Enumerations

enum FilterDB: 🔗

FilterDB FILTER_6DB = 0

Cutting off at 6dB per octave.

FilterDB FILTER_12DB = 1

Property Descriptions

float cutoff_hz = 2000.0 🔗

• void set_cutoff\ (\ value: float\ )
• float get_cutoff\ (\ )

Threshold frequency for the filter, in Hz.

---

FilterDB db = 0 🔗

• void set_db\ (\ value: FilterDB\ )
• FilterDB get_db\ (\ )

Steepness of the cutoff curve in dB per octave, also known as the order of the filter. Higher orders have a more aggressive cutoff.

---

float gain = 1.0 🔗

• void set_gain\ (\ value: float\ )
• float get_gain\ (\ )

Gain amount of the frequencies after the filter.

---

float resonance = 0.5 🔗

• void set_resonance\ (\ value: float\ )
• float get_resonance\ (\ )

Amount of boost in the frequency range near the cutoff frequency.
