...HwUp...open source...JMixer...

[ally]

...stavo nullafacendo in pausa pranzo quando mi è venuta in testa una simpatica idea...perchè non creare un simpatico programmino di utilità open source...ora per non fare chissà 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?...

L'idea del progetto open source mi piace, magari fare qualcosa di piu utile ed interessante...:rolleyes:

...l'idea è quella di sviluppare un programma estremamente semplice...robetta da un paio di giorni di lavoro usando il tempo libero...magari se la cosa funge cimentarsi in qulacosa di piu' evoluto...lungi da me replicare un diamond...

...ciao...

[isAlreadyInUse]

Io passere direttamente oltre

Io passere direttamente oltre

vabbè però non si può tagliare le gambe così alla gente....:rolleyes:

[isAlreadyInUse]

Ma mica le mie opinioni sono legge :D

[orpheus]

Secondo me è una bella idea..

e sono d'accordo anche di passare dal semplice a difficile.

Ho visto mille volte progetti iniziati con i miei amici che vanno in fumo perché c'è poco tempo e dilungando troppo le cose non avere in mano niente non stimola a proseguire


tengo l'orecchio teso in ascolto :D
