Pre Delay: Sets the delay time (in ms) between the input signal and the start of the reverb.

Size: Sets the perceived size of the reverberant space.

Decay: Sets the time or length of the reverb tail.

Damp: Low Pass filter that dampens the higher frequencies of the reverb.

Band Width: Space between initial reverb reflections. Low = less space, and high = more space.

Early/Late Reflections: Sets the blend of Early/Late Reflections. Early Reflections are direct echoes of the signal, while Late Reflections are diffused and sound more “roomy.”
