Data for Pre-Filtering Gunshot Acoustics for Robust Training Data in Open-Set Ecological Sound Classification

Data consist of 55 acoustic recordings collected using Autonomous Recording Units (ARUs) from two locations and sampling periods. Specifically, data include 60-minute WAV files (8 folders, each contains 5 WAV files) from a field trial during February 2025 whereby we shot shotguns at varying distance from ARUs at Emiquon Reserve owned by The Nature Conservancy. Data also include 60-minute WAV files (15 WAV files) from one ARU placed at Big Rice Lake State Fish and Wildlife Area on opening day of waterfowl hunting season during 10-26-2024. Filenames include the ARU ID separated by underscores and the associated date and time e.g., MINI10_20241026_060002.wav was from MINI10 on 10/26/24 at 6 AM.
