Few sounds make a viewer physically uncomfortable as quickly as the wrong kind of scrape — fingernails on a blackboard works because evolution built a specific aversion to that frequency band. These 12 scraping audio clips work the full discomfort range: metal scraping sound effect material with the abrasive high-end intact, wood scratch from coarse texture against finer grain, concrete drag of something heavy being pulled across a hard surface, and the duller plastic scuff of softer materials in contact.
Horror editors reach for the metal-on-metal scrape because it triggers a body response before the audience can process it visually — pair it with a slow zoom and the tension does itself. Foley editors use the wood and concrete drag material for furniture-moving and prop-handling scenes. For sci-fi work, layer the metal scrape with a low sub-bass drone and the same recording becomes a hull breach. Free to download for foley and horror sting work, no signup or licence chase.
