**SoulX-Singer** is a high-fidelity, zero-shot singing voice synthesis model that enables users to generate realistic singing voices for unseen singers. It supports melody-conditioned (F0 contour) and score-conditioned (MIDI notes) control for precise pitch, rhythm, and expression.

For more details, please refer to the paper: [SoulX-Singer: Towards High-Quality Zero-Shot Singing Voice Synthesis](https://arxiv.org/abs/2602.07803).

## Sample Usage

### 1. Set Up Environment

```bash
git clone https://github.com/Soul-AILab/SoulX-Singer.git
cd SoulX-Singer
conda create -n soulxsinger -y python=3.10
conda activate soulxsinger
pip install -r requirements.txt
```

### 2. Download Pretrained Models

```bash
pip install -U huggingface_hub

# Download the SoulX-Singer SVS model
hf download Soul-AILab/SoulX-Singer --local-dir pretrained_models/SoulX-Singer

# Download models required for preprocessing
hf download Soul-AILab/SoulX-Singer-Preprocess --local-dir pretrained_models/SoulX-Singer-Preprocess
```

### 3. Run Inference

```bash
bash example/infer.sh
