5 = Bass Shelf (Uniformly boosts or attenuates all frequencies below the
<FilterFreq> levels without affecting the frequencies above. The amount of
modification is given by <FilterGain>). A Bass Shelf filter uniformly boosts
or attenuates frequencies below the specified frequency while not affecting
high frequencies above the specified frequency. For example: To increase
the gain of bass frequencies applied to a subwoofer, you can set the bass
shelf filter to uniformly increase the amplitude of all bass frequencies. The
Bass Shelf filter can also be used to uniformly decrease the bass frequencies
to eliminate a booming bass sound.

NOTE: Various combinations of these filters may be used to equalize the soundfield
in order to produce a flat response, and reproduce the sound as the recording engineer
originally intended.

The <FilterFreq> input selects the center frequency. Valid values range from 5

(5Hz) to 24000 (24kHz).
The <FilterGain> inputs boost or attenuate the center frequency, or with shelving
filters, all frequencies above or below the center frequency. Valid values range from

filters, all frequencies above or below the center frequency. Valid values range from
-360 (-36dB) to +240 (+24dB).
A <FilterGain> setting of 0 (0dB) means that the signal will pass unaffected. Values
above and below 0 will boost or attenuate the frequency in increments of .1dB. That
is, changing the filter gain value by 1 signifies a boost or attenuation of .1 decibels.
above and below 0 will boost or attenuate the frequency in increments of .1dB. That
is, changing the filter gain value by 1 signifies a boost or attenuation of .1 decibels.
The <FilterQ> input sets the width of the band of frequencies around the center
frequency, expressed in octaves. Valid values range from 0.02 to 3.5 octaves. Smaller
Q values represent a narrow band of boost or attenuation, while larger values
represent a wide band of boost or attenuation.
