Learning the Beauty in Songs: Neural Singing Voice Beautifier

This repository is the official PyTorch implementation of our ACL-2022 paper.

0. Dataset (PopBuTFy) Acquirement

Audio samples

• You can download the dataset from here. Please send us an email for registration (See in apply_form).
• Dataset preview.

Text labels

NeuralSVB does not need text as input, but the ASR model to extract PPG needs text. Thus we also provide the text labels of PopBuTFy.

1. Preparation

Environment Preparation

Most of the required packages are in https://github.com/NATSpeech/NATSpeech/blob/main/requirements.txt

Or you can prepare environments with the Requirements.txt file in the repository directory.

pip install Requirements.txt

Data Preparation

1. Extract embeddings of vocal timbre:

   CUDA_VISIBLE_DEVICES=0 python data_gen/tts/bin/binarize.py --config egs/datasets/audio/PopBuTFy/save_emb.yaml
   

2. Pack the dataset:

   CUDA_VISIBLE_DEVICES=0 python data_gen/tts/bin/binarize.py --config egs/datasets/audio/PopBuTFy/para_bin.yaml
   

Vocoder Preparation

We provide the pre-trained model of HifiGAN-Singing which is specially designed for SVS with NSF mechanism.

Please unzip pre-trained vocoder into checkpoints before training your acoustic model.

This singing vocoder is trained on 100+ hours singing data (including Chinese and English songs).

PPG Extractor Preparation

We provide the pre-trained model of PPG Extractor.

Please unzip pre-trained PPG extractor into checkpoints before training your acoustic model.

After the instructions above, the directory structure should be as follows:

.
|--data
    |--processed
        |--PopBuTFy (unzip PopBuTFy.zip)
            |--data
                |--directories containing wavs
    |--binary
        |--PopBuTFyENSpkEM
|--checkpoints
    |--1009_pretrain_asr_english
        |--
        |--config.yaml
    |--1012_hifigan_all_songs_nsf
        |--
        |--config.yaml

2. Training Example

CUDA_VISIBLE_DEVICES=0,1 python tasks/run.py --config egs/datasets/audio/PopBuTFy/vae_global_mle_eng.yaml --exp_name exp_name --reset

3. Inference

Inference from packed test set

CUDA_VISIBLE_DEVICES=0,1 python tasks/run.py --config egs/datasets/audio/PopBuTFy/vae_global_mle_eng.yaml --exp_name exp_name --reset --infer

Inference results will be saved in ./checkpoints/EXP_NAME/generated_ by default.

We provided:

• the pre-trained model of NSVB (en version);

Remember to put the pre-trained models in checkpoints directory.

Inference from raw inputs

WIP.
