	'''SRS Tool''' is a professional [https://en.wikipedia.org/wiki/Shock_response_spectrum Shock Response Spectrum] (SRS) analysis application built for structural dynamics engineers working with OROS [[NVGate]] data acquisition systems. It reads shock recordings directly from NVGate measurement folders, computes SRS using the Smallwood (1981) recursive digital filter, and pushes results back into NVGate as live TCP result channels — all from a single application.
