Organ Tuner

This app is only for professional pipe organ builders and technicians. It addresses the special tuning needs of building and maintaining pipe organs.

Notable features:

* Covers the note range of C0 (32' pipe) to C9 (1/16' pipe)
* Handles mutation ranks (Quint, etc.) and Celeste ranks
* Built-in compensation to track temperature changes
* Calculates pipe cutoff for trimming new pipes to length
* Optional connection to Bluetooth temperature sensor
* Precision strobe-like display for very precise tuning
* Accurate to 0.02 cent
* Provides many historical temperaments for period music
(See our support web page for a complete list.)
* Switches notes automatically up to 4 notes away
* Provides a versatile display of the frequency spectrum

Organ Tuner has two different displays that are visible at once. One is the strobe-like Phase Display. This is a band where black squares move left or right. You tune to make the squares stop moving. The other is a Spectrum Display. This is a graph that shows a peak for every pitch present in the sound. You tune to make a peak in the graph move to a central red line. Having both the Phase Display and the Spectrum Display visible at once gives you a more complete picture of the tuning than any single spinner-type or needle-type display.

A detailed user's manual is available at our support web page. You should download and read this manual before buying this app.
