SeismoSpect – Signal Processing for Ground Motion Records
SeismoSpect allows users to open accelerograms from text files in different formats, to create their own library of ground motion records and save them all in a single file making it easy to handle and share large numbers of records. It features a user-friendly visual interface and is capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers.
The structure of the program follows a very straightforward methodology with a series of input modules (tabs) from the input definition to the results to be extracted. This rational and intuitive approach makes it extremely easy to learn and use; neither manuals, nor tutorial examples or videos are required.
