Hello, I'd like to make the same or very similar echo on the vocals as in Audacity by using the Effect / Echo plugin effect. I'm looking for a daw plugin that can do the same thing as fragility and you can write a way to do it. Audacity echo setting: delay time 0.2 decay factor 0.2. thank you for answer <3

 

Any stock delay (in your DAW) will most likely do this easily.

Here are a bunch of free ones.
