Core Effects Descriptions

Lite Reverb

Reverberation is a simulation of a natural space such as a room or hall. The Lite Reverb algorithm is designed to simulate various rooms and reverberation plates while using fewer DSP resources than the Stereo Reverb. Up to ﬁve Lite Reverbs can be used at once.

Decay time deﬁnes the time it takes for the reﬂected sound from the room to decay or die away. The diagram below shows a generalized reverberation envelope.

Early Reflections

ReverberationTime

After a short pre-delay period, the echoes from the closest walls or ceiling are heard. These ﬁrst echoes, or Early Reﬂections, vary greatly depending on the type of room. Some time after the early reﬂection cluster ends, the actual Reverberation (a dense cloud of complex wall reﬂections) begins and decays according to the time set by the Decay Time parameter. The Reverberance parameter controls the density and smearing of both the early reﬂections and the reverberation cloud.

High frequency energy tends to fade away ﬁrst as a sound is dissipated in a room. The High Frequency Decay Factor adjusts the time it takes for the high frequency energy to die away and thus changes the characteristics of the room. Rooms with smooth, hard surfaces are more reﬂective and have less high frequency damping. Rooms ﬁlled with sound absorbing materials, such as curtains or people, have more high frequency damping.

The Low Frequency Decay Factor parameter adjusts the time it takes for the low frequencies to die away. This control adjusts the “boominess” of the room.

Parameter	Description

Decay Time	Sets the reverb decay time. Range: 0% to 100%

HF Decay Factor	Sets the rate at which high frequencies die away. The high
	frequencies last longer as the percentage is increased.
	Range: 0% to 100%

LF Decay Factor	Sets the rate at which low frequencies die away. The low
	frequencies last longer as the percentage is increased.
	Range: 0% to 100%

Early Reﬂections	Sets the volume of the initial wall reﬂections.
	Range: 0% to 100%

Reverberance	Sets the amount of scattering of the early reﬂections and
	the reverberation cloud. Range: 0% to 100%
