Line 1: '''Reassignment methods''' take a [[time-frequency representation]] (TFR) and move each discrete contribution to the frequency given by its rate of change of phase. As the rate of change of phase in a TFR is more concentrated, reassignment results in a much sharper representation. ==description== A new, improved implementation of STFT has recently been devised by Fitz et al., and has found numerous applications in speech signal processing and signal roughness analysis (e.g. Vassilakis and Fitz, 2007). The algorithm, based on reassigned bandwidth-enhanced modeling (Fitz & Haken, 2002; Fitz et al., 2003; Fulop & Fitz, 2006a,b, 2007) incorporates an automatic spectral peak-picking process to determine which frequency analysis bands correspond to spectral components of the analyzed signal.
