1. **Ensure Git is installed:** This method requires Git to be installed on your system and accessible in your system's PATH.
2. **Execute the installation command:**
```bash
pip install git+[https://github.com/ace-step/ACE-Step.git](https://github.com/ace-step/ACE-Step.git)
pip install git+https://github.com/ace-step/ACE-Step.git
```
It's recommended to use this command within a virtual environment to avoid conflicts with other packages.
Once the installation is complete, you can import and use the ACE-Step API as shown below:
```python
from acestep.api import ACEStep
model = ACEStep()
audio_out = model.infer(
prompt="upbeat pop, catchy melody, female singer",
lyrics="[verse]\nSun is shining bright today\nFeeling happy, come what may",
audio_duration=5.0, # 5 seconds
infer_step=20 # Fewer steps for speed
)
audio_out.save_wav("output.wav")
```
