Projects / vibtoolbox


Vibtoolbox is a set of command line tools for the analysis of vibration and acoustic test data. The interface design used for most of the tools in the package is the standard UNIX filter model. The tools take input on standard input and transform the input in some fashion, and then send the transformed input data to standard output. The tool set also defines ASCII and native binary database formats for the storage of vibration and acoustic laboratory and flight test data.

The source file comments and info file data for the ifft and fft programs were updated. gsine was revised to use double varibles to compute sine signal. Skewness, Kurtosis, and excess Kurtosis were added to the checkth program. The usage message for the thrms program was updated.
