Adds a delay audio effect to an audio bus. Plays input signal back after a period of time. Two tap delay and feedback options. Plays input signal back after a period of time. The delayed signal may be played back multiple times to create the sound of a repeating, decaying echo. Delay effects range from a subtle echo effect to a pronounced blending of previous sounds with new sounds. $DOCS_URL/tutorials/audio/audio_buses.html Output percent of original sound. At 0, only delayed sounds are output. Value can range from 0 to 1. If [code]true[/code], feedback is enabled. Feedback delay time in milliseconds. Sound level for feedback. Low-pass filter for feedback, in Hz. Frequencies below this value are filtered out of the source signal. If [code]true[/code], the first tap will be enabled. First tap delay time in milliseconds. Sound level for the first tap. Pan position for the first tap. Value can range from -1 (fully left) to 1 (fully right). If [code]true[/code], the second tap will be enabled. Second tap delay time in milliseconds. Sound level for the second tap. Pan position for the second tap. Value can range from -1 (fully left) to 1 (fully right).
