In many professional measurement environments, the greatest limitation is not the instrument but the software that accompanies it. Proprietary applications often depend on specific operating systems, require continuous updates and regularly create compatibility issues as computer platforms evolve. This leads to unnecessary frustration for professionals who simply want reliable access to their data. OBSIDIAN deliberately chose a different approach by developing an open, stable and universally accessible analysis environment that removes these barriers entirely.

At the heart of this approach lies an advanced Excel based analysis and reporting framework. Excel is globally supported across virtually all operating systems and already forms part of the daily workflow of engineers, researchers, consultants and inspectors. This allows users to work with their measurement data immediately, without installations, licenses or compatibility concerns. The environment itself is far more than a spreadsheet. It is a structured analytical framework containing built in formulas, industry standards, normalization methods and graphical visualizations that automatically process and present complex spectral and temporal data in a clear and scientifically meaningful way.

Because the Excel framework is delivered as open source, users have full freedom to adapt, expand or refine formulas
