Spectral subtraction has been the backbone of real-time noise suppression for decades, and honestly it’s still the pragmatic choice for competitive play where latency is non-negotiable. The classic approach—estimating the noise floor during pauses via minimum-statistics tracking and subtracting it from each FFT bin—suffers from that telltale “musical noise” where random phase residuals create those eerie tonal blips across the spectrum. Over-subpression factors and the shift toward minimum mean-square error (MMSE) estimators using a priori/a posteriori SNR ratios mitigated this significantly, and Wiener-style
