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 scripts\mulac.sts) 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
