Versa AE v2 — Audio Samples
v2 autoencoder with a compact MPD (41M→2.7M), lower discriminator LR (5×10⁻⁵), and higher feature matching weight (λ_fm=5.0). Trained from step 100K→150K on LJSpeech + LibriTTS (~944h).
| Original | 🔥 Versa AE v2 | Vocos |
|---|---|---|
Samples from LibriTTS dev-clean, resampled to 44.1kHz with torchaudio. Versa reconstructions use the step 150K checkpoint with EMA weights (Mel L1≈0.50). Vocos reference uses the pretrained Vocos checkpoint.
| Metric | v1 (step 100K, 41M MPD) | v2 (step 150K, 2.7M MPD) |
|---|---|---|
| MPD size | 41M | 2.7M |
| D loss | 2.79 | 3.2 (balanced) |
