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. Output percent of original sound. At 0, only delayed sounds are output. Value can range from 0 to 1. Default value: [code]1[/code]. If [code]true[/code], feedback is enabled. Default value: [code]false[/code]. Feedback delay time in milliseconds. Default value: [code]340[/code]. Sound level for [code]tap1[/code]. Default value: [code]-6 dB[/code]. Low-pass filter for feedback, in Hz. Frequencies below this value are filtered out of the source signal. Default value: [code]16000[/code]. If [code]true[/code], [code]tap1[/code] will be enabled. Default value: [code]true[/code].
