Much of this research investigates separating speech from noise, speech from speech, musical instruments from each other, or sound events from each other. In this paper, we focus on the cocktail fork problem, which takes a three-pronged approach to source separation by separating an audio mixture such as a movie soundtrack or podcast into the three broad categories of speech, music, and sound effects (SFX ","authors_text":"Aswin Shanmugam Subramanian, Darius Petermann, Gordon Wichern, Jonathan Le Roux, Zhong-Qiu Wang","cross_cats":["cs.SD"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.AS","submitted_at":"2022-12-14T16:47:43Z","title":"Tackling the Cocktail Fork Problem for Separation and Transcription of Real-World Soundtracks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.07327","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":"sha256:33746444dfbb8b6faf7fe9f23204eb2a0c172a3e49d5ac4b031c3f21804074c0","target":"record","created_at":"2026-07-05T05:25:23Z","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":"5b671ef6ebf541ad0367ebaee26fea733c62c2c8b48c8d4de53db69d85cebb0b","cross_cats_sorted":["cs.SD"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.AS","submitted_at":"2022-12-14T16:47:43Z","title_canon_sha256":"5ec19f68ee9aab200a5e0bdcdb8e64ceff759125a059932f062c94fe773d5ec6"},"schema_version":"1.0","source":{"id":"2212.07327","kind":"arxiv","version":1}},"canonical_sha256":"761369605101b556650a1dd6db0c8923423007e0b1ca8fb597d06209c4f55959","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"761369605101b556650a1dd6db0c8923423007e0b1ca8fb597d06209c4f55959","first_computed_at":"2026-07-05T05:25:23.961461Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:25:23.961461Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eUVK+9CZ+Mlbgp/wthEnjLk99IOHr1e6U3Kr+bM8mBXORRuoLMEPmfb7PmXoGNiKzdW1Rnnu1ZAWMbR+kOt7Cw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:25:23.961866Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.07327","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:33746444dfbb8b6faf7fe9f23204eb2a0c172a3e49d5ac4b031c3f21804074c0","sha256:d5ebbdef3bf2e763410d3664dd4a05bc566dd01e8fea8b592c53ac7195e74a5c"],"state_sha256":"ec9b9dafa153b32a3d1a01942721d0a9ae2780fdb51e6e5023248b1dce94a3ca"}
