## Setup
```bash
pip install auv
wget https://huggingface.co/SWivid/AUV/resolve/main/auv.pt
```

## Inference
Command line usage, reconstruct all `.wav` files under the `input-dir` and write to the `output-dir`:
```bash
auv-infer --input-dir INPUT_WAV_DIR --output-dir OUTPUT_WAV_DIR --ckpt CKPT_PATH
# if torch.bfloat16 inference: --bf16
# if need to assign gpu: --device cuda:0
```

Python script usage see [`src/auv/infer.py`](https://github.com/SWivid/AUV/blob/main/src/auv/infer.py).
