class FMOD::Effects::ITLowPass
This unit filters sound using a resonant low-pass filter algorithm that is used in Impulse Tracker, but with limited cutoff range (0 to 8060hz).
This is different to the default {LowPass} filter in that it uses a different quality algorithm and is the filter used to produce the correct sounding playback in .IT files.
FMOD
Studio's .IT playback uses this filter.
@note This filter actually has a limited cutoff frequency below the
specified maximum, due to its limited design, so for a more open range filter use {LowPass} or if you don't mind not having resonance, {LowPassSimple}. The effective maximum cutoff is about 8060hz.
@attr cutoff [Float] Low-pass cutoff frequency in Hz.

@attr resonance [Float] Low-pass resonance Q value.
