Stephen D. Voran and Jaden Pieper, “Frequency-Domain Signal-to-Noise Ratios Illuminate the Effects of the Spectral Consistency Constraint and Griffin-Lim Algorithms,” Conference Paper, October 2025
The restoration of degraded audio signals is often performed on complex-valued frequency-domain (FD) representations. This requires manipulation of either magnitudes and phases or real and imaginary parts. In general, these manipulations do not prod...
