Description

Precision Strobe Tuner 1.72

A General Purpose Chromatic Musical Instrument Tuner App with special Temperament and Piano Tuning Functions.

The PST combines a radial Spectrum Display with a classic Strobe Tuner and Note Dial for an ultimate visualization of pitch and tone. The Strobe Display is highly sensitive with response speed that is practically instantaneous and has long been the preferred tool for piano tuners and instrument technicians.

The central Spectrum Display shows the input spectrum wrapped around the Display, with each Octave drawn in a separate color. The Note Dial is marked like a clock with the twelve notes of the Scale. All overtones of the input are shown as peaks in the Spectrum Display pointing towards their corresponding Notes. The Fundamental Indicator Tic on the Spectrum Display shows the Note of the Fundamental along the Note Dial, with the color designating the Octave. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note Indicator.

As the input approaches the desired Note, a Two Group pinwheel pattern becomes visible rotating in the Strobe Display. Fine tuning is accomplished by adjusting to stop rotation. The Strobe Display responds instantaneously to changes in pitch and is extremely sensitive. The outside Strobe Display works just like a classic rotating disk strobe tuner. The Two-Group pattern rotates CCW when the input is flat, and CW when sharp. When the rotation is stopped, the note is in tune.

The previews show a general strobe display demonstration, an example of using the calibration function to measure the accuracy of a tuning fork and an example of guitar string tuning.

The first screenshot shows the display tuning a Guitar Low E string. The Fundamental appears as an Orange peak in the Spectrum Display. This string rings bright, so the overtones are also dominant in the Display.

The second screenshot shows the display for an E 440 Tuning Fork with the Calibration Dial enabled and adjusted. This Fork is 2.9 cent Flat.

The PST also includes a Programmable Temperament Function with 5 user definable banks. The third screenshot shows an example of a Temperament Bank set up to a typical Piano Stretch Curve. This can also be used for tuning alternate temperaments, pedal steel guitar setups, or special guitar intonation systems.

In addition, there are several Special Measurement Banks used for String Inharmonicity characterization and Piano Stretch Curve Estimation. Individual strings can be characterized by measuring the Fundamental and 2nd Harmonic separately. By careful selection of a few representative measurement points, a reasonable smooth fit Piano Stretch Curve can be generated. Any number of measurements can be used.

The final screenshot shows the Input Signal Scope/Spectrum Display Page.

Amazing Accuracy!

I just tried this incredible App for the first time! The App name is very accurate, and SO is the App itself! 😃 As a casual 'guitar player' - rather than a 'guitarist', my guitar is often left unplayed for lengthy periods of time (I know, I know! I'm a bad lad! Lol 😂), the thing is, I have many other interests that take up much of my time! 🙄🙄🙄 So my guitar is more-often-than-not out of tune by the time I get around to playing it again! I had been on the lookout for a good guitar tuner - there's a plethora on the App Store, - but I got this one just 15 minutes ago and it is SUPERB!!! 😊😊😊 Does just what it says it will do, and with tremendous accuracy! Apparently it's great for tuning other instruments also, such as keyboards - although I'm unable to comment further on that, as I don't have a keyboard to try it on! Well done this developer on a GREAT App!!! 😃👌

An excellent tuner

I have never had reason to use the more complicated functions of this tuner, but it has excelled as a quick accurate tuner for guitar and bass. Maybe one day I will get around to tuning a piano, though!

strobe tuner

This app is quite incredible. Perhaps not as fancy as some costing over $300 for the pc, but for the price I am blown away.It is easy to use, very accurate and at this price a complete bargain, have already recommended this app to several friends.
