## Syntax

```lua
bool setSoundEffectParameter(sound|player target, string effect, string param, float|bool value)
```

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `target` | `sound\|player` | A `sound`, a `dui`, or a player to change their voice in voice chat. |
| `effect` | `string` | The effect's name: `chorus`, `compressor`, `distortion`, `echo`, `flanger`, `gargle`, `i3dl2reverb`, `parameq`, `reverb` or `radio`. |
| `param` | `string` | The name of the effect's parameter (see the list below). |
| `value` | `float\|bool` | The new value, within the parameter's range. `panDelay` takes a boolean; integer parameters are truncated. |

## Returns

`true` if the value was applied, `false` if the target was not found.

## Example

```lua
local music = playSound("sounds/track.mp3", true)
setSoundEffectEnabled(music, "echo", true)
setSoundEffectParameter(music, "echo", "feedback", 30)
setSoundEffectParameter(music, "echo", "panDelay", true)
```

### Note

Raises an error if the effect is not on, the parameter does not exist or the value is out of range.
