Descriptor: Certus Caliber Classification Gunshot Dataset (C3GD)

The Certus Caliber Classification Gunshot Dataset (C3GD) has been released, consisting of over 8000 field-collected audio samples from 28 firearms across 16 calibers, with extensive metadata. This dataset is designed for caliber classification but also supports applications in gunshot detection, audio separation, and signal processing, addressing the limitations of existing datasets that often suffer from low quality and label noise. Its real-world diversity and comprehensive metadata make it a valuable resource for practitioners developing robust audio analysis models in firearm sound classification.
