WebMar 3, 2024 · Audio source separation is often achieved by estimating the magnitude spectrogram of each source, and then applying a phase recovery (or spectrogram inversion) algorithm to retrieve time-domain signals. Typically, spectrogram inversion is treated as an optimization problem involving one or several terms in order to promote estimates that … WebAug 19, 2024 · 2 Answers Sorted by: 1 In general the whole complex Fourier transform is needed to reconstruct the time domain signal. However, it's possible to reconstruct a real signal it from its Fourier transform magnitude alone (or phase alone) by using some iterative techniques, or very large matrix solutions.
