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 zigqityiwe kwi-100 MB kwifayile nganye, kwaye WAV iqhuba ukuya kwi-10 MB ngomzuzu kwi stereo kuba akukho nto ingqutywe ngayo - isampuli nganye igcinwa kubukhulu obupheleleyo. Iimizuzu elishumi sele ikwinqanaba lokungena. 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.

Okumiselweyo 192 kbps kulahleko Opus; dlula-kwi-lossless Opus. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ukuba WAV ilahlekile (MP3, AAC) kwaye Opus ayilahleki (WAV, FLAC), i Opus ayingcono kune WAV — awunakubuyisela ulwazi olusele lulahlekile yi-WAV codec. Ukuba i WAV ayilahleki kwaye Opus iyalahleka, lindele ukuba i Opus encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi WAV isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi Opus isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. 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 - susa isiqulathi seefayili se WAV kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

Ngokungagqibekanga ewe (a 48 kHz WAV ivelisa 48 kHz Opus, a 44.1 kHz WAV ivelisa 44.1 kHz Opus). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz Opus yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz Opus — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye Opus, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-Opus yoluhlu lokudlala.

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-Opus codec ekhuselekileyo ye-platform ocacisayo.
