IR Type: ER – Early Reflections Algorithm Control
The early reflections and filter characteristics of a room greatly determine its character.
Reverberate’s proprietary virtual point source early reflection algorithms (Hall, Room, Chamber,
Basilica, Canyon etc) can be used to supplement or compliment an impulse response’s early
reflections directly within the plug-in. The following controls are provided within the early
reflections module:
• Size: Controls the size of the model space and hence the time between reflections and the
quantity of attenuation due to air losses.
• Diffusion: Controls how individual reflections react when meeting walls and surfaces. A high
diffusion quantity creates reflections with a high degree of randomness.
• Distance: The distance between the transmitter and receiver.
• Position: The side to side offset between transmitter and receiver affecting wall proximity
and panning.
• Separation: The distance between stereo channels for both the transmitter and receiver
affecting the perceived width and phase characteristics of the early reflections.
• Depth: Sets the complexity of the reflection model. Low depths have fewer reflections.
• Room type: A pull-down menu below the Depth control to switch the room models.
Different rooms have different physical dimensions and filtering characteristics.
Once an IR has been established from a file or generated by the early reflections module it can be
modified using the following controls.
