Kwi bitrate elungileyo engaziwayo kuninzi lwaba bonke. Into engayiyo ibuyiselwa, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele eyakuqala.

Kuba i diski imiselwe ibizwa. Umdlali wayefuna ukucofa isandi kwi sixhobo esiqinileyo- somsebenzi ngaphandle kwesoftware kunye nohlaziyo, ngoko ucaciso lwakhetha udidi olunye nediski nganye ecinezelweyo ukusukela oko ithwale. Le yiyo nto umfumani uphatha ngaphandle kokukhathazeka kwaye umkhangeli zincwadi awuzukuncamathisela - udidi lwaye kuphi na apho ixabiso liye khona, naphi na. AC-3 yiDolby Digital, ifomati ejikelezayo emiselwe i-laserdisc, iDVD, i-ATSC yosasazo kunye nefilimu ekuqaleni kweeminyaka ye-90.

Kutheni le nto ifayili yam AC3 ivela ngaphandle kwegama lengoma okanye ubugcisa?

Kuba ifomati ayikho naphi na ukugcina. AC3 yacaciswa ngaphaya kwesandi sayo, ngaphandle kwendawo eqhelekileyo yesihloko, i-albham okanye umfanekiso wesiqulathi seefayili, ngoko abadlali babuyela umva ukuboniswa kwegama lefayili. Ukutshintsha kwifomati ephawulweyo kwenza ithala leencwadi likwazi ukutyelela - ii-tags zibhalwe ngexesha lokuguqula, kunokuba zibuyiselwe, ngoko lindele ukugcwalisa nantoni na eyamkelwa ngumbhali. AC-3 ayisebenzi kakuhle ngemigangatho yangoku kwaye ayivunyelwanga ziibrowser, iifowuni okanye abadlali abaninzi bewebhu ngaphandle kokudibanisa phantsi kwistereo.

Kutheni i AC3 ikwidiski ezininzi kunye nokusasazwa ukuba andizange ndiyikhethe?

Kuba ilayisensiwe kwihardware kunokuba ikhethiwe ngumphulaphuli. Ifomati yacaciswa njengeaudio efunekayo yediski ebonakalayo kunye nemigangatho yosasazo oluzenzekelayo, ngoko wonke umdlali, umfumani kunye nebhokisi ebekwe phezulu ikhowudiwe kwiminyaka emininzi kwaye ishishini lezinto eziquletheyo likhowudiwe kulo ngokuhambelana.

Izixabiso ziyanele: ii CD zesandi zifuna 44. 1 kHz, abanye abadlali be hardware abadala bavuma akukho nto enye, kwaye imibhobho yelizwi ifuna 16 kHz. Cwangcisa umyinge ngokucacileyo kwezi meko kwaye uyishiye ikhululekileyo ngaphandle kokuba.
