sample2ps tools

The sample2ps tools are three programs which draw graphic representations of samples. See the sample pictures below for examples. Output of all programs is Encapsulated PostScript (eps) which gives perfect results for usage in printed documents.

The software should compile cleanly on unix systems where the FFTW and libsndfile libraries are available.
