想做枪声分类或检测的朋友，这个 C3GD 数据集有 8000+ 现场样本、28 种枪和 16 种口径，比网上扒的数据干净多了。
C3GD 是一个公开的枪声数据集，包含超过 8000 个现场采集的枪声数据点，覆盖 28 种枪支和 16 种口径。数据集提供了远超现有公开资源的元数据，包括麦克风类型、位置等细节。它主要面向口径分类任务，也可用于枪声检测、音频分离和音频信号处理，旨在提高真实场景下的泛化能力。该数据集解决了互联网收集枪声音频带来的低质量和标签噪声问题。
Descriptor: Certus Caliber Classification Gunshot Dataset (C3GD)
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 gunshot audio collected from the internet, which increases the risk of low-quality data and label noise. This dataset is primarily focused on caliber classification, but can also be used for gunshot detection, audio separation, and audio signal processing, providing a diversified and real-world reference. The dataset aims to provide enough diversity to be able to generalize to more real-world applications while also providing enough metadata for detailed academic analysis.
