+Full feature list
+Signal acquisition: reads NVGate .ors / .orm files directly — no DLL, no NVGate open
+Multi-channel: up to 10+ simultaneous channels; channel labels read from NVGate recording metadata (e.g. x, y, z)
+Smallwood recursive filter: vectorised NumPy implementation; all frequencies computed in a single forward pass
+Frequency axis: 1/3, 1/6, 1/12 or 1/24 octave resolution; user-defined f_min / f_max
+SRS types: Maximax (absolute maximum), Positive, Negative
+Physical quantities: Acceleration SRS + derived Pseudo-Velocity SRS + Pseudo-Displacement SRS
+Shock zone: auto-detection + manual override (drag on plot or type Start/End in seconds)
+Residual SRS: computes SRS on the signal segment after the shock ends
+Multi-axis combination: SRSS and/or Worst-case Envelope across all loaded channels
+Pass/Fail: 30+ built-in normative curves; user CSV; scale factor (dB); multi-channel worst-case
+CSV export: full table (per-channel SRS, SRSS, limit, per-channel margin, worst margin, status)
+PNG export: Pass/Fail chart at 150 dpi
+NVGate injection: injects all SRS curves into NVGate on log-log display, autoscaled
+Preprocessing: DC offset removal, noise floor suppression
+Dark theme: optimised for lab-room screen visibility
