# rvc-model

The model files used by [rvc-next](https://github.com/licyk/rvc-next-dev), a rewrite of
Retrieval-based-Voice-Conversion-WebUI (RVC), organised by category, together with the official
RVC demo voices.

Everything here is copied unchanged from the official RVC repository,
[lj1995/VoiceConversionWebUI](https://huggingface.co/lj1995/VoiceConversionWebUI) (revision
`e6d0c1a`), except the FCPE and CREPE pitch models, copied unchanged from the
[torchfcpe](https://github.com/CNChTu/FCPE) 0.0.4 and [torchcrepe](https://github.com/maxrmorrison/torchcrepe)
0.0.24 packages, which bundle them. The demo voices come
from inside RVC's distribution packages (`RVC*.7z`), where they are the only copies.
`manifest.json` lists every file with its size, SHA-256 and where it came from.

## Contents

| Folder | Files | Used for | Upstream path |
| --- | --- | --- | --- |
| `hubert/hubert_base/` | `config.json`, `preprocessor_config.json`, `pytorch_model.bin` | Content features (HuBERT/ContentVec), for conversion and training | `hubert_base/` |
| `rmvpe/` | `rmvpe.pt`, `rmvpe.onnx` | Pitch extraction (RMVPE); the ONNX export for DirectML | `rmvpe.pt`, `rmvpe.onnx` |
| `fcpe/` | `fcpe_c_v001.pt`, `LICENSE-FCPE.txt` | Pitch extraction (FCPE) | `torchfcpe/assets/fcpe_c_v001.pt` in torchfcpe 0.0.4 |
| `crepe/` | `full.pth`, `tiny.pth`, `LICENSE-CREPE.txt` | Pitch extraction (CREPE full and tiny) | `torchcrepe/assets/` in torchcrepe 0.0.24 |
| `pretrained/v1/` | `{f0,}{G,D}{32k,40k,48k}.pth` | Base models for training v1 voices, with (`f0`) and without pitch guidance | `pretrained/` |
| `pretrained/v2/` | the same twelve files | Base models for training v2 voices | `pretrained_v2/` |
| `separation/` | five BS-/Mel-Roformer checkpoints and their YAML | Vocal separation, dereverb and karaoke (PyMSS) | `pymss_weights/` |
| `voices/<name>/` | `<name>.pth`, `<name>.index` | The official demo voices | inside the `RVC*.7z` packages |

## Demo voices

| Voice | Version | Rate | Pitch guidance | Index |
| --- | --- | --- | --- | --- |
| `kikiV1` | v1 | 40k | yes | yes |
| `keruanV1` | v1 | 40k | yes | yes |
| `guanguanV1` | v1 | 40k | yes | yes |
| `zhanzhanv2-xi` | v2 | 40k | yes | yes |
| `youzhanv2-xi` | v2 | 48k | yes | no (none was ever published) |

Each is an RVC small model (`.pth`) with its retrieval index (`.index`); they load in the original
RVC WebUI as well as in rvc-next (`rvc-next model download --all`, or **Models › Voices › Demo
voices**).

## Licence

MIT, as the upstream repository, including its authors' condition (in `LICENSE-RVC.txt`): the
software is for research use only, and users bear full responsibility for the voices they produce
and distribute; anyone who does not accept this may not use these files. The licences of the
components the models build on (ContentVec, VITS, HiFi-GAN, UVR, audio-slicer) are listed in the
same file.

The FCPE model (`fcpe/`) is not part of RVC: it is MIT-licensed by its authors (Copyright (c) 2023
CN_ChiTu), without the research-use clause; its licence is `fcpe/LICENSE-FCPE.txt`. The CREPE
models (`crepe/`) are not part of RVC either: MIT-licensed by torchcrepe's author (Copyright (c) 2020
Max Morrison) and converted from CREPE (Copyright (c) 2018 Jong Wook Kim), without the research-use
clause; see `crepe/LICENSE-CREPE.txt`.
