Other EDF software

Some commandline format converters (without graphical user interface) for scripts or batchfiles.
Note that these converters are also in EDFbrowser.

A very convenient open-source programming library for C/C++ programmers who want to implement EDF(+) and/or BDF(+).

EDF for Labview, a collection of VI's to write files in the European Data Format.
