AC3 (Dolby Digital) is a multi-channel surround sound audio format.
Ha se kamehla — ke bitstream ea ho fana ka lifilimi. AC3 stream e na le ho kopanya li-channel tse ngata tse nahanang ho decode ka mofani oa AV le ho romelloa ho li-speakers tse 'nete tse kentsoeng ka kamoreng. Telephony kapa laptop e tlameha ho e kopanya ho li-channel tse peli pele e ka bapala ka ho feletseng, le hore downmix e ka ba e le ntle le e le ntle ho feta hlooho ea stereo e mastered e le stereo. E fetole haeba sebaka se ka sehloohong ke headphones; e boloka haeba sebaka se ka sehloohong ke receiver. Li-DVD li na le li-DVD-ROM, li-DVD-ROM li na le li-DVD-ROM, li-DVD-ROM li na le li-DVD-ROM, li-DVD-ROM li na le li-DVD-ROM.
Ho sa tsotelehe hore na encoder ea mantlha e entse qeto ea ho e tlosa,'me ha e ka khutlisoa. AC3 e kopanya ka ho etsa hore eng eo hlooho e ke keng ea e bona - li-sounds tse sireletsehileng li lula ka tlase ho tse matla, li-frequencies ka lehlakoreng la ho utloa - le ho e tlosa ka ho sa feleng. Ka bitrate e phetseng hantle e sa utloahaleng ho batho ba bangata. Seo e seng sona se ka khutlisoa, ka hona ho fetola ho formate e sa hlokeng ho boloka boemo ba hona joale ho feta ho khutlisa sehlooho se kaholimo. AC-3 ke audio e nang le li-multichannel tse ngata, ka linako tse ling 5.1 ho 384 kapa 448 kbps, le metadata bakeng sa ho arolelana le ho downmixing.
Ka lebaka la hore listandart tsa diski li ne li e bitsa.

Ke ka hona motsamaisi a e etsang ka ho sa tsitsang'me mohlophisi ha a e phele - mofuta o ne o le teng moo listandart li neng li le teng, le moo ho seng teng. AC-3 ke Dolby Digital, e leng mofuta oa surround o sebelisoang ka laserdisc, DVD, ATSC le lifiliming ka bo-1990.
Ka lebaka la hore e na le laesense ho hardware ho feta ho e khethoa ke moqoqisi.

Haeba u e utloa e le li-surround e itšetlehile ka ho qetela: mofuputsi o tla decode li-channel tsohle, mohala o tla koaloa ka nako ea ho bapala ntle le ho tšoenyeha. Ho fetola ho mofuta oa stereo feela ho etsa hore ho koaloa ho be le nako e telele.
Age ka boeona ha se bothata - li-formats tse ngata ho tloha ka nako eo li ntse li le ntle ka ho feletseng, ka nepo hobane tsohle li na le lilemo tse makholo ho li phethela. Seo se lokelang ho etsoa ke seo nako e neng e e-na le sona: lifaele tse nyane, processors tse nyane, ha ho na marang-rang, le li-features ha ho motho ea hlokang ho fihlela joale.
