wconvert

Compute the normalized, dual and tight version of a window function. This function is used in the analysis- and synthesis-part of frame multiplier implementations (e.g.: the script application MulAc) to support perfect signal reconstruction.

Usage

wconvert(x, 0)	... normalized window
wconvert(x, 1, m)	... dual window
wconvert(x, 2, m)	... tight window

x

a vector containing the window function to be converted

m

the hopsize used for analysis and synthesis in samples; 1 ≤ m ≤ ncol(x)

Result

a vector with same length as x containing the converted window function
