Existing onset detection methods are based on temporal/spectral analysis, or methods that integrate temporal and spectral information together with statistical estimation and machine learning models. In this paper, we propose a method to localize onset components in music by using the S-transform, and thus, the method is purely based on temporal/spectral data. Unlike the other methods based on temporal/spectral data, which usually rely short time Fourier transform (STFT), our method enables effective isolation of crucial f","authors_text":"Carlo Fischione, Chathuranga Weeraddana, Nishal Silva","cross_cats":["cs.SD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2017-12-07T11:22:55Z","title":"On Musical Onset Detection via the S-Transform"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.02567","kind":"arxiv","version":2},"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":"sha256:3dbb3c734e304dac11777250c0cdbaa90446ee2131f2074f17e8d48f2f951642","target":"record","created_at":"2026-05-17T23:59:43Z","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":"e11a83a8bce8c1538c035c3a3d9917dc5a352eda4f5ae252c594f88e5d8acf4b","cross_cats_sorted":["cs.SD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2017-12-07T11:22:55Z","title_canon_sha256":"d00ea9ad504032019405dfd8b7d5d81a34cc2b9285ea9e927742c10ee0ff5eae"},"schema_version":"1.0","source":{"id":"1712.02567","kind":"arxiv","version":2}},"canonical_sha256":"bad3ca1b16a3209fce53c173ec401f931999cf1a103edb7415688b97602f29a5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bad3ca1b16a3209fce53c173ec401f931999cf1a103edb7415688b97602f29a5","first_computed_at":"2026-05-17T23:59:43.869777Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:43.869777Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"icYdejfTlRT4pSdt+VTxgd52Q8L7HOWR0cGojDeJlxMKhCROkGDlYqlnDC7iJB9hlv14bH4VV0Ud5PVpOr46Cw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:43.870257Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.02567","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3dbb3c734e304dac11777250c0cdbaa90446ee2131f2074f17e8d48f2f951642","sha256:6cd81d867868bf0d858c84cf07ecb9d70207504cb5fcc3331566f386025bf6fa"],"state_sha256":"50e9b53c9ab2a8ab26be25126e6aa100dc11de0eba70dbfea2d6275e9cc32027"}
