Are the 2-byte samples in the data blocks written in big or little endian?
Indeed, the byte order for the integer datasamples is different in (a.o.) Intel and Motorola processors. In the first EDF application, described in the original article, the Intel little endian byte order was applied (see section Results) because we had mainly PC’s in mind. That is, the lower-significance byte was stored before (at lower address than) the higher-significance byte: the integer samples were stored “little-end-first”. At present (March 1999) probably all EDF files in the world are in the little endian format and certainly all EDF viewers expect so. Let us keep it that way and ask the Motorola users to force the little endian in their routines. Some Sun users already did so in Matlab. So, EDF samples should be stored in the little endian format (the default format in PC applications).
