Purpose

Room describes an acoustic space for Render. It sets the room bounds, materials for the walls, floor and ceiling, and obstacles that block sound. Multiple Render operators can read the same scene.

Use

Place Room from the Audio view of the Voro menu, under Other. Connect scene to Render’s scene input. Set Sizex, Sizey and Sizez, then choose a Material. Override Floor, Ceiling or Walls when those surfaces need a different material.

Originx, Originy and Originz locate the center of the room. Put Emitters and the listener in the same coordinate system. A room with Sizey of 3.5 and Originy of 1.75 has its floor at y = 0.

Inputs and outputs

Room has no inputs. Its scene output carries the room description to Render.

Controls

• Sizex, Sizey and Sizez set width, height and depth. Originx, Originy and Originz set the center.
• Material sets the room material. Floor, Ceiling and Walls inherit it when set to same as room.
• Alphatrim adjusts material absorption. Scattertrim adjusts scattering.
• Rt60 sets the decay time in seconds. Rthf controls high-frequency decay relative to it.
• Autoabsorb derives reflection level and filtering from the chosen materials. Reflection and Walllp supply manual values when it is off.
• Occluders lists boxes as lox,loy,loz,hix,hiy,hiz, separated by semicolons. Transmission sets how much sound passes through those obstacles.

Notes

Room produces a description of the space. Render produces the audio. To compare room materials, keep the sources and listener fixed while switching Material, with Autoabsorb on.
