MOS score recovery.
Recovery = 100 × (denoised MOS − noisy MOS) / (reference MOS − noisy MOS). Scores are predicted by Microsoft DNSMOS P.835, not human ratings. Negative recovery means degradation; above 100% means a score above the reference. A clean–noisy gap below 0.1 is marked n/a. Summary percentages use cohort mean scores, not the mean of clip percentages.

The remaining test pairs, ordered by Super Sonique MOS recovery. The noisy listening baseline is a KVAE reconstruction, as in the previous site; both denoisers receive the original noisy waveform. MOS is calculated on the public MP3s.
Artificial noise · +5 dB
Ten held-out regular clean speech clips, mixed with recorded noise using the Sidon augmentation pipeline. Noise comes from the training noise bank: this tests held-out speech under a matched noise distribution, not unseen noise. No reverb, bandwidth, codec, clipping augmentation or packet loss is enabled. The mixer’s final saturation still applies; +5 dB is measured before saturation.
The noisy player is the actual corrupted input. Following the evaluation guide, MOS uses pre-playback float WAVs for this section. Expand codec diagnostics to hear noisy and clean KVAE reconstructions. Best Super Sonique MOS recovery first.
