6 technical support in the unlikely event that you experience a problem using your atr-1, try the following: 1. Make another quick scan through this manual. Who knows? You may have stumbled onto some feature that you didn’t notice the first time through. 2. Check our web page for tips, techniques, o...
Page 7: A Few Words From Dr. Andy
7 a few words from dr. Andy i remember, as if it were yesterday, sitting in my junior high school band, happily playing away on my flute, when i noticed that our conductor was screaming and jumping up and down on the podium. What was this about? Suddenly, i realized she was screaming at me. And just...

9 chapter 1: introducing the atr-1 some background in 1997, antares first introduced the ground-breaking auto-tune pitch correcting plug-in for protools™ (followed a bit later by the vst and stand- alone versions). Here was a tool that actually corrected the pitch of vocals and other solo instrument...
Page 10: A Little Bit About Pitch
10 a little bit about pitch pitch is typically associated with our perception of the “highness” or “low- ness” of a particular sound. Our perception of pitch ranges from the very general (the high pitch of hissing steam, the low pitch of the rumble of an earthquake) to the very specific (the exact p...
Page 11: How The Atr-1 Detects Pitch
11 pitch pitches are often described relative to one another as intervals, or ratios of frequency. For example, two pitches are said to be one octave apart if their frequencies differ by a factor of two. Pitch ratios are measured in units called cents. There are 1200 cents per octave. For example, t...
Page 12: How The Atr-1 Corrects Pitch
12 pitch how the atr-1 corrects pitch the atr-1 works by continuously tracking the pitch of an input sound and comparing it to a user-defined scale. The scale tone closest to the input is continuously identified. If the input pitch exactly matches the scale tone, no correction is applied. If the inp...

13 an example as an example, consider this before-and-after graphic representation of the pitch of a vocal phrase that contains both vibrato and expressive gestures. In the original performance, we can see that although the final note should be centered around d, the vocalist allowed the tail of the...

14 if a performance is quite close to begin with and only requires minor correc- tion (i.E., never more that 50 cents), it’s often sufficient to simply choose the chromatic scale, set speed to about 10 and leave it there. If you are working in the studio to correct an already recorded track, you mig...

15 chapter 2: setting up the atr-1 setting up the atr-1 is a very straightforward. 1. Find a suitable location. The atr-1 is designed to be mounted in a standard 19-inch equipment rack. 2. Confirm that the included power supply is correct for the electricity in your part of the world. If you are not...

16 an important note about monitoring: if the atr-1 is used to pitch-correct an artist’s performance in real time, it is very important that the performer is able to monitor their original signal, not the pitch-corrected signal. Trying to react musically to the processed signal will drive them crazy...
