EEG decompression challenge

Hi,

I do have some EEG data in a proprietary format, using some
undocumented/unknown compression method. The company has not disclosed
the specification. Is anybody able to write a decoder for this data?

Example data is available at
http://bci.tugraz.at/~schloegl/biosig/decode_challenge/

My guess is, it is using a delta or a prediction encoding combined with
huffman. For some files, the correct output values (obtained by some
binary software) are included in the *.asc files.
