Bridging the Synthetic-to-Real Gap in Impulsive Sound Detection Using Audio Transfer Learning

A CNN achieving 98.4% F1 on synthetic benchmark spectrogram data collapses to 20.0% F1 on real-world audio, revealing a severe synthetic-to-real domain gap in impulsive sound detection. This paper provides one of the first quantitative studies of this phenomenon and demonstrates that representation choice dominates cla...
