FAQ & Troubleshooting
Noise Gate and Threshold
   
Threshold slider is placed at the right of Spectrum window. It defines the lowest sound level the program will analyze. All sounds below this level, both noise and notes, will be ignored. This level is depicted in Spectrum window by yellow dotted line moving synchronously with slider.

Noise Gate control sets up norm value for spectrum. If Noise Gate value is lower than Spectrum window peak, spectrum is normalized to the peak, otherwise spectrum is normalized to Noise Gate value.

Please note that dotted line is visible only when "Wave In" is turned on. When choosing Mono Correlator detection algorithm, Threshold control is inactive.
