AudioParam

The Web Audio API's AudioParam interface represents an audio-related parameter, usually a parameter of an AudioNode (such as GainNode.gain).

interface AudioParam {
automationRate: AutomationRate;
readonly defaultValue: number;
readonly maxValue: number;
readonly minValue: number;
value: number;
cancelAndHoldAtTime(cancelTime: number): AudioParam;
cancelScheduledValues(cancelTime: number): AudioParam;
exponentialRampToValueAtTime(value: number, endTime: number): AudioParam;
linearRampToValueAtTime(value: number, endTime: number): AudioParam;
setTargetAtTime(
target: number,
startTime: number,
timeConstant: number,
): AudioParam;
setValueAtTime(value: number, startTime: number): AudioParam;
setValueCurveAtTime(
values: number[] | Float32Array,
startTime: number,
duration: number,
): AudioParam;
setValueCurveAtTime(
values: Iterable<number>,
startTime: number,
duration: number,
): AudioParam;
}
var AudioParam: {
prototype: AudioParam;
new (): AudioParam;
};
