# Footstep Detection Dataset — 50 Hours of Real Footstep Audio

**50 hours of real footstep audio recordings** for training footstep detection, sound event detection, and audio classification models. 166 manually verified files captured in natural indoor and outdoor conditions, with per-file metadata on surface, footwear, location, and background noise. The largest publicly listed footstep audio dataset — 3–5× larger than academic benchmarks (AFPILD: 10h, AFPID-II: 14h).

## Quick Start — Loading with 🤗 Datasets

```python
from datasets import load_dataset

dataset = load_dataset("AxonData/footstep-detection-dataset")
print(dataset)

sample = dataset["train"][0]
print(sample["audio"])           # audio array + sampling_rate
print(sample["surface"])         # e.g. "wood_laminate"
print(sample["footwear"])        # e.g. "sneakers"
print(sample["noise_level"])     # e.g. "low"
```

## Quick Start — PyTorch DataLoader

```python
import torch
import torchaudio
from datasets import load_dataset

ds = load_dataset("AxonData/footstep-detection-dataset", split="train")

def collate(batch):
    waveforms = [torch.tensor(item["audio"]["array"]) for item in batch]
    labels = [item["surface"] for item in batch]
    return waveforms, labels

loader = torch.utils.data.DataLoader(ds, batch_size=8, collate_fn=collate)
```

## Sample vs Full Version

This HuggingFace repository contains a **sample subset** for evaluation. The full 50-hour dataset is licensed for commercial use through Axon Labs.

**Full version of dataset is available for commercial usage — leave a request on our website [Axonlabs](https://axonlab.ai/dataset/footsteps-audio-dataset/?utm_source=hugging-face&utm_medium=cpc&utm_campaign=footstep&utm_content=readme) to purchase the dataset 💰**

## What Makes This Dataset Unique

- **Largest footstep audio corpus available commercially** — 3–5× larger than the most cited academic alternatives
- **Manually verified, not scraped** — every file reviewed for clear footstep audibility
- **Real smartphone recordings** — matches deployment conditions for smart speakers, phones, wearables
- **Structured metadata across 4 dimensions** — supports filtered training and multi-task learning
- **Backed by a biometric AI specialist** — Axon Labs builds datasets used by 21% of iBeta 2025 certified companies

## Two Dataset Versions Available

- **Sample Version** — open subset for EDA, evaluation, and proof-of-concept (this repo)
- **Full Version** — 50 hours of audio with complete metadata, licensed for commercial training

## FAQ

**Q: What's the largest publicly available footstep audio dataset?**
This one — 50 hours of curated recordings, 3–5× larger than AFPILD (10h) or AFPID-II (14h), which are the most cited academic benchmarks in the field. Sound event datasets like FSD50K and ESC-50 contain footsteps only as a small subset (under 1,000 samples).

**Q: Can I use this dataset for footstep biometrics / acoustic person identification?**
Yes. The dataset is well-suited for footstep biometrics research, especially as a pre-training corpus. For per-subject identification tasks, we can collect additional per-subject sessions on request through our custom data collection service.

**Q: What surfaces and footwear are covered?**
6 surface types (wood/laminate, tile, carpet, concrete/asphalt, stairs, other) and 6 footwear types (barefoot, slippers, sandals, sneakers, dress shoes/boots, other). Every file is labeled across both dimensions.

**Q: Is the data ethically collected?**
Yes. All recordings were captured with explicit participant consent and processed in accordance with GDPR. Full documentation of consent and provenance is available for the commercial version.
