- property ShortTimeFFT.dual_win#
- Canonical dual window. - A STFT can be interpreted as the input signal being expressed as a weighted sum of modulated and time-shifted dual windows. Note that for a given window there exist many dual windows. The canonical window is the one with the minimal energy (i.e., \(L_2\) norm). - dual_winhas same length as- win, namely- m_numsamples.- If the dual window cannot be calculated a - ValueErroris raised. This attribute is read only and calculated lazily.- See also - dual_win
- Canonical dual window. 
- m_num
- Number of samples in window - win.
- win
- Window function as real- or complex-valued 1d array. 
- ShortTimeFFT
- Class this property belongs to.
