The system fed 10-second raw-waveform clips into a pretrained PaSST spectrogram transformer, with data split by original song to prevent leakage between train and test sets. At the video level, the final detector reached 0.811 balanced accuracy. Clip-level results split unevenly: AI-generated clips scored an F1 of 0.836, while edited clips lagged at 0.720.\n\nThat gap matters because edited audio - pitch-shifted, re-encoded, remixed - is exactly what shows up in real uploads, not pristine studio files. A detector that struggles to tell a remix from a synthetic track will misfire on ordinary human-made content once it leaves a controlled test set. The researchers also ran Grad-CAM visualizations to check whether confident predictions were keying on specific time-frequency regions of a clip rather than reacting to the whole thing.\n\nDetection tools keep getting graded on tidy datasets; real platforms are messier, and messier is where these numbers will actually be tested.","[\"ai music detection\",\"deepfakes\",\"audio forensics\",\"machine learning\"]","2026-08-18T04:00:00.000Z","2026-08-18T15:29:40.728Z","2026-08-18T15:29:52.611Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The closing sentence claims the researchers 'already suspect these results may not hold once the audio leaves the lab' based on their Grad-CAM check, but the source only says Grad-CAM was used to inspect whether predictions rely on localized time-frequency regions -- there is no such stated suspicion or conclusion in the source, so this unsupported claim must be cut or replaced with a properly sourced closing line.","resolved","ai",[32,33,34,35],"ai music detection","deepfakes","audio forensics","machine learning",[37],{"name":38,"url":39},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.14916",0,{"sections":42},[43,47,51,56,61,66,71,76,81,85,90,95,100,105],{"name":44,"slug":30,"count":45,"latest_published_at":46},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":46},"Security","security",435,{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":18},"Dev Tools","dev-tools",69,{"name":86,"slug":87,"count":88,"latest_published_at":89},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":106,"slug":107,"count":108,"latest_published_at":109},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
