M4A ukuba AC3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ingaba ukuguqulwa kwe-M4A ukuya kwi-AC3 kunokuphinda kuphindeke?

Ungaguqula i-AC3 kwakhona kwi-M4A kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Yintoni umgangatho wemveliso endingalindele ukuba ndiyilindele ukusuka kwi-M4A ukuya kwi-AC3?

Izicwangciso ezimiselweyo zijolise kwi-broadcast / umgangatho we-web - ngokubonakalayo ifana nomcebo kubabukeli abaninzi. Ukusetyenziswa kovimba, khetha ukhetho oluphezulu lomgangatho kwimimiselo yoguquli.

Ingaba ukutshintsha M4A ukuya AC3 kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AC3 encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu impumelelo ihlala icacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AC3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala siyi-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albhamu iya kuqhubeka i M4A ukuya ku AC3 uguqulelo?

Ayiqhelekanga. M4A ihambisa i-metadata efanelekileyo, kodwa AC3 ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshi, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i M4A njengekopi ephawulweyo, okanye uphinde uphawule emva kwesixhobo njenge Mp3tag okanye i MusicBrainz Picard. AC-3 ayisebenzi kakuhle ngemigangatho yangoku kwaye ayivunyelwanga ziibrowser, iifowuni okanye abadlali abaninzi bewebhu ngaphandle kokudibanisa phantsi kwistereo.

Yintoni na i-AC3 ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini AC3 zingadityaniswa ngokulula ngokubeka enye emva kwenye, kwaye ngokufanayo kutheni konke okungaphezulu kwesandi - ubude, ukukhangela isalathisi, ubugcisa bokuqubha - kufuneka kuboshwe njenge konvensi kunokuba ibe yinxalenye yefomati, ngoko umdlali kufuneka ufunde ifayile yonke usebenze ukuba ide kangakanani. Kumalunga nento elula ebizwa ngokuba yifayile yesandi, eyiyo isizathu sokuba ivela ngaphakathi kwezinye iziqulathi-zifayili rhoqo kuneyo.

Kutheni le nto ifowuni yam okanye i-tablet irekhoda kwi M4A?

Kuba yiyo loo nto i-hardware encoder kwisixhobo ivelisa. Ii-memos zelizwi, ukurekhodwa kwesikrini kunye nokulandela umkhondo wesandi wento erekhodwe kwifowuni ziphuma njenge M4A ngaphandle kokuba umntu ukhetha, oko kukuthi kutheni iifayile ezininzi zifika kuyo kwaye kutheni umgangatho uhlala ungcono kune-ubungakanani befayili ebonisa. Akukho nto malunga nayo imisa ukutshintsha; oku kuthetha kuphela ukuba umthombo wakhowudiwe kabini, yi-chip elungele ukuphila kwebhetri kunokuba kuthembekile. I-M4A yi-MP4 equlethe i-audio kuphela, kwaye yiyo into eyenza i-iTunes, i-Apple Music kunye ne-iPhone Voice Memos app.

Kutheni ezinye zeefayili zam M4A zingaguqulwa?

DRM. Iqela elincinci le M4A iifayile zifihliweyo yindawo yokuthenga 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 kukho ilayisensi edityaniswe ne M4A?

Akukho nto ofuna ukuyicinga. I-codec iquka i-patent pools, kwaye ilayisensi ibekwe ngumthumeli we-decoder - ifowuni, umkhangeli zincwadi, inkqubo yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke indawo kwihardware, kwaye kutheni i royalty- free alternatives yakhiwa naphi na. Ayitshintshanga nto malunga nokutshintsha ifayile oyinayo, kwaye kumbuzo ophilayo kuphela ukuba uthumeli i-encoder ngokwakho.

Ingaba kukho umda wobungakanani befayili xa uguqula i-M4A ibe yi-AC3?

Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.

Ndingaguqula iifayili ezininzi ze-M4A zibe yi-AC3 ngaxeshanye?

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

Ithini into eyenza ukuba i-M4A yam ifile iguqulwe?

Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

Ziziphi iinkqubo ezikwaziyo ukudlala ifayili ye AC3?

AC3 idlala kumaqela amaninzi emidlalo, kwii-browser, kunye neelayibrari zemidiya. I-iTunes / i-Apple Music, i-VLC, i-Foobar2000, kunye neenkqubo zemidiya yefowuni ziphatha ngokuzimeleyo.
