With the most resent release of BIOSIG (Version 1.51), support for
several file formats has been added. Now, more than 30 formats for
biosignal and several others (acustic and image formats) and are
supported. This is more than any other biosignal processing package - at
least what I'm aware off.
The status of supported formats is available at
