Dombra Tuner 1.2

The user interface of this tuning application is both intuitive and effective, featuring noise filtering capabilities that facilitate the tuning of two strings seamlessly during the app's activation. To initiate the process, users select the desired frequency from the top of the screen, followed by choosing the specific tuning in the middle section. When a Dombra string is plucked, the pitch is displayed on the panel for each string, indicating whether the pitch is high or low.

Function Description:

• Calibrate Piano Sound: Users can click on an open string to calibrate its sound with their Dombra; the reference standard is Piano Sound A4=442.
• A4 Frequency Adjustment: Users have the option to choose frequencies ranging from 428 to 452 for the A4 string.
• Precision Tuning Scale: The application operates on a scale of 10 cents per sub-bit. The central line indicates the starting point for open strings, while a green arrow signifies accurate pitch. If the pitch difference exceeds a sub-bit, the arrow will turn white.
• Visual Feedback: The comprehensive visual feedback system informs users whether the pitch is within an acceptable range by illuminating green or white lights. This feature allows for easy adjustments based on the displayed lighting arrows on the scale.
