AMR ukuba Opus Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AMR yesandi ibe yi-Opus ngaphandle kokulahleka komgangatho?

Layisha phezulu ifayili AMR kwaye umguquli wethu ukhetha Opus i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (Opus = WAV / FLAC / ALAC) sigcina yonke isampuli; isiphelo esilahliweyo (Opus = MP3 / AAC / OGG) simiselwe kwi-192 kbps ebonisa iincwadi zelizwi ezithethayo kunye nemidlalo emininzi.

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. 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.

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-Opus ifayili isebenzisa i-bitrate enjani?

Okumiselweyo yi-192 kbps ye-lossy Opus; igqityiwe-kwi-lossless Opus. Nciphisa kwi-320 kbps ye-audiophile okanye 64-96 kbps ye-audiobooks yegama elithethayo (elibonisa ngaphaya lelizwi, liphelisa ubungakanani befayili).

Ingaba ukutshintsha ukusuka ku AMR ukuya ku Opus kuya kunyusa ubunjani besandi sam?

Ukuba AMR ilahlekile kwaye Opus ayilahleki (umzekelo MP3 → WAV), ifayili Opus ayingcono kune AMR — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba AMR ayilahleki kwaye Opus ilahlekile, lindele ukuba i-Opus codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

Ingaba i-AMR ukuya kwi-Opus igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, kunye nabaphawuli besiqendu (ababalulekileyo kwiincwadi zesandi) bafundwa ukusuka kwi AMR kwaye babhalwe kwi Opus isiqulathi seefayili apho i-Opus ifomati ixhasa ii-tags. Ukwakhiwa kwencwadi yesandi ye-M4B ijikeleza-jikeleza kwi-M4B ne-AAX → i-M4B i-output.

Ndingaguqula izigidi zeefayili AMR zibe Opus?

Ewe - susa isiqulathi seefayili se AMR ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ingaba i-Opus iya kugcina inqanaba lesampuli elifanayo njenge-AMR?

Ngokungagqibekanga ewe (48 kHz AMR → 48 kHz Opus). Ukuba ufuna ukunyusa isampulu ukuhambelana (umzekelo. 96 kHz → 44.1 kHz yokushicilela i-CD) ukhetho lwesampulu-yexabiso eliphambili yenza oku ngesampulu ephezulu yomgangatho.

Ndingazilungisa njani ilizwi kwinyathelo AMR ukuya kwi Opus?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye Opus, ibeka i- -14 LUFS (isiqhelo sokusasaza), -16 LUFS (isiqhelo sepodcast), okanye -23 LUFS (isiqhelo sencwadi enesandi). Isetyenziswa xa kuguqulwa iingoma ngemiphakamo emininzi yolawulo.

Ingaba i-Opus iyadlala kwi-iPod / i-app yencwadi enesandi?

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, isebenza kakuhle kwi-iPods edala. Iincwadi zesandi ze-M4B zidlala ngesahluko sokuhamba kwi-iOS Books, i-Audiobookshelf, kunye ne-Smart Audiobook Player. Iinketho eziphambili ziquka i-preset yesixhobo.

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.
