Echo()

Class representing an Echo effect.

An Echo effect represents more or more reflections of an original audio signal. It is similar to a Delay effect, except that echoes themselves can feed back into the audio processing loop, resulting in additional, decaying echoes.

Methods

currentParameterValues() → {Object}
effects/EffectBase.mjs, line 30

Returns the value of all effect parameters at the current time.

Returns:
Object -

Effect-specific parameter values with keys as returned by getAvailableEffectParameters()

Overrides:

getInputNode() → {AudioNode}
effects/EffectBase.mjs, line 53

Returns a reference to the AudioNode to which all source AudioNodes should be connected in order to activate this Effect.

Returns:
AudioNode -

Reference to the first AudioNode in the effect sequencing pipeline

Overrides:
See:

getOutputNode() → {AudioNode}
effects/EffectBase.mjs, line 62

Returns a reference to the AudioNode from which all effect-modified output audio is produced.

Returns:
AudioNode -

Reference to the final AudioNode in the effect sequencing pipeline

Overrides:
See:

async load()
effects/EffectBase.mjs, line 23

Loads the necessary data to implement the corresponding Effect, which can then be applied to an individual Track or to the aggregate output of all tracks.

Overrides:

async update(echoTime, intensity, opt updateTime, opt timeConstant) → {Promise.<boolean>}
effects/Echo.mjs, line 77

Updates the Echo effect according to the specified parameters at the specified time.

Note that the updateTime parameter can be omitted to immediately cause the requested changes to take effect.

Parameters:
Name Type Attributes Description
echoTime number

Number of seconds between the original audio and its first echo between [0, 1]
intensity number

Percentage of the original audio that will be present in each consecutive echo between [0, 0.95]
updateTime number <optional>

Global API time at which to update the effect
timeConstant number <optional>

Time constant defining an exponential approach to the target
Returns:
Promise.<boolean> -

Whether the effect update was successfully applied

Overrides:

static getParameters() → {Array.<EffectParameter>}
effects/Echo.mjs, line 51

Returns a list of all available parameters for manipulation in the effectOptions parameter of the update() function for this Effect.

Returns:
Array.<EffectParameter> -

List of effect-specific parameters for use in the effect's update() function
