We have several updates:
1) We have successfully moved to a new server and expect more stable data loading speeds for all users.
2) We have added a new leaderboard for guitar models (includes electric and acoustic): https://mvsep.com/quality_checker/leaderboard/guitar/?sort=guitar
3) We have updated our old guitar model "MVSep Guitar (guitar, other)". Previously, it used the MDX23C architecture. Now there are two versions available: the updated version of MDX23C and MelRoformer. A comparison of quality metrics on the new leaderboard is below:
| Algorithm name | Validation type | |||
| guitar (SDR) | other (SDR) | |||
| Demucs4HT (6 stems) | 5.22 | 12.19 | ||
| mdx23c Old (2023.08, SDR: 4.78) | 4.78 | 11.75 | ||
| mdx23c New (2024.06, SDR: 6.34) | 6.34 | 13.31 | ||
| MelRoformer (2024.06, SDR: 7.02) | 7.02 | 13.99 | ||
| Ensemble (mdx23 + MelRoformer, SDR: 7.18) | 7.18 | 14.15 | ||
4) We have added a new model “MVSep Multichannel BS (vocals, instrumental)”. This model is specially prepared for extracting vocals from multi-channel audio (5.1, 7.1, etc.). After processing, it returns multi-channel audio in the same format in which it was sent to the server with the same sample rate. We accept multichannel WAV/FLAC as input.
