%description
Implements short-time Fourier transform (STFT) based processing of
strong-motion time series: time-grid regularisation, STFT-window and
anti-alias-resampling strategy selection, edge tapering, and
frequency-domain integration and differentiation, mapping a single input
(acceleration, velocity, or displacement) to a consistent triplet under a
chosen analysis bandwidth. Also provides intrinsic-mode-function
decomposition via empirical mode decomposition (EMD), ensemble EMD (EEMD),
and variational mode decomposition (VMD) with optional band-rule
filtering; elastic single-degree-of-freedom (SDOF) response spectra
(pseudo-spectral acceleration, velocity, and displacement) by exact
state-space integration; intensity measures including peak,
root-mean-square (RMS), Arias intensity, significant-duration, cumulative
absolute velocity, mean period, and the derived indices earthquake
destructiveness potential (EPI) and power-of-input (PDI); and D50 and D100
horizontal response spectra. Methods: Huang et al. (1998)

<doi:10.1109/TSP.2013.2288675>, Boore (2010) <doi:10.1785/0120090179>. An
optional indexing layer parses provider files in formats including 'PEER'
'NGA-West2' 'AT2', 'CESMD' 'V2'/'V2c', 'NWZ' 'V2A', Geological Survey of
Canada 'TR', 'IGP'/'UCR' 'AC' variants, and generic two-column ASCII text,
normalises components, writes per-record CSV (comma-separated values) and
JSON (JavaScript Object Notation) pairs, and assembles a master record
table.
