Dual-Engine Survives MP3 for AI Music Detection
💡Novel hybrid detector beats compression pitfalls—essential for real-world AI audio forensics
⚡ 30-Second TL;DR
What Changed
CNN on mel-spectrograms breaks under MP3 compression losing spectral artifacts
Why It Matters
Enhances reliable AI music detection for platforms handling compressed files, reducing misinformation risks. Extends to hybrid models for other adversarial robustness challenges in audio ML.
What To Do Next
Integrate Demucs into your audio pipeline to test reconstruction errors on AI vs human music samples.
Key Points
- •CNN on mel-spectrograms breaks under MP3 compression losing spectral artifacts
- •Demucs separates into vocals/drums/bass/other stems then remixes to measure error
- •Human music shows high reconstruction error from recording bleed; AI shows low
- •Hybrid: CNN for confident cases, reconstruction for uncertain—saves compute
- •80%+ AI detection, 1.1% human FPR, codec-agnostic (MP3/AAC/OGG)
