classHighpassFilter

@codexo/exojs / audio / stable

High-pass filter backed by a `BiquadFilterNode` in `highpass` mode. Attenuates frequencies below the cutoff and passes everything above it. Useful for removing low-frequency rumble, thinning out bass-heavy audio, or sculpting mix headroom. The `resonance` (Q) parameter controls the sharpness of the roll-off peak at the cutoff frequency.

Methods1
destroy(): void
Disconnects all audio nodes and releases resources. Must be called when the effect is no longer needed.
Properties5
frequency: number
Cutoff frequency in Hz. Signals below this frequency are attenuated. Range 20..20000, default 1000.
inputNode: AudioNode
The node where audio enters this effect.
outputNode: AudioNode
The node where audio exits this effect.
ready: Promise<void>
Resolves when the effect is fully initialized. Defaults to immediately-resolved for sync effects.
resonance: number
Q (resonance) at the cutoff. Higher values create a sharper, resonant peak. Minimum 0.0001, default 1.
