Description

AXART_LPF is a data structure used to describe a low pass filter sound articulator. This articulator sets the low pass filter roll-off frequency for an AXART_SOUND. Prior to calling the AXARTAddArticulator function, the user application must call the AXARTInitArtLpf function for the AXART_LPF.
