Yet, practitioners need guidelines to choose a method, and while existing benchmarks have been instrumental in advancing the field, larger-scale experiments are needed to guide such choices. First, we show that the clipping levels in existing small-scale benchmarks are moderate and call for benchmarks with more perceptually significant clipping levels. We then propose a general algorithmic framework for declipping that covers existing and new combinations of variants of state-o","authors_text":"Cl\\'ement Gaultier (PANAMA), DANTE), Nancy Bertin (PANAMA), R\\'emi Gribonval (PANAMA, Sr{\\dj}an Kiti\\'c (PANAMA)","cross_cats":["eess.AS","eess.SP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2020-05-19T07:08:18Z","title":"Sparsity-based audio declipping methods: selected overview, new algorithms, and large-scale evaluation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2005.10228","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":"sha256:27169f89423e0bdb519bb65176d32e3c6627e7cb0468f4b1a5b1d928c532d3eb","target":"record","created_at":"2026-07-05T01:55:10Z","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":"f937ce8ce76950179c3ffb768bcb736c89f4dd6f9a3305bdd935c88b201154e7","cross_cats_sorted":["eess.AS","eess.SP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2020-05-19T07:08:18Z","title_canon_sha256":"1e7a10e171b2107da7bad0f406ebb509d5c2e98e587159974a6d2acb81004ebe"},"schema_version":"1.0","source":{"id":"2005.10228","kind":"arxiv","version":2}},"canonical_sha256":"04cebb0291e374455e8dbe535ebdbe129eb0a7cc647814d01740987a53b5dd0f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"04cebb0291e374455e8dbe535ebdbe129eb0a7cc647814d01740987a53b5dd0f","first_computed_at":"2026-07-05T01:55:10.201408Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:55:10.201408Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U3hNXcqET5x39DqNZ0b4+OWTVCzry8VPq8vQok5M4vTE+XEaw1XLC5OLVWV157pqd9MLFaVnOibn9b5YSk6YAA==","signature_status":"signed_v1","signed_at":"2026-07-05T01:55:10.201845Z","signed_message":"canonical_sha256_bytes"},"source_id":"2005.10228","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:27169f89423e0bdb519bb65176d32e3c6627e7cb0468f4b1a5b1d928c532d3eb","sha256:441ab616b53804cf4abb7a114d00d8e7ff101d622e51adfdce4538eec8d3c686"],"state_sha256":"d2d9496c7275aad0930f7b9704b581903f31dd187f3a740cae8cb61bc17c1402"}
