WebMay 11, 2024 · Phase retrieval is a problem encountered not only in speech and audio processing, but in many other fields such as optics. Iterative algorithms based on non-convex set projections are effective and frequently used for retrieving the phase when only STFT magnitudes are available. While the basic Griffin-Lim algorithm and its variants … WebThis implementation is based on the (fast) Griffin-Lim method for Short-time Fourier Transforms, [2] but adapted for use with constant-Q spectrograms.
