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 — 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.
