作为实现 Tacotron 的第一步: Griffin-Lim Algorithm 算法实现。 github: Rabbit/Tacotron D. W. Griffin and J. S. Lim, “Signal estimation from modified short-time Fourier transform,” IEEE Trans. ASSP, vol.32, no.2, pp.236–243, Apr. 1984. 文中描述了从 short-time Fourier transform(STFT...
Therefore, after the general amplitude-based speech enhancement, we also designed a time-frequency simultaneously constrained Griffin-Lim algorithm (TFC-GLA) to ensure that the HB signal estimations satisfy the time-domain constraint while maintaining the estimated amplitude in frequency-domain. Objective...
Python implementation of the Griffin and Lim algorithm to recover an audio signal from a magnitude-only spectrogram. Description This is a python implementation of Griffin and Lim's algorithm to recover an audio signal given only the magnitude of its Short-Time Fourier Transform (STFT), also know...
