# Simulation

Simulating in HOLOPLOT Plan is a powerful way to understand the performance and expected results of your HOLOPLOT Audio Systems. HOLOPLOT Plan’s powerful Simulation Engine enables you to simultaneously simulate and visualize system performance of a configured system in real-time, so you can make adjustments to your design and see the results immediately.

### How to simulate

You can start and stop the Simulation Engine by choosing SPL or Delay Spread in the simulation mode selector in the toolbar. 

The Simulation Engine is a computationally intensive process, so please keep this in mind when waiting for results to simulate. While the simulation is running, the zones will appear grey.
