This paper presents an extension to the dual-window-length Real-Time Iterative Spectrogram Inversion phase estimation algorithm (RTISI). Instead of a transient detection in advance, the phase estimator itself determines the correct window length when the phase information for all window lengths have already been estimated. This way, we get significant improvements compared with the previous method. Additionally, we extend this estimator to configurations with three or more window lengths.
