Want to understand the science behind echoes, sound reflection, and why echoes occur?

Move the distance slider to change how far the reflective surface is.
Click Shout to hear a simulated sound and its echo.
Record your voice and play it back with an echo effect.
Try the Live Echo mode to hear real-time sound reflections.
Increase the distance to observe longer echo delays.
Notice that echoes become distinct when the reflected sound arrives at least 0.1 seconds later.
