I took the song Truce by Twenty One Pilots and used a delay with feedback. The delay is 0.75s long, and each time it repeats the volume is multiplied by 0.65 and the sampling rate is lowered to 0.4Hz. The resulting effect was similar to an echo. I choose the song Truce because it’s a slower song and I thought it would sound nice with an echo.
