The Seismic Waveform Tool (SWFT)is a code designed to do research level signal analysis on seismic waveforms, including visualization, filtering and measurement. The code allows manipulation of single or multiple traces in either interactive or batch processing modes. Along with a generalized seismic data processor, it includes tools to make standardized amplitude and coda measurements. [Download SWFT software manual (doc)]
SWFT is built on Java and works on Windows, Linux, and OS-X.
