WAV → Opus

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. WAV igcina yonke imilinganiselo ngokuchanekileyo; Opus isusa into eyenza imodeli ye psychoacoustic ilindele ukuba awuzukuyiva. Kwi 192 kbps nangaphezulu loo lindeleko kulungile ngokwaneleyo ukuba icacile kwizinto ezininzi nezixhobo ezininzi. Gcina i WAV njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi Opus.

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WAV, 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.

Ihlala ingasebenzi. WAV 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 WAV. I-Opus ayixhaswa yihardware ekhululekileyo - qiniseka ukuba udlala isoftware kuphela, kwaye ulindele ukuba i-car stereos ayihoyi.

Ii-akhawunti ezikhululekileyo zigqitha kwi-100 MB kwifayili nganye, kwaye WAV iqhuba ukuya kwi-10 MB ngomzuzu kwi-stereo kuba akukho nto malunga nayo icinezelwe - isampuli nganye igcinwa kubukhulu obupheleleyo. Iimizuzu elishumi sele zikwinqanaba. I-Premium iphakamisa i-cap ngokucacileyo, kwaye ifomati ine-4 GB ye-cage yayo ngaphezulu kwayo, nto leyo eyenza ukuba iintlanganiso ezide zifike zihlukaniswe zibe ziinkalo ezilinganisayo; ulayishe nganye nganye kwaye zithathwe njengemisebenzi enye. I-WAV inamandla amakhulu - malunga ne-10 MB ngemizuzu ye-stereo kwi CD elungileyo - kwaye i-classic format ine-4 GB ye-ceiling kwaye akukho ndawo ye tags efanelekileyo.

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.

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

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi WAV 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.

Ewe - shiya isiqulathi seefayili se WAV 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.

Ngokungagqibekanga ewe — 48 kHz WAV 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.

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.

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.
