Existuje n\u011bkolik technik, jak zjistit, zda v\u00e1\u0161 zesilova\u010d clippinguje. M\u016f\u017eete za\u010d\u00edt poslechem d\u0159\u00edve popsan\u00e9ho zkreslen\u00e9ho zvuku.

Vizu\u00e1ln\u00ed kontrolou lze clipping tak\u00e9 rozeznat. Na mnoha zesilova\u010d\u00edch jsou indik\u00e1tory LED, kter\u00e9 se rozsv\u00edt\u00ed, kdy\u017e zesilova\u010d clipuje. Obvykle se tyto p\u0159\u00edznaky ozna\u010duj\u00ed jako „clip“ nebo „overload“. Tyto kontrolky blikaj\u00ed nebo z\u016fst\u00e1vaj\u00ed st\u00e1le jasn\u00e9, co\u017e znamen\u00e1, \u017ee v\u00e1\u0161 zesilova\u010d je clipping. Nakonec m\u016f\u017eete otestovat pr\u016fb\u011bh a hledat p\u0159\u00edpadn\u00e9 clippingy pomoc\u00ed osciloskopu nebo audioanalyz\u00e1toru.
