Balance of the dry sound and effect sound
Reverb length
Spread of the reverb
Delay time until the early reflections
Frequency at which the high pass filter will cut the low range
Frequency at which the low pass filter will cut the high range
Width of the simulated room
Height of the simulated room
Depth of the simulated room
Wall surface of the simulated room (higher values produce more random reflections)
Delay time from the early reflections until the reverberation
Density of the reverberation
Level balance of the early reflections and the reverberation
High range attenuation (lower values cause the high range to decay faster)
Amount of feedback for the initial delay
