Introduction and Overview

Short-Time Fourier Transform (STFT) techniques [1,3,2,5,17,18,19] are widely used in computer music applications [6,13] for analysis-based additive synthesis. With these techniques, the signal is modeled as a sum of sine waves, and the parameters to be determined by analysis are the slowly time-varying amplitude and frequency for each sine wave.

In the following subsections, we will review the short-time Fourier transform, the phase vocoder, additive synthesis, and overlap-add synthesis. We then close the introduction with an outline of the remainder of the paper.
