Peterson iStroboSoft - Manual (Page 2)

Sharp/Flat Indicators
These indicators will illuminate when the note is so far out of tune it is difficult to
determine whether the note is sharp or flat. As you come closer to being in tune
(usually less than +/- 10 cents), they will turn off and allow you to use the strobe
display as your guide.
Full Screen and Flip Mode (iPad Excluded)
The strobe display can be maximized for easy viewing at a greater distance by
"opening" your fingers across the screen. The full size strobe mode will only display
the strobe window, note/octave window and cents display. Options will not be
accessible in full screen mode.
To go back to normal view, "pinch" your fingers across the screen.
Regardless of full screen or normal view, the strobe display will "flip" to the
orientation of your device allowing you to place the device in a horizontal or
"landscape" manner for greater positioning possibilities in your tuning area.
As you turn or flip your device, the strobe screen will follow and re-orient itself for
proper viewing.
Noise Filter (iOS Only)
Use the noise filter (located on the main screen) when utilizing an external mic or
clip-on tuning device to help reduce the effect of extraneous environmental noise
during tuning. The filter will take 3-5 seconds to run. During this time, it is important
that no noise be made as the filter will attenuate the captured frequencies and your
tuning measurements may be incorrect as a result. Noise includes any instrument
handling noise or sounds being picked up by an external microphone.
The noise filter is generally not required for devices with a line output level such as
electric guitars or electric bass.
Engaging the noise filter will also reduce mains hum when tuning with your device
plugged in or on a dock (during charging).
Note: The noise filter will be engaged every time you open iStroboSoft if it is
closed with this feature enabled.
Input Boost (iOS Only)
The input boost will raise all input frequencies by +24dB. Use it when utilizing a clip-
on tuning device that offers low output or when tuning acoustic instruments with a
microphone and having difficulty obtaining a solid reading.
Enabling the boost will facilitate measurements that would normally pose a difficulty
to measure accurately.
The input boost is generally not required for devices with a line output level such as
electric guitars or electric bass.
Note: The input boost feature will be engaged every time you open
iStroboSoft if it is closed with this feature enabled.
Important: Watch the input LED meter (main page) to make sure the input signal is
