## Overview

**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).

## Features

- **Zero-shot synthesis**: Generate singing voices for unseen singers without fine-tuning
- **Melody-conditioned control**: Use F0 contour for pitch guidance
- **Score-conditioned control**: Use MIDI notes for precise musical notation
- **High-fidelity output**: Realistic vocal synthesis with natural expression
- **Safetensors format**: Optimized model weights in bf16 + fp32 precision
