Use this patch to add a decaying echo effect to audio in your Spark AR Studio effects.
Connect the audio source that you want to alter, for example an audio clip, microphone or other audio source.
Switches each echo on or off.
Delay of each echo in milliseconds.
The level that the source audio is fed back into the delay instances. A value of 0 will not cause any feedback. 100 will oscillate endlessly, which isn't recommended.
The volume of the source audio. Maintaining some of the original audio is important to create a mix of source audio and the echos. A value of 0 will not include any of the source audio, while 100 will be the same volume as the source audio. Values over 100 will increase the volume of the source audio signal.
The volume of the delays. There will be equal volume of wet and dry signal if both values are set to the same number. Values over 100 will make the delays louder than the source audio.
Removes the sound effect from the audio source.
Connect to a speaker, an audio effect or another patch that has an audio input.
This example adds a sense of space or depth to sound detected by the microphone.
In the Patch Editor, a patch representing the Microphone scene object is connected to the Audio port in the Audio Delay patch. The output of the Audio Delay patch is then connected to the input of a patch representing the Audio property of a speaker:
To add a delay to the sound detected by the microphone, we changed:
Changing the Time 1 value to different milliseconds will changes the amount of time between the initial sound and the repeated sound that follows.
Setting the delay time to 100 will mean there's 100ms of time between the first sound and the repeated sound after that. A very short delay time, for example between 50 and 80, will have a slap-back style sound with very quick repeats.
Try setting Feedback to 50. This will make the delay repeats last longer, and take longer to fade away in volume.
To create rhythmic patterns, turn on Active 2, 3, and 4. Adjust the Time parameter for each. Setting the Time parameters differently for each delay section will create unique rhythmic patterns.
Editing the Feedback settings will create long, ambient delay tails.
