# Field Noise Samples

Place `.wav` audio files here to enable realistic field-noise augmentation during training.

## Required Files (16kHz mono, any duration ≥5s)
- `tractor_engine.wav` — diesel tractor idling or working
- `wind_field.wav` — wind in open farmland
- `livestock_ambient.wav` — cattle, goats, or chickens in background

## Suggested Sources
- [Freesound.org](https://freesound.org) — search "tractor", "wind field", "livestock ambient" (filter by CC0 / CC-BY)
- Field recordings from partner NGOs or agricultural organizations in Mali/Guinea

## Licensing Note
Ensure all audio files are licensed for use in ML training datasets.
CC0 (public domain) or CC-BY are preferred.

## Without Noise Files
The augmenter will fall back to Gaussian noise only.
Training will still work but model robustness to real-world conditions may be reduced.
