# PhyAV-Sound-11K

This is the official release of the **PhyAV-Sound-11K** dataset introduced in the paper:
**[PhyAVBench: A Challenging Audio Physics-Sensitivity Benchmark for Physically Grounded Text-to-Audio-Video Generation](https://arxiv.org/abs/2512.23994)**.

All videos in this dataset are released without audio. To prevent potential data leakage, the ground-truth audio files are not publicly released. Instead, we provide the corresponding ground-truth audio embeddings (**CLAP** and **ImageBind**) to support reproducible evaluation.

## Data Organization

- `prompt_all.jsonl`: 337 variable-controlled prompt groups.
- `videos_gt_silent_part_0-1`: 11,605 silent videos.
- `ref.lst`: a list of reference videos, mainly used for video-to-audio generation.
- `ref_first_frames`: first-frame images extracted from the reference videos, mainly used for image-to-video generation.
- `embeddings`: 377 embedding direction vectors (**CLAP** and **ImageBind**), computed from the audio of all 11,605 ground-truth videos and averaged within each group.

## Evaluation Code

Please visit <https://github.com/imxtx/PhyAVBench>, which provides:

- Evaluation code.
- Evaluation prompts.
- Ground-truth audio embedding direction vectors.
