AudioNoiseGateFilter

Electron APIs / recorder / AudioNoiseGateFilter

A noise gate filter used to attenuate signals that fall below a certain threshold. It is primarily used to remove background noise during silent passages.

Example

const gate: AudioNoiseGateFilter = {
  id: "noise_gate_filter",
  parameters: {
    open_threshold: -40,
    close_threshold: -45,
    hold_time: 200,
  },
};

Properties

Property	Type	Description	Overrides
id	"noise_gate_filter"	A unique identifier for the filter instance.	AudioFilterBase.id
parameters?	object	Configuration settings for the noise gate.	AudioFilterBase.parameters
parameters.attack_time?	number	The time (in ms) it takes for the gate to fully open once the signal exceeds the open threshold. Valid range: [0, 10000]	-
parameters.close_threshold?	number	The level (in dB) at which the gate closes, silencing the signal. Valid range: [-96.00, 0.00]	-
parameters.hold_time?	number	The duration (in ms) the gate remains fully open after the signal drops below the close threshold before the release phase begins. Valid range: [0, 10000]	-
parameters.open_threshold?	number	The level (in dB) at which the gate opens, allowing the signal to pass. Valid range: [-96.00, 0.00]	-
parameters.release_time?	number	The time (in ms) it takes for the gate to fully close after the hold period. Valid range: [0, 10000]	-
