Memory-mapped file storage

Large acoustic models can require substantial amounts of RAM to store calculated sound levels. In previous versions, all level data was held in memory, which limited model size to available RAM.

From v3.0.15, dBSea uses memory-mapped files to back these large data arrays. The operating system manages the data on disk and pages portions into RAM as needed. This means the practical limit for model size shifts from available RAM to available disk space — allowing significantly larger models to run on machines with modest memory.

See the FAQ for more detail.

XYZ levels export

Sound level results can now be exported in XYZ format, providing a simple comma-separated output of coordinates and levels suitable for import into GIS software or further analysis.
