AAC kuya AC3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-AAC kuya ku-AC3 umguquli womsindo?

It re-encodes a AAC audio file as AC3. Sample rate and channel count are preserved; the difference is the codec and container.

Ingabe isilinganiso sesampula kanye nesimo sesixhumi sigcinwa?

Ngephutha yebo — i-stereo ihlala i-stereo, isilinganiso sesampula sakuqala (44.1 kHz, 48 kHz, njll.) sithunyelwe ku-AC3 output.

Ingabe AAC kuya ku AC3 ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-AC3 emuva ku-AAC kule site. Uma ifomethi eyodwa ilahlekile, i-round-trip ayilungile noma ngabe ibukeka noma izwakala ifana.

Yini ikhwalithi yesipiliyoni okufanele ngilinde kusuka ku-AAC kuya ku-AC3?

Izilungiselelo ezizenzakalelayo zidinga ukusakazwa / ukhwalithi ye-web — ngokubona kufana nomthombo weningi labasebenzisi. Ukusetshenziswa kwegobolondo, khetha ukhetho lwekhwalithi ephezulu kuzinhlelo zokushintsha.

Ingabe ukushintsha AAC kuya ku AC3 kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i AC3 encoder isebenza kusuka kumsindo osele udlulele esinye isikhala se-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une master engalahlekelwa yilutho, ukukopisha i AC3 kusuka lapho kunciphisa isikhala esimibili ngokuphelele. I-AAC ilahlekelwa yizinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design. AC-3 yisandi esingenalutho esingena-channel, sivame u-5.1 ku-384 noma ku-448 kbps, ne-metadata yokuxoxa nokuhlanganiswa ngezansi.

Ingabe izihloko zesikhashana sami kanye nesithombe se-albhamu sizohlala isikhathi eside uma siguqulwa AAC kuya ku AC3?

Akunalutho. AAC ifaka i-metadata efanele, kodwa AC3 ayinaso isikhala esijwayelekile somuntu oculi, i-albhamu, inani le-track noma umhlobiso we-cover, ngakho-ke amathegi asuswa ngaphandle kokulahleka. Gcina i-AAC njengekhophi elabelwe, noma uphinde ubeke i-tag ngemuva ngethuluzi njenge Mp3tag noma MusicBrainz Picard. AC-3 ayisebenzi kahle ngokuya ngemigomo yamanje futhi ayivunyelwe yiziphequluli, amafoni noma abadlali abaningi be-web ngaphandle kokuxhuma phezulu kwe-stereo.

Yini okushoyo ihele AC3?

Ukuhamba okuncane kwefremu yomsindo okhonjiswanga ngaphandle kwebhokisi elijikelezayo. Lokhu kusho ukuthi amafayela amabili AC3 angaxhunywa ngokulula ngokubeka elinye ngemuva kwelinye, futhi ngokufanayo kusho ukuthi konke okungaphezu komsindo - ubude, ukufuna isibalo, ukuhoxa umdwebo - kufanele kufakwe ibhodlela njengenhlanganiso ngaphezu kokuyingxenye yefomethi, ngakho umdlali kufanele afunde ihele lonke ukuze asebenze ukuthi lide kangakanani. Kulokhu, into elula kakhulu ebizwa ngokuthi ihele lomsindo, okuwukuthi kungani livela ngaphakathi kwezinye izibhokisi ngaphezu kokuvela ngokwalo.

Kungani ifoni yami noma ithebhulethi irekhoda ku AAC?

Ngenxa yokuthi yilokho okukhiqizwa yi-hardware encoder kwidivayisi. Amamemo omsindo, ukurekhodwa kwesikrini kanye ne-audio track yenoma yini efilmwe kwifoni iphuma njenge AAC ngaphandle komuntu okhetha lokhu, ngakho-ke amafayela amaningi afika kulo futhi kungani ukhwalithi ingcono kunesayizi yefayela ebonisa. Akukho lutho oluzomisa ukuguquka; kusho ukuthi umsuka ukhonjiswa kathathu, yi-chip elungele impilo yebhethri ngaphezu kokungafani. I-AAC iyi-Advanced Audio Coding, ejwayelekile ngo-1997 njenge-MPEG-2 Part 7 futhi ifakwe ngokucacile ukushintsha i-MP3.

Ingabe kunelayisense exhunywe ku AAC?

Akuna omunye ongacabanga ngawo. I-codec ifakwe iziqukathi zepatenti, futhi ilayisense ibekwe ngumuntu othumela umbhalo oguquliwe — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ifayela lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware, futhi kungani izinketho ezingenazo i-royalty zikhiwa. Akunalutho olushintshayo mayelana nokushintsha ifayela olizithola, futhi kuyimibuzo ephilayo uma uthumela umbhalo oguquliwe wena.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-AAC ibe yi-AC3?

Ukuthunyelwa okungaziwa kuvunyelwe ngokuzenzakalela; ama-akhawunti abhalisiwe amahhala athola umkhawulo ophezulu, futhi ama-akhawunti we-Pro angeke abe ne-limit yefayela ngalinye. Umlando wesiphequluli uvame ukuba ngumkhawulo osebenzayo ngaphambi kokuba umkhawulo wethu we-server-side uqale.

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-AAC elilodwa libe yi-AC3?

Yebo. Thola noma khetha amafayela amaningi we-AAC ku-upload eyodwa — umguquli usebenza ngazo ngokufanayo futhi ubuyisela i-ZIP yemiphumela ye-AC3. Akunasidingo sokuphinda isikhashana sokufaka ihele ngalinye.

Yini ezoba namafayela ami AAC ngemuva kokuguqulwa?

Amafayela alayishiwe kanye ne-AC3 outputs zisuswa ngokuzenzakalela ngemuva kwefasitela lokugcinwa okuncane. Asihlolanga, asihlukanisi, noma siqeqeshe amafayela womsebenzisi. Ama-download links aqondile angaphansi kwesikhathi esilinganiselwe futhi axhunywe kwinhlanganiso yakho.
