The preferences window provides more customization options compared to the quick settings panel.

General Settings

The general settings allow modification of the simulation as well as rendering behavior.

Simulation

The Delta L (m) slider sets the distance between pixels on a real-world scale. Smaller distances correspond to a smaller area.

The Show absorbing boundary toggle displays the absorbing boundary around the simulation area. The absorbing boundary is used for more accurate free field simulations. The absorbing boundary width is modified with the Boundary width (px) slider. Greater values correspond to better free field simulations (the free field works best for wavelengths shorter than the boundary width).

Rendering

The Colormap drop-down list allows the selection of multiple different gradients for rendering. The most common scientific gradients are represented.

The Min Gradient and Max Gradient values set the minimum and maximum pressure values. Greater and smaller values are clipped at the gradient's edges.

Experimental Settings

Experimental settings offer toggles for experimental features, which are disabled / hidden by default. These features might be incomplete, broken or subject to change in the future.

The Frequency analyzer toggle enables the use of the frequency plot. There is a known bug in the analysis of white noise or Gaussian sources post-diffraction, characterized by the emergence of unexplainable high-frequency components.

The Mic values export toggle adds an Export CSV button to each microphone entry in the outline panel. This button exports all recorded pressure values into a .csv file. The export is done in the background and the file is saved in the current working directory.

The Wave files toggle loads a .wav file and sets the delta l value to the corresponding sample rate. Each source now supports the Wave file waveform. Selecting this waveform type makes the source use the loaded wave file as an input. The simulation time controls the playback time of the audio file. A new Export wav button is also added to each microphone entry in the outline panel. This button exports all recorded pressure values into a wave file.
