Audio Echo

Is it possible to add an echo effect to an audio recording on Scratch? I tried coding it to where it plays the same audio 1/10th of a second apart using two When Clicked strings, but the project refused to let the duplicate audio files play at the same time. If it's possible, how can I code an echo effect? Any tips or advice is appreciated.

Use a sound editing program to make an echo, then put it on scratch.

I have tried that, but Scratch decreases the audio quality when I import the file.

However, the way I would do it is to copy the sound file, introduce 1/10th second of silence at the beginning of the copy, then reduce the loudness.

Now just play both soundfiles at the same time. The copy is the echo.

EDIT: In fact, I just did it. Here is an echo…
