The DelayNode collects audio data from all of its inputs and applies a delay filter before passing it off to its outputs.
Common Uses
- Using the
FeedbackPercentproperty to create echo effects - Combining with other audio filters to create sound effects
Using the DelayNode
The delay filter plays a second copy of the audio which is delayed by the number of seconds set by the Delay parameter. The FeedbackPercent property sets a percentage of the filter output which is fed back into the filter as input. If the FeedbackPercent is 0, the user will only hear one repeat of the sound. If it was 100, the sound would keep repeating indefinitely. Values in between will make each echo quieter than the last.
The WetPercent property controls the loudness of the delayed echo. At 100 the echo will sound just as loud as the original sound. Lower values will make the echo quieter than the sound.
