Parametric Equalizer Filter

Discussion

This filter allows you to select a frequency range and boost or cut the signal in that range. The boost or cut amount is smoothly ramped down in either direction in a bell curve.

Name for use with AIL_find_filter: "Parametric EQ Filter"

Properties:

"ParmEQ Center": Center Frequency. Range: 20.0 Hz to Nyquist (one-half the driver's output sample rate in Hz).

"ParmEQ Q": Width in octaves of band. Range: 0.01 to 1.0.

"ParmEQ Gain": Boost / Cut amount. Range: -18.0 to 18.0 dB.

"Mix": Wet/dry mix. Range: 0.0 (no effect) to 1.0 (full effect).

When a mix value of 0.0 is specified, the filter will operate on an internal "fast path" designed to consume minimal CPU resources.
