| + | === Detalii === | ||
| + | |||
| + | Esantionarea si prelucrarea datelor audio se face in cadr-ul unei intreruperi pe **//"Timer1"//** setata la o frecventa de 22khz. | ||
| + | |||
| + | {{ :pm:prj2023:alexau:timer_code.png?nolink&600 |}} | ||
| + | |||
| + | In Cadrul functiei **//"setup()"//** se activeaza inputurile , se activeaza clasele si se calculeaza timpul pentru generarea intreruperii. | ||
| + | |||
| + | {{ :pm:prj2023:alexau:setap_audio_thingy.png?nolink&600 |}} | ||
| + | |||
| + | Functia **//"loop()"//** este folosita pentru debug, citirea dispozitivelor de intrare (butoane/potentiometre) si afisarea de mesaje la LCD. | ||

| + | |||
| + | ===== Concluzii ===== | ||
| + | |||
| + | In urma implementarii rezulta ca arduino NU este o platforma buna pentru aplicatii audio, frecventa mica de procesor nu permite analiza furie real time a sunetului, prin urmare trebuie folosite "hack-uri" pentru a modela sunetul. | ||
| + | |||
| + | **O IMPARTIRE IA MAI MULT DECAT E PERIOADA DE ESANTIONARE (22KHZ)!** | ||
| + | |||
| + | Aplicarea mai multor efecte pe un esantion s-a dovedit prea costisitoare asa ca produsul rezultat poate aplica un singur efect la orice moment de timp. (Efectele pot fi aplicate atat real-time cat si pe datele tip playback). | ||
