Griffin Lim Algorithm

The Griffin-Lim algorithm (GLA) is an iterative method for phase retrieval from short-time Fourier transform (STFT) magnitude spectrograms, crucial for reconstructing audio signals from incomplete data. Current research focuses on improving GLA's performance and efficiency, exploring modifications like incorporating it into diffusion models for waveform generation and developing online, frame-by-frame versions for real-time applications. These advancements aim to enhance the quality and speed of audio reconstruction, impacting fields such as speech synthesis and audio processing by enabling higher-fidelity audio generation and more efficient real-time signal processing.
