Can I convert spectrograms generated with librosa back to audio?
Yes, it is possible to recover most of the signal and estimate the phase with e.g. Griffin-Lim Algorithm (GLA). Its “fast” implementation for Python can be found in librosa. Here’s how you can use it: import numpy as np import librosa y, sr = librosa.load(librosa.util.example_audio_file(), duration=10) S = np.abs(librosa.stft(y)) y_inv = librosa.griffinlim(S) And that’s how … Read more
