M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili M4A?

M4A is an audio-only MPEG-4 container format, often used for AAC-encoded audio.

Ingaba umgangatho sele ulahlekile kwifayili M4A?

Into na leyo ikhowudi yokuqala yagqiba ukuyisusa, ayikwazi ukubuyiselwa. M4A icindezela ngokuyila into ethe indlebe ayizukuyiqaphela - iingoma ezimdaka ezihlala phantsi kwezi zikhulu, ukuphindaphinda kumazantsi okuva - kwaye isuse ngokusisigxina. Kwi bitrate elungileyo engayikuva ngaphaya kwabanye bonke. Into engayiyo ibuyiselwa, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele eyakuqala. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo.

Kutheni isandi sihlala sivale kwifowuni yam M4A?

Kuba isixhobo sefowuni sikhowudi nge chip kunokuba sikhowudi nge processor, kwaye le yifomati eyenziwe yi silicon. Iincoko, iividiyo, iividiyo kunye nokuthumela imiyalezo iimilo zonke ziphuma kwikhowudi enye, nto leyo eyenza ukuba banikezele kwifomati engasebenziyo nento oyenzayo. Idlala kwi Apple hardware ngaphandle kocinga kwaye ifuna ukutshintshela kakhulu rhoqo naphi na.

Ingaba umculi, i-albhamu kunye nomfanekiso wesiqulathi seefayili kwi M4A yam uhlala uguqulwa?

Ziyenza apho ifomati yenjongo ikhona indawo yokuzibeka. M4A ithatha iimpawu kunye nomsebenzi womzobi ofakwe ngaphakathi njengenxalenye yefayile, kwaye uguqulelo lukopa ngaphezulu kwendawo nganye eqondayo indawo engqongileyo. Iimpawu ezingaqhotyoshwanga ziyimfuneko - zacaciswa phambi kokuba uphawulo lube lulindeleko oluqhelekileyo kwaye zigcine akukho nto, ngoko ithala leencwadi eliguqulelwe ngendlela lifika njengedonga lweengoma ezingabonakaliyo.

Ingaba i-M4A ifayili iyakwazi ukuthwala i-5.1 surround mix?

Ewe - ifomati iphatha ngaphezulu kweendawo ezimbini zesandi ngokuchanekileyo, ngoko ke uthelekiso olujikelezayo lugcina ubeko lwesandi saso kunokuba luyihlole kwi-stereo kwindlela engaphakathi. Ukuba uthetha ngayo njenge-stereo ixhomekeke kwisiphelo eside: umfumani uya kucoda zonke iindawo zesandi, ifowuni iya kuhlambulula ngexesha lokudlala ngaphandle kokungakhathali. Ukutshintsha kwifomati ye-stereo kuphela yenza ukuba uthelekiso luhlale.

Ingaba i-M4A iyadlala ngokuthe ngqo kwiphepha le-web?

Ewe. M4A iphakathi kwefomati zesandi ezimfutshane ezisuka kumkhangeli zincwadi, ngoko ke ingaqhutywa kwinxalenye yesandi okanye kumdlali wepodcast kwaye isebenza kuwo onke amacala ngaphandle koplugin okanye ifayile yokubuyisela. Oku kwenza ukuba ibe yinjongo yoshicilelo olukhuselekileyo, kwaye yiyo loo nto ukuguqula ushicilelo olunobungozi kule fomati kuqhelekileyo indlela efutshane yokufumana idlala kwiwebhusayithi. I-M4A igcina i-data ye-meta eninzi ye-iTunes-style, izihloko kunye nomsebenzi womzobi okhuselekileyo, kwaye yifomati yesandi esemthethweni kwisixhobo se-Apple.

Ingaba ndifuna i-Mac ukuze ndisebenze neefayili M4A?

Ayinaku. Ifomati yaphuma kwi-Apple kwaye yiyo into eyenzayo izixhobo zayo kunye nesoftware ngokumiselweyo, kodwa iifayile zihlala ziqhelekileyo kwaye zifunda kakuhle naphi na ngesixhobo esifanelekileyo. Ukutshintsha apha kwenzeka kumncedisi, ngoko akukho kufakwa kwe-QuickTime, akukho zixhobo ze-Apple kwaye akukho bhokisi ye-platform-ekhethekileyo ye-codec ibandakanyiwe naphi na kwinkqubo.

Yintoni i-bitrate ekufuneka ndiyiguqule iifayile zam M4A?

Uthelekiso lwendawo ebekwe kuyo, hayi umthombo. Kwingoma, 256 ukuya 320 kbps icacile kuye wonke umntu ophulaphulayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukunxulumana ngaphezulu komthombo we bitrate kusezantsi kwesicwangciso - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba ukusebenzisa i M4A kudinga ilayisenisi yepateni?

Ayikuko kuwe. Ii codecs ezibandakanyiweyo ziquka iindidi zepateni, kwaye ilayisensi ibekwe ngabantu abathutha ii decoders - ifowuni, umkhangeli zincwadi, indlela yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke ihardware kwaye kutheni i royalty- free efana nayo ikhona, kwaye ayitshintshanga nto malunga nokuguqula ifayile oyinayo.

Ingaba ukutshintshela kutshintsha umyinge wesikhokelo sesandi sam M4A?

Ayinaku ukuba ungacela ukuba ikwenze. Uguqulelo lugcina umyinge wombhalo ophambili - 48 kHz uhlala 48 kHz, 44. 1 kHz uhlala 44. 1 kHz - kuba ukuphinda uthathe isampuli kubiza kakhulu umgangatho oncinci ngaphandle koncedo xa akukho nto ifunayo. Izixabiso ziyanele: ii CD zesandi zifuna 44. 1 kHz, abanye abadlali be hardware abadala bavuma akukho lunye, kwaye imibhobho yelizwi ifuna 16 kHz. Cwangcisa umyinge ngokucacileyo kwezi meko kwaye uyishiye ngaphandle.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i M4A?

Akukho nanye, kwaye ifanele ukuqonda kutheni: unikezelo luphawu, ngelixa i bytes ngaphakathi zidityaniswe kwifomati ekhethekileyo. Ukuphinda ubize ifayile ivelisa ifayile igama layo lithembisa into imixholo yayo ayinikezeli, kwaye nantoni na evula ifayile okanye ilahlekile ifayile okanye ifunda ngokungachanekanga. Ukuphela kwendlela efutshane kuhlobo olubini oluyinyani ibhokisi efanayo phantsi kwegama elahlukileyo - kwaye nalapho ukuphinda ubhale ngokuchanekileyo kukhuselekile kunegama elahlukileyo.

Ndingaguqula isiqulathi seefayili esipheleleyo se M4A iifayili ngenye indlela?

Nge akhawunti, ewe - shiya ngaphaya kunye kwaye zifolwa njengemisebenzi enye endaweni yokuphathwa enye ngexesha, ngemimiselo efanayo esetyenziswa kwiqela kunye neziphumo ezibuyiselweyo kunye. Uguqulelo oluzenzekelayo luqhuba ifayile enye ngexesha (izixhobo zokudibanisa zithatha ezimbini); inkqubo ehlawulweyo ivula uqhubekeko lweqela kunye nobukhulu befayile nganye umda, owenza uguqulelo lwefayile yonke yovimba isebenziseke.
