Combined Filters ATrax Levels The ATrax Levels (ATX-LVL) is a so called "combined filter", a combination of two filters:
ATrax (ATX), for Alternate or Alternative Tracking, has to be seen an improvement of the VTracs (VTX), as it combines digits logically rather than by a simple adding of 5 to the digit. Since the conversions do not have to be done by hand any longer, other combinations can be done with simple tools online rather than with pencil and paper. The Levels filter is a so called "math filter". Math filters are created through calculations. This filter provides a way to determine the relative "level" (height) of each digit in relation to the others, the lowest digit of a number always being 1.
