Spectrum Mode

Spectrum Mode enables deeper statistical analysis of your virtual sound system in HOLOPLOT Plan. To enable Spectrum Mode, open the Spectrum Panel from the toolbar. The Spectrum Panel will appear and the cursor will turn into a crosshair, indicating that you can now place acoustic probes.

Activating the Spectrum Mode

Placing probes

You can place acoustic probes on a zone’s surface by clicking on the surface. A probe dot will appear on the zone, and an info box will pop up with the probe’s X,Y, and Z location when hovered, with SPL data relevant to the bandwidth mode you are using. You can pin a probe with the button and delete a probe with the button.

Placing a Probe

Using the Spectrum Window

Your probes also appear in the Spectrum Window. All of your probes are listed on the right side of the Spectrum Window with broadband SPL values and buttons to pin or delete probes quickly. Hovering over the probe’s name will highlight both the corresponding frequency response graph to the right and will highlight the probe in the Viewport.

Using the Spectrum Window

The Spectrum Window displays the frequency response in 1/12-octave band resolution regardless of the selected simulation controls. This graph helps you identify any areas where the signal needs to be adjusted to achieve a balanced frequency response. Additionally, you can compare the frequency response of multiple probe locations, helping you compare the coverage of different areas of the audience. This feature can help you optimize your system's coverage, ensuring that your audience has the best possible listening experience.
