To address this, we propose a dual-branch gated fusion framework that pairs XLSR-53 with CORES, a 66-dimensional descriptor that, unlike prior Linear Filter Bank (LFB)-only work, spans cepstral, oscillatory, rhythmic, energy, and spectral dimensions to capture complementary synthesis artifacts. Our analysis shows XLSR-53 remains discriminative in-domain (ID) while CORES generalizes stably under distribution shift (OOD","authors_text":"Awais Khan, Khalid Malik, Kutub Uddin","cross_cats":["cs.AI","cs.CV"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.SD","submitted_at":"2026-06-08T22:22:48Z","title":"Dual-Branch Gated Fusion for Open-Set Audio Deepfake Source Tracing"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.10223","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:af6dd9ed2fa41e02ad0eacf2600b72982fa939f577eb893935bdcea18493f3ae","target":"record","created_at":"2026-06-10T01:09:00Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"929aec67fde279a03dd3a4f5bdf1678062f709728a50693bbdef1c4313136043","cross_cats_sorted":["cs.AI","cs.CV"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.SD","submitted_at":"2026-06-08T22:22:48Z","title_canon_sha256":"ef40e107c9c45b52e787aee189b56a01f27eb438536022349c3da52c4b4ae704"},"schema_version":"1.0","source":{"id":"2606.10223","kind":"arxiv","version":1}},"canonical_sha256":"9ee4f3de877a3250e1f5571e9a1564dbb0779c7ed06780325d5da7c44d978368","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9ee4f3de877a3250e1f5571e9a1564dbb0779c7ed06780325d5da7c44d978368","first_computed_at":"2026-06-10T01:09:00.417108Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-10T01:09:00.417108Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PYse7K9gpA2KHD5JpkLLrgZLGjeFLWLOPJuNAnIAKZiqUUYnbgKHrXsMwPFE4S5q2hY8eP7Ngr21P/3JLOEJCA==","signature_status":"signed_v1","signed_at":"2026-06-10T01:09:00.417988Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.10223","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:af6dd9ed2fa41e02ad0eacf2600b72982fa939f577eb893935bdcea18493f3ae","sha256:23b544ed5f013a7ef46ce3fd2b8319b9c95aecd7d6650e13e126c5e7205dfe17"],"state_sha256":"4e4db0101747ccc6d4c451cf9750c665a7ea3b032dfae43becaf0d248d526039"}
