AC3 Chishanduri

Hapana chinhu - icho chinamato chekutumira bitstream. A AC3 stream inotakura multichannel mix inotarisirwa kudzokororwa neAV mushandisi uye kuendeswa kune zvakajairika vataura vakaiswa munzvimbo yeimba. The phone or a laptop has to fold it down to two channels before it can play at all, and that downmix is often quieter and flatter than a stereo track mastered as stereo. Convert it if the destination is headphones; keep it if the destination is a receiver. AC-3 ndiyo surround track iyo yega yega AV receiver, DVD player uye TV inowana, saka ndiyo ichiri basa rekutanga rekuburitsa.

Chii chatinenge tichifunga kuti chaive chakakosha, asi chakanga chisina kuwanikwa. AC3 chinomanikidza nekuisa zvinyorwa zvacho mumifananidzo, izvo ziso harichazvione - mabhureki anomira pasi pezvombo zvakanyanyisa, mafrequencies panzvimbo dzekunzwa - uye kubvisa zvachose. Pachimiro chehutano bitrate iyo haisi kutaurwa kune vese. Chii chisina kutaurwa chinogona kudzoreredzwa, saka kushandura kune lossless format inochengeta ikozvino mamiriro sezviri nyore kupfuura kudzoreredza zvakanyorwa. AC-3 imhando yemultichannel audio, iyo inowanzo shandiswa pa5.1 at 384 or 448 kbps, ine metadata yekuti mashoko aite sezvinoita.

Mutambi aifanira kubvisa mavara ezvokutaura muhardware ine basa rakajairika, pasina software kana kuvandudzwa, saka zvinyorwa zvakatora imwe fomati uye pakanga paine fomati yese yakanga yaiswa. Izvi ndizvo zvakaita kuti mushandisi akwanise kuishandisa pasina kukanganwa, uye browser haizoibata — fomati yakanga yaenda kunzvimbo dzose dzaiendawo, uye hapana imwe nzvimbo. AC-3 iDolby Digital, iyo surround format yakagadzirirwa kuLaserdisc, DVD, ATSC kutumira uye cinema mukutanga kwe1990s.

Nekuti format haina nzvimbo yekuchengeta mazita aya. AC3 yakanyorwa pamusoro pezvombo, pasina nzvimbo yekuti uwane zita, album kana kuti bhokisi rezvinyorwa, saka vatambi vanoramba vachiratidza zita refaira. Kushandura kuita format ine mazita ndechimwe chezvinhu zvinoita kuti library ikwanise kushanyira — mazita anonyorwa panguva yekushandura, kwete panguva yekudzosera, saka funga kuti uchazofanirwa kuisa chero chinhu chisina kuwanikwa musource. AC-3 haina kunyatsoshanda nezvinodiwa nezuva rino uye haibvumirwe nebrowser, foni kana mamwe mawebhu maplayers pasina kudzokorora ku stereo.

Age pachayo hachisi chinhu — akawanda mafomati kubva kuti era ndivowo zvakanaka, zvakajeka nekuti zvese zvakanga makore makumi maviri kuti vaite navo. Chii chinokosha ndechokuti chii era akafungidzira: zvidiki mafaera, modest processors, hapana network, uye zvinhu munhu wese anofanira kusvika. Kwava vakafungidzirawo, format ndiro zvakanaka. Kwava havana, kuti ndiro chikonzero kuti kushandura.

Mabhurawuza anodecode afupi, akavimbika mafomu eaudio uye AC3 ari kunze kweiyo, saka faira inorodha pasi sezviri nyore kupfuura kutamba kana mutambi anotaura nyaya yematambudziko. Desktop software ine yakakura codec set inovhura pasina dambudziko. Kana audio inofanirwa kutamba pawebhusaiti, kushandura kwayo kunogona kugadziriswa - hapana mutambi wekuvaka achawedzera decoder iyo browser haisi kutumira.

Kuenzanisa chinangwa, kwete chikonzero. Kuti mutambire, 256 kusvika 320 kbps inoratidzika kune vese vanonzwa; kuti muite mashoko kana podcasts, 96 kusvika 128 kbps zvinokwana uye zvinovhara faira. Kunyora pasi pechikonzero chekunyora kunokuvadza nzvimbo — kunochengeta mashoko akapfuura nenzira yekuora uye hakudzosere chero chinhu chakatanga kunyorwa.

Codecs zvinoda kuiswa mumidziyo iyi zvinopihwa nemakambani ane kodzero dzezvigadzirwa zvemitambo, uye kupihwa kwazvo kunoitwa nevanhu vanotengesa decoders—foni, browser, uye operating system—nguva yakareba usati wawana faira. Izvi ndizvo zvinoita kuti maforodha aya arambe aripo muhardware uye kuti zvirongwa zvemahara zvekushandisa zvivepo, uye hazvina kuchinja chero chinhu panyaya yekushandura faira yawakawana.

Hapana kana iwe unokumbira kuti. Kushandura kunochengeta chikonzero chekukwira kwemitengo — 48 kHz inoramba iri 48 kHz, 44.1 kHz inoramba iri 44.1 kHz — nekuti kudzokorora kuongorora kunopa mutengo wemhando yemhando
