AAC kuya Opus Imibuzo Evame Ukubuzwa Yokuguqulwa

Ingabe AAC kuya ku OPUS ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-OPUS 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-OPUS?

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 OPUS kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i OPUS 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 OPUS 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. I-Opus iqala ngokukhuluma kusuka ku-6 kbps mono speech kuya ku-510 kbps stereo music ku-bitstream efanayo futhi ishintsha indlela ngokuzenzakalela.

Yini okushoyo ihele OPUS?

Ibhokisi lemisindo ngaphakathi kwalo, hhayi i-audio ngokwayo. Lo mbhalo ongeziwe uhlala lapho ubude, umbiko wokufuna kanye nanoma yimiphi imininingwane ye-metadata ifomu lichaza khona, ngakho umdlali ungazi ukuthi i OPUS ihlala isikhathi esingakanani ngaphambi kokuqothula ifremu eyodwa endaweni yokuskena ihele lonke ukuze ufunde. Lokhu kusho futhi ukuthi ubukhulu abukwazi ukuxazulula okungaphakathi: amabhokisi amaningi anjalo avunyelwe ukuphatha okungaphezu kwehlobo elinye lomsindo, ngakho amafayela amabili OPUS angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle.

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 i-OPUS izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. AAC i-decoded yinoma yini, kufaka phakathi iyunithi yemoto kanye nabadlali abadala; OPUS idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku AAC. I-Opus ayixhaswa yi-hardware ehlukile - cabanga ukuthi isofthiwe idlala kuphela, futhi ulindele ukuthi i-stereo yemoto ingayihoyi.

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 OPUS ikhona futhi ikhona ngezinto ezidinga ukudlalwa ngazo?

Lokhu kuyingozi engokoqobo. OPUS iyi-codec emisha futhi iyingcono kunazo zonke ezidala kuleyo bitrate efanayo — ibonakala ngezansi kwe-96 kbps — kodwa "engcono" ayixhaswanga, futhi imoto encane, umdlali ohlala ehlukile noma i-TV evela ngaphambi kokuba ikhona ngeke ikwazi ukukwazisa ihele. Ama-browsers, amafoni namakhompyutha alungile. Khangela isisetshenziswa esidala esidinga ukudlala futhi ukhethe kuyo, hhayi kumanani.

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

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Yini ezoba namafayela ami AAC ngemuva kokuguqulwa?

Amafayela alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi ahlukaniswe. Ukufaka kanye nohele oluguqulwe kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukuphoqa okuphelele.
