The range will depend on the maximum distance between each two notes in the scale defined in the Lingot settings (try to provide scales with low maximum distance, i.e. with many notes, to have a higher resolution in this gauge), True Deviation True label_item 0 True 0 in True 12 110 100 True vertical True Estimated fundamental frequency in hertzs. f = --- 0 True Closest note to the estimated frequency, according to the scale defined in the Lingot settings. --- 1 True Error in cents between the estimated frequency and the closest note according to the scale defined in the Lingot settings. e = --- 2 True Tone True label_item 1 1 True 0 in 290 96 True True automatic automatic True queue True This area shows the spectral power density of the captured signal. The fundamental frequency is shown with a red dot, and the noise threshold with a horizontal dotted yellow line. If you have a large FFT buffer (with more than 512 samples), you can browse through the whole spectrum with a horizontal scrollbar. True Spectrum True label_item 2
