Open the Tuning Panel in the toolbar to see tuning controls for all of the beams in your preset. If you want to tune beams in a specific layer, click on the layer. The contextual menu will appear in the viewport, where the Tuning Icon can be clicked.
In the Tuning Panel, you can adjust the following parameters:
Gain can only be negative and always starts from 0.0 dB. Using the arrow buttons, the Gain is decreased or increased in equal increments. The results will be reflected in the simulation in real-time if the simulation is running.
Delay can only be positive, and always starts from 0.0 ms. Using the arrow buttons, the Delay is decreased or increased in equal increments
The Delay Settings featured in the Tuning Panel allow you to adjust the delay of your system without impacting the simulation. This feature can be used to compensate for the time it takes for sound to travel from the array to the audience area. Although the Delay feature does not currently impact the simulation, it will be audible if the configuration from HOLOPLOT Plan is connected to a real-world HOLOPLOT Audio System.
Choose to view how beams perform in the simulation by selecting the AES2, M-Noise or normalized male speech in the input signal drop-down.
The input signal spectrum of AES2 has a crest factor 4 (12 dB) - band-limited pink noise from 20 Hz to 20 kHz with uncorrelated signals and no interference taken into account.
M-noise approximates the statistical characteristics of music signals, providing a realistic input for assessing the performance and behavior of audio systems.
The IEC male speech spectrum at 1/12-oct intervals is shown below. All levels are normalized to an overall SPL of 0 dB.
Both the predicted speech intelligibility and the system power headroom are highly dependent on the spectrum of the speech signal. If the input signal defined when a beam was optimized and is different to the input signal selected for that beam in the simulation, results may look different than expected.
Use the Mute button to mute any given or multiple beams. Beams can be muted individually. When a beam is muted, the results for that beam will not be calculated in the simulation.
The Mute control only applies to the simulation; beams are not muted when a project is exported to HOLOPLOT Control.
Use the Solo button to solo any given or multiple beams. Beams can be soloed individually. When a beam is soloed, only the results for that beam will be calculated in the simulation.
The Solo control only applies to the simulation, and beams will not be soloed when a project is exported to HOLOPLOT Control.
