Tim nau\u010dnika s MIT-a, Adobe i Microsofta razvili su novu metodu kojom mogu rekonstruisati zvuk iz vizuelnih informacija. Snimaju\u0107i vibracije vre\u0107ice \u010dipsa, biljke i aluminijske folije uspjeli su rekonstruisati zvuk pomo\u0107u tih objekata koriste\u0107i odgovaraju\u0107e algoritme koji analiziraju vibracije objekata snimljenih na videu.<\/p>\n\n\n\n

Metoda se temelji na tome da objekti izlo\u017eeni zvukovima proizvode sitne vibracije nevidljive golim okom, te da bi se dobio audio zapis nau\u010dnici su koristili normalne i \u201ehigh-speed\u201c kamere. Tako\u0111er su otkrili da se kvaliteta audio zapisa mo\u017ee zna\u010dajno pove\u0107ati ako je broj slika po sekundi ve\u0107i od frekvencije audio signala.<\/p>\n\n\n\n

S tim da je svaki objekat druga\u010diji, metoda je razvijena tako da uzima u obzir i mehani\u010dka svojstva snimljenog objekta i njegove pokrete, kako bi rekonstruisani audio zapis bio \u0161to sli\u010dniji orginalnom. Takav na\u010din rekonstrukcije zvuka usput daje i mnogo informacija o samom objektu, jer se svaki objekt druga\u010dije pona\u0161a tijekom izlaganja razli\u010ditim zvu\u010dnim vibracijama.<\/p>\n\n\n\n
