The Band Extrapolation enhancement allows certain frequencies to be emphasized or suppressed.     
The following sliders are available in the Spectral Remixer area:
High Frequency
Indicates the intensity of the high frequency.
Dry Signal
Indicates the intensity of the original signal.
Low Frequency
Indicates the intensity of the low frequency.
The following sliders are available in the Filter area:
High Frequency
Indicates the frequency above which high frequencies are to be amplified.
Low Frequency
Indicates the frequency below which low frequencies are to be amplified.
 
Frequency
The frequency denotes the oscillations per second of an electrical or magnetic field. With audio files this means that the frequency increases with rising pitch. The unit is Hertz (Hz). The highest magnitude of oscillation is called the amplitude.
