AMR ukuba Opus Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AMR yesandi kwi-Opus ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile AMR kwaye umguquli ukhetha i Opus codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko Opus (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko Opus (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe ezininzi. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum. Opus ilinganisela ukusuka kwi 6 kbps mono ukuthetha ukuya kwi 510 kbps stereo iingoma kwi bitstream efanayo kwaye itshintshe iimo ngokuzenzekelayo.

Ingaba ukutshintsha AMR ukuya ku Opus kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i Opus encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i Opus ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Ndingayiphawula i Opus ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AMR, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. Opus ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-Opus yi-codec elungileyo edlalayo elahlekile kwi-bitrates ephantsi ngomda ocacileyo, kwaye inamandla amaphetshana elizwi le-WhatsApp, iDiscord ne-WebRTC.

Ingaba i Opus iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ihlala ingasebenzi. AMR ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; Opus ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi AMR. I-Opus ayixhaswa yihardware ekhululekileyo - qiniseka ukuba udlala isoftware kuphela, kwaye ulindele ukuba i-car stereos ayihoyi.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. I-AMR ibulala umculo: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

I-bitrate yefayili ephumayo Opus iza kusetyenziswa ntoni?

Okungagqibekanga ku 192 kbps kulahleko Opus; dlula- kwi-lossless Opus. Nciphisa ku 320 kbps ku audiophile okanye 96 kbps kulizwi / ipodcast. Ukhetho lurhweba ubungakanani befayile ngokuchasene nobuxoki obuvakalayo; ngaphantsi kwe 96 kbps ulahleko lwee-artefacts zibonakala kwingoma.

Ingaba ukudlula kwi AMR ukuya kwi Opus kuya kunyusa ubunjani besandi sam?

Ukuba AMR ilahlekile kwaye Opus ayilahleki (umzekelo MP3 → WAV), i Opus ayingcono kune AMR — awunakubuyisela ulwazi olusele lulahlekile. Ukuba AMR ayilahleki kwaye Opus ayilahleki, i Opus codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kuninzi lwezinto eziquletheyo.

Ingaba umguquli AMR ukuya ku Opus ugcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AMR isiqulathi seefayili kwaye ibhalwe kwi Opus isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV ayisebenzi. I-Opus yi-IETF eqhelekileyo ukusukela ngo-2012 edibanisa i-Skype's SILK speech codec ne-Xiph's CELT music codec kwi-design enye.

Ndingaguqula izigidi zeefayili AMR zibe Opus?

Ewe - shiya isiqulathi seefayili se AMR iifayile ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye kwaye akukho mda wobungakanani befayili nganye, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10 yemizuzu.

Ingaba i Opus iyagcina ixabiso lesampuli elifanayo njenge AMR?

Ngokungagqibekanga ewe — 48 kHz AMR ihlala 48 kHz kwi Opus. Ukuba ufuna ukunyusa uvavanyo ukuze ulungelelanise (96 kHz → 44.1 kHz ukukhuphela iCD), ukhetho lwesampulu-yesantya lusebenzisa uvavanyo oluphezulu lomgangatho kwindlela efanayo yokugqitha kokukhowuda.

Ndingazilungisa njani i-loudness xa ndiguqula AMR ukuya ku Opus?

Ewe - ukhetho lokwenza isantya sisebenze ngokuqhelekileyo lusebenzisa ITU-R BS.1770 / EBU R128 ukwenziwa sebenze ngokuqhelekileyo kwi Opus, lujolise kwi -14 LUFS (umgangatho wokudlulisa) okanye -16 LUFS (umgangatho wepodcast). Isetyenziswa xa kuqhutywa iingoma ezimasterwe kumanqanaba ahlukeneyo.

Ingaba i Opus yam iya kudlala kwi-car stereo, i-iPod, ne-Sonos?

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayisebenzi kwi-iPods edala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esikhupha i-codec Opus esilungele i-hardware yakho emiselweyo.

AMR

I-AMR yi-codec yokuthetha elungele ukurekhodwa kwelizwi kunye noqhagamshelwano lwefowuni, oko kukuthi, iingoma zengoma zidla ngokubi kuyo.

Opus

Opus yi-codec yesandi evulekileyo eyaziwayo ebetha i-MP3 ne-AAC kwi-bitrates ephantsi, ngenxa yoko unxibelelwano lwelizwi kunye nokudlulisa kusetyenziswa.
