presented during installation to allow the app to use the iPad mic. Other than that, the only thing users need to do is create an account for Auto-Key. Unlimited use of Auto-Key is free and no purchase is required, but users must create an account and agree to Auto-Key’s terms of use; all typical of an iOS app installation.

Using the automatic key couldn’t be simpler; You don’t really need instructions. All you need to do is press the big Auto-Key button (cleverly surrounded by a colored circle of fifth wheels listing all the possible keys of your song or music sample) and Auto-Key grabs a sample of 3 to 10 seconds to analyze to find the most probable key according to the notes that he can identify and associate with a scale. I took an acoustic guitar and strummed two chords on my iPad and Auto-Key called the “D” key correctly. You can check the results with Auto-Key’s built-in software keyboard.

I tried adding background noise (one of the few things that can interfere with lag detection), but Auto-Key turned out to be quite smart. The app has always worked well to find the right key. Other things that can interfere with pitch detection are what you can expect: detuned instruments, samples with more percussion than tonal instruments or vocals, and other samples without much harmonic content.

Something I didn’t expect is that the software is able to accurately guess examples of minor keys (notes in a minor scale are also shared by its relative major scale). But, again, the app was up and running. That said, Auto-Key’s key decisions are really the most likely, but even classical composers can get stuck calling keys when there are dense note groups or just a few harmonies. Barring any odd examples, Auto-Key does exactly what it was designed to do: help you find a key quickly.

If you’re like most of us, you’ve wished for a perfect pitch at one point or another. Now there is a mobile app you can have in your pocket that will tell you what you need about the keys when you need them. I can see that Auto-Tune Mobile is useful for songwriters, casual musicians and even highly technical sound engineers and producers who need to quickly set up digital processing to automatically tune tracks because Auto-Key Mobile communicates. directly with the company’s Auto-Tune or Harmony. Engine software.

You can find out more at www.autotune.com or just download Auto-Key Mobile for free and have a try. It is currently only available for iOS devices, but versions for Android and Windows devices are promised soon.
