recording has 1 distinct synonym spread across 1 of its 3 senses. Each sense below keeps its own list, because a synonym belongs to a meaning and not to a word: swapping one sense's substitute into another sense's sentence is how a thesaurus makes writing worse. WordNet records no antonym for it — antonymy is a relation between word forms rather than concepts, so it is deliberately sparse.
Counts are distinct word forms across every sense. A synonym that appears under three senses is counted once here and shown three times below, under each sense it belongs to.
a signal that encodes something (e.g., picture or sound) that has been recorded
the act of making a record (especially an audio record)
“she watched the recording from a sound-proof booth”
a storage device on which information (sounds or images) have been recorded
Synonyms, antonyms and the broader and narrower relations for recording come from Princeton University’s WordNet. Full sources and licences.
