Class Echo

java.lang.Object

de.pottgames.tuningfork.SoundEffectData

de.pottgames.tuningfork.Echo

public class Echo
extends SoundEffectData

The echo effect generates discrete, delayed instances of the input signal. The amount of delay and feedback is controllable. The delay is ‘two tap’ – you can control the interaction between two separate instances of echoes.

Field Summary

Fields

Modifier and Type	Field	Description
float	damping	Range: 0.0 - 0.99, Default: 0.5 This property controls the amount of high frequency damping applied to each echo.
float	delay	Range: 0.0 - 0.207, Default: 0.1 This property controls the delay between the original sound and the first ‘tap’, or echo instance.
float	feedback	Range: 0.0 - 1.0, Default: 0.5 This property controls the amount of feedback the output signal fed back into the input.
float	lrDelay	Range: 0.0 - 0.404, Default: 0.1 This property controls the delay between the first ‘tap’ and the second ‘tap’.
float	spread	Range: -1.0 - 1.0, Default: -1.0 This property controls how hard panned the individual echoes are.

Field Details

delay

public float delay

Range: 0.0 - 0.207, Default: 0.1
This property controls the delay between the original sound and the first ‘tap’, or echo instance. Subsequently, the value for Echo Delay is used to determine the time delay between each ‘second tap’ and the next ‘first tap’.

lrDelay

public float lrDelay

Range: 0.0 - 0.404, Default: 0.1
This property controls the delay between the first ‘tap’ and the second ‘tap’. Subsequently, the value for Echo LR Delay is used to determine the time delay between each ‘first tap’ and the next ‘second tap’.

damping

public float damping

Range: 0.0 - 0.99, Default: 0.5
This property controls the amount of high frequency damping applied to each echo. As the sound is subsequently fed back for further echoes, damping results in an echo which progressively gets softer in tone as well as intensity.

feedback

public float feedback

Range: 0.0 - 1.0, Default: 0.5
This property controls the amount of feedback the output signal fed back into the input. Use this parameter to create “cascading” echoes. At full magnitude, the identical sample will repeat endlessly. Below full magnitude, the sample will repeat and fade.

spread

public float spread

Range: -1.0 - 1.0, Default: -1.0
This property controls how hard panned the individual echoes are. With a value of 1.0, the first ‘tap’ will be panned hard left, and the second tap hard right. A value of –1.0 gives the opposite result. Settings nearer to 0.0 result in less emphasized panning.
