I am currently working on a project where I want to create an 2000ms echo of an voice input. This echo should be repeated while it looses every repetition 5% of its gain. Additionally, Echo and new input should be mixed. I hope my description explains the overall functionality of my project.
I had a look into Echo Effect example which goes in the right direction. Now I would like to refeed the echo into the input after reducing it by 5%.
