Variational Inference with adversarial learning for end-to-end Singing Voice Conversion based on VITS

中文文档

The tree bigvgan-mix-v2 has good audio quality

The tree RoFormer-HiFTNet has fast infer speed

No More Upgrade

This project targets deep learning beginners, basic knowledge of Python and PyTorch are the prerequisites for this project;
This project aims to help deep learning beginners get rid of boring pure theoretical learning, and master the basic knowledge of deep learning by combining it with practices;
This project does not support real-time voice converting; (need to replace whisper if real-time voice converting is what you are looking for)
This project will not develop one-click packages for other purposes;

A minimum VRAM requirement of 6GB for training
Support for multiple speakers
Create unique speakers through speaker mixing
It can even convert voices with light accompaniment
You can edit F0 using Excel

If you chose LargeV2, use svc_inferencermvpev2 or svc_inferencevcrepev2

If you chose LargeV3, use svc_inferencermvpev3 or svc_inferencevcrepev3

Dataset preparation

Necessary pre-processing:

Separate voice and accompaniment with UVR (skip if no accompaniment)
Cut audio input to shorter length with slicer, whisper takes input less than 30 seconds.
Manually check generated audio input, remove inputs shorter than 2 seconds or with obivous noise.
Adjust loudness if necessary, recommend Adobe Audiiton.
Put the dataset into the dataset_raw directory following the structure below.

dataset_raw
├───speaker0
│   ├───000001.wav
│   ├───...
│   └───000xxx.wav
└───speaker1
    ├───000001.wav
    ├───...
    └───000xxx.wav

Data preprocessing

By default, largeV2 is used for PPG analysis

However, you can also select "V2" or "V3" in "()" to determine whether to use LargeV2 for PPG processing or LarheV3 for PPG processing

If you need to do that with crepe（v2）

python svc_preprocessingV2.py -t 2

If you need to do that with crepe（v3）

python svc_preprocessingV3.py -t 2

If you need to do that with rmvpe（v2）

python svc_preprocessingrmvpeV2.py -t 2

If you need to do that with rmvpe（v3）

python svc_preprocessingrmvpeV3.py -t 2

WARNING:Rmvpe might not work, but you can try

-t: threading, max number should not exceed CPU core count, usually 2 is enough. After preprocessing you will get an output with following structure.

```
python prepare/preprocess_zzz.py
```

Train

If fine-tuning is based on the pre-trained model, you need to download the pre-trained model: （LargeV3）sovits5.0.pretrain.pth. （LargeV2）sovits5.0.pretrain.pth.Put pretrained model under project root, change this line
```
pretrain: "./vits_pretrain/sovits5.0.pretrain.pth"
```
in configs/base.yaml，and adjust the learning rate appropriately, eg 5e-5.

batch_szie: for GPU with 6G VRAM, 6 is the recommended value, 8 will work but step speed will be much slower.

Start training

python svc_trainer.py -c configs/base.yaml -n sovits5.0

Resume training

python svc_trainer.py -c configs/base.yaml -n sovits5.0 -p chkpt/sovits5.0/sovits5.0_***.pt

Log visualization
```
tensorboard --logdir logs/
```

Inference

Export inference model: text encoder, Flow network, Decoder network

python svc_export.py --config configs/base.yaml --checkpoint_path chkpt/sovits5.0/***.pt

Inference

if there is no need to adjust f0, just run the following command.（Crepe V2）

python svc_inferencevcrepev2.py --config configs/base.yaml --model sovits5.0.pth --spk ./data_svc/singer/your_singer.spk.npy --wave test.wav --shift 0

if there is no need to adjust f0, just run the following command.（Crepe V3）

python svc_inferencevcrepev3.py --config configs/base.yaml --model sovits5.0.pth --spk ./data_svc/singer/your_singer.spk.npy --wave test.wav --shift 0

if there is no need to adjust f0, just run the following command.（RMVPE V2）

python svc_inferencermvpev2.py --config configs/base.yaml --model sovits5.0.pth --spk ./data_svc/singer/your_singer.spk.npy --wave test.wav --shift 0

if there is no need to adjust f0, just run the following command.（RMVPE V3）

python svc_inferencermvpev3.py --config configs/base.yaml --model sovits5.0.pth --spk ./data_svc/singer/your_singer.spk.npy --wave test.wav --shift 0

if f0 will be adjusted manually, follow the steps:
1. use whisper to extract content encoding, generate test.vec.npy.
```
python whisper/inference.py -w test.wav -p test.ppg.npy
```
1. use hubert to extract content vector, without using one-click reasoning, in order to reduce GPU memory usage
```
python hubert/inference.py -w test.wav -v test.vec.npy
```
1. extract the F0 parameter to the csv text format, open the csv file in Excel, and manually modify the wrong F0 according to Audition or SonicVisualiser
```
python pitch/inference.py -w test.wav -p test.csv
```
1. final inference
```
python svc_inference.py --config configs/base.yaml --model sovits5.0.pth --spk ./data_svc/singer/your_singer.spk.npy --wave test.wav --ppg test.ppg.npy --vec test.vec.npy --pit test.csv --shift 0
```

Notes
- when --ppg is specified, when the same audio is reasoned multiple times, it can avoid repeated extraction of audio content codes; if it is not specified, it will be automatically extracted;
- when --vec is specified, when the same audio is reasoned multiple times, it can avoid repeated extraction of audio content codes; if it is not specified, it will be automatically extracted;
- when --pit is specified, the manually tuned F0 parameter can be loaded; if not specified, it will be automatically extracted;
- generate files in the current directory:svc_out.wav

Train Feature Retrieval Index (Optional)

To increase the stability of the generated timbre, you can use the method described in the Retrieval-based-Voice-Conversion repository. This method consists of 2 steps:

Training the retrieval index on hubert and whisper features Run training with default settings:

python svc_train_retrieval.py

If the number of vectors is more than 200_000 they will be compressed to 10_000 using the MiniBatchKMeans algorithm. You can change these settings using command line options:

usage: crate faiss indexes for feature retrieval [-h] [--debug] [--prefix PREFIX] [--speakers SPEAKERS [SPEAKERS ...]] [--compress-features-after COMPRESS_FEATURES_AFTER]
                                                 [--n-clusters N_CLUSTERS] [--n-parallel N_PARALLEL]

options:
  -h, --help            show this help message and exit
  --debug
  --prefix PREFIX       add prefix to index filename
  --speakers SPEAKERS [SPEAKERS ...]
                        speaker names to create an index. By default all speakers are from data_svc
  --compress-features-after COMPRESS_FEATURES_AFTER
                        If the number of features is greater than the value compress feature vectors using MiniBatchKMeans.
  --n-clusters N_CLUSTERS
                        Number of centroids to which features will be compressed
  --n-parallel N_PARALLEL
                        Nuber of parallel job of MinibatchKmeans. Default is cpus-1

Compression of training vectors can speed up index inference, but reduces the quality of the retrieve. Use vector count compression if you really have a lot of them.

The resulting indexes will be stored in the "indexes" folder as:

data_svc
...
└── indexes
    ├── speaker0
    │   ├── some_prefix_hubert.index
    │   └── some_prefix_whisper.index
    └── speaker1
        ├── hubert.index
        └── whisper.index

At the inference stage adding the n closest features in a certain proportion of the vits model Enable Feature Retrieval with settings:
```
python svc_inference.py --config configs/base.yaml --model sovits5.0.pth --spk ./data_svc/singer/your_singer.spk.npy --wave test.wav --shift 0 \
--enable-retrieval \
--retrieval-ratio 0.5 \
--n-retrieval-vectors 3
```
For a better retrieval effect, you can try to cycle through different parameters: --retrieval-ratio and --n-retrieval-vectors

If you have multiple sets of indexes, you can specify a specific set via the parameter: --retrieval-index-prefix

You can explicitly specify the paths to the hubert and whisper indexes using the parameters: --hubert-index-path and --whisper-index-path

Creat singer

named by pure coincidence：average -> ave -> eva，eve(eva) represents conception and reproduction

python svc_eva.py

eva_conf = {
    './configs/singers/singer0022.npy': 0,
    './configs/singers/singer0030.npy': 0,
    './configs/singers/singer0047.npy': 0.5,
    './configs/singers/singer0051.npy': 0.5,
}

the generated singer file will be eva.spk.npy.
