eq

Navrhněte a implementujte pásmový ekvalizátor pro filtraci zvukových souborů (např. formát WAV) a též zvuku v reálném čase. Ekvalizátor by měl mít nejméně 8 regulovatelných pásem (tvar pásem libovolný, iniciiativě se meze nekladou). Předpokládá se vytvoření grafického uživatelského rozhraní pro ovládání ekvalizátoru a též pro zobrazování parametrů zpracovávaného zvuku.
