AudioEffectDelay

Inherits: AudioEffect < Resource < RefCounted < Object

Adds a delay audio effect to an audio bus.

Emulates an echo by playing the input audio back after a period of time.

Description

A "delay" effect plays the input audio signal back after a period of time. Each repetition is called a "delay tap" or simply "tap". Delay taps may be played back multiple times to create the sound of a repeating, decaying echo. Delay effects range from a subtle echo to a pronounced blending of previous sounds with new sounds.

See also AudioEffectReverb for a blurry, continuous echo.

Property Descriptions

float dry = 1.0 🔗

• void set_dry(value: float)

• float get_dry()

The volume ratio of the original audio. Value can range from 0 to 1.

---

bool feedback_active = false 🔗

• void set_feedback_active(value: bool)

• bool is_feedback_active()

If true, feedback is enabled, repeating taps after they are played.

---

float feedback_delay_ms = 340.0 🔗

• void set_feedback_delay_ms(value: float)

• float get_feedback_delay_ms()

Feedback delay time in milliseconds. Value can range from 0 to 1500.

---

float feedback_level_db = -6.0 🔗

• void set_feedback_level_db(value: float)

• float get_feedback_level_db()

If true, the first tap will be enabled.

---

float tap1_delay_ms = 250.0 🔗

• void set_tap1_delay_ms(value: float)
