## What is Dual Tuner?

A tuner for musical instruments with two modes: "Single" and "Multi."

[ Modes ]
Single:
Displays the note name of one string and its deviation from the target pitch on a meter. Ideal for accurately tuning one string at a time.
Pitch analysis: ACF (Autocorrelation Function)

Multi:
Displays the pitches of multiple strings and their deviations from the target pitch. Quickly check the overall tuning of your instrument.
Pitch analysis: FFT (Fast Fourier Transform)
(*) Multi mode is a supplementary feature for quickly checking the condition of multiple strings. Use the high-precision Single mode for accurate adjustment and final checks.
