{"product_id":"2940156711109","title":"Flanging","description":"Flanging \/?flænd???\/ is an audio effect produced by mixing two identical signals together, one signal delayed by a small and gradually changing period, usually smaller than 20 milliseconds. This produces a swept comb filter effect: peaks and notches are produced in the resulting frequency spectrum, related to each other in a linear harmonic series. Varying the time delay causes these to sweep up and down the frequency spectrum. A flanger is an effects unit that creates this effect. In some cases the two signals will become so close that it almost fades away to oblivion called \"sucking air.","brand":"Euprint press Limited","offers":[{"title":"Default Title","offer_id":47114705830128,"sku":"2940156711109","price":1.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940156711109_p0.jpg?v=1764085983","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940156711109","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
