The Spectral Noise Reduction algorithm uses three notch filter banks to remove tonal disturbances from audio signals. It can help eliminate noises from original footage, such as buzz and whistling tones.

Freq (1-3)

Determines the center frequency of each of the notch filters.

Red (1-3)

Sets the input gain level at which the color red appears in the meter for a given track.

On (1-3)

Activates the corresponding filter bank.

MaxLevel

Determines the gain reduction of each notch filter, thus controlling the amount of noise removed from the signal.

CursorMode

Activates the adjustment of the filter frequency by the cursor.
