changed the definition of "direct mapping" to refer to the process of creating patent intervals- as per the clarification by Xenwolf.
Line 1: Line 1:
A '''patent interval''' in a given [[EDO]] is the number of EDO steps needed to reach the best approximation of a given interval – usually, but not necessarily just – in that EDO, and as such, it is also called a '''direct mapping'''.  It is calculated by [[rounding]] the product of the [[Wikipedia: binary logarithm|binary logarithm]] (''log2'') of the interval ratio (''r'') and the EDO number (''nEdo'').
