param

param(params): boolean
This method gets or sets parameters for preamp effector. This method is overloaded for type interface and type check.
Parameters
- params: "state"
  This argument is string if getter. Otherwise, setter.
Returns boolean
Return value is parameter for preamp effector if getter. Otherwise, return value is for method chain.

params

params(): Required<PreampParams>
Returns Required<PreampParams>
Overrides Effector.params
- Defined in SoundModule/Effectors/Preamp.ts:695

start

start(startTime?): void
This method starts LFO. Namely, this method starts effector.
Parameters
- Optional startTime: number
  This argument is in order to schedule parameter.
Returns void
Inherited from Effector.start
- Defined in SoundModule/Effectors/Effector.ts:44

state

state(): boolean
This method gets effector state. If returns true, effector is active.

Returns boolean
Inherited from Effector.state
- Defined in SoundModule/Effectors/Effector.ts:107

stop

stop(stopTime?, releaseTime?): void
This method stops LFO, then creates instance of OscillatorNode again.
Parameters
- Optional stopTime: number
  This argument is in order to schedule parameter.
- Optional releaseTime: number
  This argument is in order to schedule parameter when it is necessary to consider release time.
Returns void
Inherited from Effector.stop
- Defined in SoundModule/Effectors/Effector.ts:58

toJSON

toJSON(): string
This method gets effector's parameters as JSON.

Returns string
Inherited from Effector.toJSON
- Defined in SoundModule/Effectors/Effector.ts:99

`Static` createCurve

createCurve(level, numberOfSamples): null | Float32Array
This class (static) method creates instance of Float32Array for WaveShaperNode.
Parameters
- level: number
  This argument is preamp effect level.
- numberOfSamples: number
  This argument is curve size.
Returns null | Float32Array
Return value is WaveShaperNode's 'curve'.
