abstract: '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)

  a master record table.'
