...stavo nullafacendo in pausa pranzo quando mi č venuta in testa una simpatica idea...perchč non creare un simpatico programmino di utilitā open source...ora per non fare chissā quale cosa pensavo di creare una sorta di kmixer per la regolazione delle impostazioni audio di qualsiasi pc...

...il metodo drawMixerStructure() visualizza a console la struttura dei controlli esposti dalla periferica audio...si tratterebbe soltanto di implementare un piccolo strato swing dinamico che presenti bottoni e slide per il setting dei valori...
...idea troppo malsana?...
