--- license: mit tags: - audio - speech - autoencoder --- # 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 v2Vocos
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) |
