 It is unlikely that one bit samples would ever occur as they can only represent the values {0, 1}, {-1, 0} or {-1, 1}, all of which are not particularly useful for encoding songs — if they were to occur then it is unclear which of the three possibilities is the correct interpretation.This section walks through decoding ADX 'version 3' or 'version 4' when "Encoding Type" is "Standard ADX" (0x03).An encoder can also be built by simply flipping the code to run in reverse.
