Abstract
This article presents a method of signal timescale modification using spectral analysis-resynthesis. It discusses an alternative technique for instantaneous frequency estimation, the Instantaneous Frequency Distribution (IFD). The partial tracking analysis employed in this process is explained in some detail, followed by a look into the resynthesis method. The article discusses this technique of time-stretching in comparison to the standard phase vocoder process. Performance details and specific aspects of this implementation are examined, including the C++ code for a time-stretching application.
