# Clotho-Moment
This repository provides wav files used in [Language-based Audio Moment Retrieval](https://arxiv.org/abs/2409.15672).

Each sample includes long audio containing some audio events with the temporal and textual annotation.

Project page: https://h-munakata.github.io/Language-based-Audio-Moment-Retrieval/
Code: https://github.com/line/lighthouse

## Split
- Train
  - train/train-{000..715}.tar
  - 37930 audio samples
- Valid
  - valid/valid-{000..108}.tar
  - 5741 audio samples
- Test
  - test/test-{000..142}.tar
  - 7569 audio samples

## Using Webdataset
```python
import webdataset as wds

url = "https://huggingface.co/datasets/lighthouse-emnlp2024/Clotho-Moment/resolve/main/train/train-{{001..002}}.tar"
url = f"pipe:curl -s -L {url}"
dataset = wds.WebDataset(url, shardshuffle=None).decode(wds.torch_audio)

for sample in dataset:
    print(sample.keys())
```
