Datorzinātne audio rekonstrukcija mūzika mašīnmācīšanās audio kvalitāte bitu dziļums

description

Ņemot vērā to, cik bieži ikdienā sastopamies ar mūziku, kura tiek atskaņota no digitāla audio ieraksta, ir svarīgi, lai šie audio ieraksti ir labā kvalitātē, lai tos būtu patīkami klausīties. Taču dažkārt mums ir pieejams tikai salīdzinoši zemas kvalitātes audio ieraksts. Darbā pētīts, vai, izmantojot mašīnmācīšanos, iespējams uzlabot mūzikas audio ierakstu kvalitāti, palielinot šo ierakstu datu bitu dziļumu. Darba praktiskajā daļā aprakstīts neironu tīkls, kurš cenšas risināt doto problēmu. Neironu tīkls tika apmācīts, un no neironu tīkla tika iegūti apstrādāti audio ieraksti. Pēc iegūtajiem rezultātiem secināts, ka neizdevās būtiski uzlabot doto mūzikas audio ierakstu kvalitāti, taču tiek piedāvātas vairākas idejas, kā doto risinājumu varētu uzlabot nākotnē.
