Adds a band-limit filter to an audio bus.
A "band-limit" filter attenuates the frequencies at [member AudioEffectFilter.cutoff_hz], and allows frequencies outside the frequency threshold to pass unchanged. It is a wider and weaker version of [AudioEffectNotchFilter], and is the opposite of [AudioEffectBandPassFilter]. This filter can be used to give more room for other sounds to play at that frequency.
