Indlela yokwenza ukuba i-Loudness isebenze ngokuqhelekileyo kwi-AAC

1 Layisha phezulu i AAC audio files ofuna ukuyifaka kwinqanaba elihambelanayo - iseti epheleleyo ngaxeshanye ilungile.

2 Khetha isiphelo: malunga ne -14 LUFS yezixhobo zokuqhuba, -16 LUFS yepodcasts, -23 LUFS yosasazo.

3 Sebenzisa uvavanyo; ubukhulu besandi kunye nenqanaba eliphezulu lilinganiselwa phambi kokuba nayiphi na inkxaso igqibwe.

4 Layisha ezantsi ifayili eqhelekileyo AAC, ngemiboniso engaphakathi kwengoma nganye eshiyekanga.

Yenza ukuba i-AAC isebenze FAQ

Nantoni na ekhethekileyo kwi AAC apha?

Ewe — I-AAC ithatha ulibaziso lwe-encoder kwisiqulathi seefayili, ngoko ukutywina okunobuchule kungashiya imizuzwana emininzi yoxolo ekufuneka i-trim efanelekileyo isuse. Kubalulekile ukwazi xa injongo isisigqibo esiqhubekayo kunokuba yifayili enye.

Ingaba ukuthe nkqo kucinezela i-dynamics?

Hayi. Kuyinto enye i inzuzo yocwangciso lwefayile yonke, ngoko ubudlelwane phakathi kweendawo ezimdaka nezo msindo akufuneki kuqhutywe. Uxinzelelo nokulinganisa ziinkqubo ezihlukileyo kwaye azisebenzi apha.

I Yenza ukuba i-AAC isebenze igqiba njani umphakamo olungileyo?

Ngokucacileyo, ubukhulu besandi bulinganiselwa ngokuchasene ne-EBU R128 standard kwaye ulungelelaniso oluthile lokufumana luzisa ifayili yonke kwi-LUFS emiselweyo - eyiyo into ethe yavavanywa ziinkqubo zokudlulisa, kwaye ayifani nento efana nokugqiba. Ifayili ivavanywa kuqala kwaye ukulungisa kulandele uvavanyo, kunokuba kusetyenziswe uncedo oluthe nkqo kwaye kulindeleke.

Yintoni i-differance phakathi koku nokuzibeka phezulu nje?

Utshintsho lomqulu lusebenzisa inani okhethayo. Ukwahlula ngokuqhelekileyo kulinganisela ukuba ifayile inamandla kangakanani na kwaye ibala unikezelo olufunekayo ukubetha injongo, ngoko iifayile ezilishumi ezirekhodiweyo kumanqanaba alishumi ahlukileyo zonke zifika kwinye enye.

Ingaba i Yenza ukuba i-AAC isebenze ibiza nantoni na?

No. Yenza ukuba i-AAC isebenze ikhululekile ngaphandle kwe-akhawunti kwaye idibanisa akukho phawu lwamanzi lwesandi okanye i-tag ethethayo kwimveliso. Ulayisho lwakho lususwa kubasebenzi kamva emva kokuba umsebenzi ugqityiwe.

Ingaba kukho umda wobungakanani befayili kwi Yenza ukuba i-AAC isebenze?

Ewe: i-akhawunti ekhululekileyo iqhubekeka umsindo ukuya kwi-200 MB ngefayile, ekwi-bitrates eqhelekileyo yiyure ezininzi zezinto; i-ffmpeg iyenza i-decoding ne-encoding, ngokuchanekileyo njengoko izakuba kwi-desktop. Lo ngumgangatho ophezulu kakhulu kwiwebhusayithi emva kwevidiyo, kwaye umsebenzi wesandi uhlala uhamba kuwo.

Ingaba iimpawu kunye nobugcisa besiqhoboshelo buhlala?

Ewe. ID3, Vorbis iingcamango ne MP4 metadata atoms zithunyelwe, ubugcisa begophe buqu, ngoko ifayile egqityiweyo ihlala ilungelelaniswe kakuhle kwithala leencwadi lengoma. Iimali ze ReplayGain ziphinda zibalolwe endaweni yokukopa, kuba enye egqityiweyo ingcono kunengayo.

Kutheni i MP3 inxuwa liququzelela Yenza ukuba i-AAC isebenze?

MP3.to ibekwe phantsi kwefomati eyenza umsindo ophathekayo oqhelekileyo: odlalayo jikelele, omncinci ngokwaneleyo ukulibaziseka, nolahlekelwe ngumsindo ngendlela ebalulekileyo kuphela ukuba ugcina ukuphinda ukhowudi. Uluhlu lwemisebenzi yesandi: umntu ofanayo ofuna ubungakanani obutshintshiweyo uhlala efuna ifayile yokutywina, ethe nkqo okanye eyenziwe incinane kwimeko efanayo. Ukubeka Yenza ukuba i-AAC isebenze ngasemva kokukhuphela okufanayo, icaps ezifanayo neakhawunti efanayo iguqula i-tabs ezintathu zibe enye.
