Table 2.

Conversion of other file formats into MEF results in significant file size reduction. XLTek data employs a form of difference encoding, so results are less impressive than for DMA and EDF, which employ no compression.

Format	Size	Recording Length (sec)	Number of Channels	MEF size	Compression Ratio
DMA	7.03 Gb	395.8	40	247.6 Mb	3.44%
XLTek^*	4.71 Gb	65267.5	76	1.91 Gb	40.53%
EDF^*	1.72 Gb	28327.6	1	150.7 Mb	8.56%

Our XLTek data was sampled at 500 Hz and our XLTek and EDF data had a 16-bit dynamic range
