Use a desktop or notebook computer to edit this space.
You can review the sample or an opened project in 2D and 3D on this device. Precise wall, corner, and column editing is available on a desktop or notebook computer.
NEW SPACE
Choose the closest floor plan.
You can change every wall and corner after the space is created.
V250 ENGINE INPUT
Acoustic model check
The planner converts this project into a calculation-ready model. This check validates the data before the separate sound analyses run.
V251 DIRECT SOUND
Direct sound analysis
Review the direct path from each speaker to one listening or measurement position.
V282.9 EARLY REFLECTIONS
First reflection analysis
Review valid first reflection paths from room surfaces and the exposed faces of large furniture. Paths blocked by furniture are removed.
V283 ROOM DECAY
Estimated reverberation time
Review the estimated sound decay in six frequency bands from the current room shape, materials, and acoustic treatment.
V286.1 ROOM MODES
Low-frequency room modes
Rectangular rooms use exact three-dimensional rigid-boundary mode frequencies. Other room shapes use the floor-plan grid with coupled height modes. The estimate also compares how the installed low-frequency treatment may reduce each mode. Start with the combined pattern, then select a frequency for diagnosis.
The estimate follows the current floor-plan boundary and retained full-height columns. It combines a two-dimensional grid wave calculation with the room's constant ceiling height.
This is an approximate prediction. Confirm critical decisions with measurements.

MY SOLAUDIOLAB PROJECTS
My SolAudioLab projects
Save named projects here to continue on another signed-in desktop or notebook computer. An .acplan file is an independent backup.
You can keep planning without an account. Sign in with Google when you want to save a named project in My SolAudioLab and open it on another device.

DIAGONAL CORNER
Make this corner diagonal.
Set where the diagonal starts on each connected wall.
COLUMN ATTACHED
Include this column in the wall shape?
The column will become part of the floor-plan boundary. One undo step restores the separate column.
WALL FRONT EDITOR
Wall Features
Place doors, windows, acoustic panels, and large curtains on the selected wall.
Drag a wall feature horizontally. Doors stay on the floor. Curtains and acoustic panels may cover other features.
QUICK START
Build the room first, then move toward analysis.
This short path keeps the acoustic model complete and makes the results easier to understand.
- 1ROOM SHAPE
Create the floor plan and set the ceiling height.
- 2MATERIALS
Set the wall, floor, ceiling, door, window, and curtain materials.
- 3OBJECTS
Add furniture, equipment, and acoustic treatment.
- 4AUDIO SETUP
Place speakers and add at least one listening or measurement position.
- 5ANALYSIS
Review direct sound, reflections, room decay, room modes, and the integrated result.
- 6VIRTUAL LISTENING
Play your own audio and hear estimated changes while you edit the room.
The sample space is read only. Select USE AS NEW PROJECT before you edit it.
Results are design estimates, not measurements. Save named projects in My SolAudioLab for other signed-in devices, keep .acplan files as independent backups, and send feedback if something does not work as expected.
