+### RWAVS Dataset
+We provide the Real-World Audio-Visual Scene (RWAVS) Dataset.
+
+1. The dataset can be downloaded from this Hugging Face repository.
+
+2. The data is organized with the following directory structure.
+    ```
+    ./release/
+    ├── 1
+    │   ├── binaural_syn_re.wav
+    │   ├── feats_train.pkl
+    │   ├── feats_val.pkl
+    │   ├── frames
+    │   │   ├── 00001.png
+    |   |   ├── ...
+    │   │   ├── 00616.png
+    │   ├── source_syn_re.wav
+    │   ├── transforms_scale_train.json
+    │   ├── transforms_scale_val.json
+    │   ├── transforms_train.json
+    │   └── transforms_val.json
+    ├── ...
+    ├── 13
+    └── position.json
+    ```
+
+    The dataset contains 13 scenes indexed from 1 to 13. For each scene, we provide
+    * `transforms_train.json`: camera poses for training.
+    * `transforms_val.json`: camera poses for evaluation. We split the data into `train` and `val` subsets with 80% data for training and the rest for evaluation.
+    * `transforms_scale_train.json`: normalized camera poses for training. We scale 3D coordindates to $[-1, 1]^3$.
+    * `transforms_scale_val.json`: normalized camera poses for evaluation.
+    * `frames`: corresponding video frames for each camera pose.
+    * `source_syn_re.wav`: single-channel audio emitted by the sound source.
+    * `binaural_syn_re.wav`: two-channel audio captured by the binaural microphone. We synchronize `source_syn_re.wav` and `binaural_syn_re.wav` and resample them to $22050$ Hz.
+    * `feats_train.pkl`: extracted vision and depth features at each camera pose for training. We rely on V-NeRF to synthesize vision and depth images for each camera pose. We then use a pre-trained encoder to extract features from rendered images.
+    * `feats_val.pkl`: extracted vision and depth features at each camera pose for inference.
+    * `position.json`: normalized 3D coordinates of the sound source.
+
+    Please note that some frames may not have corresponding camera poses because COLMAP fails to estimate the camera parameters of these frames.
