Descriptor: Certus Caliber Classification Gunshot Dataset (C3GD)

arXiv:2606.18135v1 Announce Type: cross Abstract: In this work, we introduce the Certus Caliber Classification Gunshot Dataset (C3GD), a publicly accessible data set developed for the analysis of firearm muzzle blast sounds. The dataset aims to provide a wide variety of firearms, calibers, cartridges, microphones, and microphone locations with metadata detailed beyond what is currently otherwise available. It comprises more than 8000 field-collected data points from 28 firearms across 16 calibers. Because data collection in the field is costly, much of the existing research has been done using

Why this matters
Why now

The continuous advancements in AI and machine learning necessitate high-quality, specialized datasets for specific applications like acoustic classification, especially as defense and security technologies evolve.

Why it’s important

This dataset significantly enhances the ability to accurately identify and classify firearm discharges, critical for acoustic surveillance, security, and potentially integrating into autonomous defense systems.

What changes

The availability of a publicly accessible, highly detailed gunshot dataset with extensive metadata improves the training and robustness of AI models for acoustic threat detection and classification.
