I am considering using HDF (Hierarchical Data Format) for the storage of samples created from a digital-to-analog converter. Since I don't really plan to share the data files that widely (one of the advantages of HDF), I am wondering if using HDF (versus "binary" or even ASCII) is overkill. Any HDF users out there? ;-) Thanks for any comments, -- Prof Kenneth H Jacker khj@cs.appstate.edu Computer Science Dept www.cs.appstate.edu/~khj Appalachian State Univ Boone, NC 28608 USA
