M4A ukuba WMA Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi ibe yi-WMA ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili M4A kwaye umguquli ukhetha i WMA codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko WMA (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko WMA (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo. I-WMA ilahlekile ngokumiselweyo, kwi-ASF equlethe, eneempawu ezingalahlekiyo kunye nelizwi elilungelelanisiweyo elihlala lichaphazela.

Ingaba ukutshintsha M4A ukuya ku WMA kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i WMA 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 WMA ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Kutheni ezinye zeefayili zam M4A azitshintshi?

DRM. Iqela elincinci le M4A iifayile zifihliweyo yindawo yokurhweba okanye isoftware ekhupheleyo, kwaye umsindo ofihliweyo awunakucinywa uphawu nganoma uphi umguquli. Nantoni na oyiyikhuphe ngokwakho, uyirekhode, okanye uyithengise ngaphandle kokhuselo iguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo. M4A ifihla izinto ezimbini ezihlukileyo eziphambili kwesinye isiqalo — lossy AAC kunye lossless ALAC — kwaye i-Apple engasebenziyo hardware inkxaso ayihambelani.

Ingaba i WMA iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ihlala ingasebenzi. M4A ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; WMA ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi M4A. WMA ayixhaswanga phantse naphi na ngaphandle Windows, kwaye WMA older iifayili zingathabatha DRM ethintela uguqulo ngokupheleleyo.

I-WMA ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy WMA; igqityiwe-kwi-lossless WMA. Nciphisa kwi 320 kbps ye-audiophile okanye 96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa; ngaphantsi kwe-96 kbps i-lossy artifacts ibonakala kwingoma.

Ingaba ukutshintsha ukusuka ku M4A ukuya ku WMA kuya kunyusa ubunjani besandi sam?

Ukuba M4A ilahlekile kwaye WMA ayilahleki (umzekelo MP3 → WAV), i WMA ayingcono kune M4A — awunakubuyisela ulwazi olusele lulahlekile. Ukuba M4A ayilahleki kwaye WMA ilahlekile, i WMA codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Ingaba i-M4A ukuya kwi-WMA igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi M4A isiqulathi seefayili kwaye ibhalwe kwi WMA isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-WMA yiWindows Media Audio, iMicrosoft's answer to MP3, yasungulwa ngo-1999 kwaye yadityaniswa neWindows nganye efakwe kulo nyaka.

Ndingaguqula izigidi zeefayili M4A zibe WMA?

Ewe - susa isiqulathi seefayili se M4A 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-WMA iya kugcina inqanaba lesampuli elifanayo njenge-M4A?

Ngokungagqibekanga ewe — 48 kHz M4A ihlala i-48 kHz kwi WMA. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ndingazilungisa njani i-loudness xa ndiguqula i-M4A ibe yi-WMA?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi WMA, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast).

Isixhobo esiphambili esimiselweyo esithe nkqo sikhetha i-WMA codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo. I-WMA icinezelwe kakuhle kune-MP3 encoders yexesha elidlulileyo kwaye ihlala ifundeka ngu-Windows Media Player kunye nee-PlaysForSure ngaphambili.

Ingaba ifayili yam M4A ifihlakeleyo ngexesha lokuguqulwa ukuya kwi WMA?

Ewe — iifayile ezilayishwe phezulu M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.
