AMR ukuba WMA Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili AMR kwaye umguquli ukhetha WMA i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless WMA (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy WMA (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum. I-WMA ilahlekile ngokumiselweyo, kwi-ASF equlethe, eneempawu ezingalahlekiyo kunye nelizwi elilungelelanisiweyo elihlala lichaphazela.

Ingaba ukutshintsha AMR 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.

Ndingayiphawula i WMA ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AMR, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. WMA ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-WMA icinezelwe kakuhle kune-MP3 encoders yexesha elidlulileyo kwaye ihlala ifundeka ngu-Windows Media Player kunye nee-PlaysForSure ngaphambili.

Ingaba i WMA iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ihlala ingasebenzi. AMR 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 AMR. WMA ayixhaswanga phantse naphi na ngaphandle Windows, kwaye WMA older iifayili zingathabatha DRM ethintela uguqulo ngokupheleleyo.

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-WMA ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko WMA; dlula-kwi-lossless WMA. 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.

Ingaba ukuya ukusuka kwi AMR ukuya kwi WMA kuya kunciphisa ubunjani besandi sam?

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

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi AMR isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi WMA 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-WMA yiWindows Media Audio, iMicrosoft's answer to MP3, yasungulwa ngo-1999 kwaye yadityaniswa neWindows nganye efakwe kulo nyaka.

Ndingaguqula izigidi zeefayili AMR zibe WMA?

Ewe - susa isiqulathi seefayili se AMR 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.

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

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

Ndingazilungisa njani ilizwi kwinyathelo AMR ukuya kwi WMA?

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

Ingaba i-WMA iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

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-WMA codec ekhuselekileyo ye-platform ocacisayo.

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.

WMA

I-WMA (iWindows Media Audio) yifomathi yocinezelo lomsindo eyenziwe nguMicrosoft. Isetyenziswa ngokuqhelekileyo ukusasaza kunye neenkonzo zomculo kwi-intanethi.
