The shock response spectrum (SRS) allows to estimate transient acceleration signals in terms of a maximum response of a dynamic vibration system. Its origin probably dates from civil engineering and the problem of seismic excitations, i.e. earthquake response of buildings, see Clough Penzien 1975. The SRS is a spectrum, i.e. a curve giving the maximum acceleration response depending on frequency. It is derived from a 1-mass-spring-damper vibration system being excited by a base excitation, i.e...

Eiger is an electromagnetic software for frequency domain analysis. It consists of physics models for 2D and 3D electromagnetic scattering, radiation, and penetration problems. It contains Green's functions for periodic and layer medium.

Sculptor is a phase-vocoder-based package with real-time capabilites. You can use it to fiddle with soundfiles in the frequency domain, changing pitch and duration independently.
