Explanation
Sets the band interval. Larger values produce wider band intervals, and the
frequency of each band increases.
Sets the bandwidth. Larger values produce a narrower bandwidth, which
further isolates the specific frequency components that pass through the
filter.
Adjusts the volume balance between dry (the original sound) and effect sound.
Sets the range in which the filter works.
Adjusts the volume of the effect sound.
