Adds a delay audio effect to an audio bus. Emulates an echo by playing the input audio back after a period of time.
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.

- The volume ratio of the original audio. Value can range from 0 to 1.
- If [code]true[/code], feedback is enabled, repeating taps after they are played.
- Feedback delay time in milliseconds. Value can range from 0 to 1500.
- Gain for feedback, in dB. Value can range from -60 to 0.
- Low-pass filter for feedback, in Hz. Frequencies above this value are filtered out. Value can range from 1 to 16000.
- If [code]true[/code], the first tap will be enabled.
- First tap delay time in milliseconds, compared to the original audio. Value can range from 0 to 1500.
- Gain for the first tap, in dB. Value can range from -60 to 0.
- Pan position for the first tap. Negative values pan the sound to the left, positive pan to the right. Value can range from -1 to 1.
- If [code]true[/code], the second tap will be enabled.
- Second tap delay time in milliseconds, compared to the original audio. Value can range from 0 to 1500.
- Gain for the second tap, in dB. Value can range from -60 to 0.
- Pan position for the second tap. Negative values pan the sound to the left, positive pan to the right. Value can range from -1 to 1.
