M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili yesandi ye-M4A?

I-M4A yifomati yesandi engekhoyo. I-encoder isusa iindidi ezingathethiweyo kunye neesandi ezifihlakeleyo ukuze zifike kubungakanani befayili obumalunga neshumi le-elinganayo engacinezelwanga. Ukubuyisela u-encoding i-M4A kwifomati enye engekhoyo kwenza ukuba umgangatho ulahleke; uguqule ukusuka kwi-master engasebenziyo xa kunokwenzeka. I-M4A yifomati yesandi ye-Apple ye-class yokuqala kwaye imiselwe ii-apps ezininzi ze-iOS kubandakanya iVoice Memos ne-Music app.

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 engaziwayo kuninzi lwaba 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 le nto ifowuni yam igcina konke njenge M4A?

Kuba isixhobo sefowuni sikhowudisa nantoni na eyenza ichip yayo kwihardware, kwaye M4A yiyo loo silicon yakhiwa kuyo. Inkqubo yekhamera ayifuni umbuzo - ibhala ifomati yesixhobo esikwaziyo ukuvelisa kwinqanaba le-frame epheleleyo ngaphandle kobushushu. Ukutshintsha emva koko kuqhelekileyo kwaye akubiza nto kwixabiso ukuba ukhetha injongo egcina umthwalo ofanayo. I-M4A yi-MP4 equlethe i-audio kuphela, kwaye yiyo into eyenza i-iTunes, i-Apple Music kunye ne-iPhone Voice Memos app.

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 kuqokelela zonke iziqhagamshelanisi, 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 yokubuyisa. 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 kwenziwa 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 ofundayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukukhowuda ngaphezulu komthombo we bitrate kusezantsi kwesithuba - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba i-M4A ilahlekile okanye ayilahleki?

I-M4A ilahlekile — i-encoder isusa i-data i-encoder igqiba ukuba ayithethi ukuba ifike kubungakanani befayili encinci. M4A ifihla izinto ezimbini ezihlukileyo ezisemva kwesinye isiqalo — i-AAC elahlekile kunye ne-ALAC engalahlekiyo — kwaye uxhaso lwehardware lwe-Apple olungahambelaniyo.

Yintoni endingayenza ukuba ndiguqule i-M4A ibe yi-MP3?

Ukwabelana nge-imeyili kunye nemidiya yoluntu, guqula i-M4A ibe yi-MP3 — ukudlala okubanzi kunye nobungakanani befayili encinci. Ukwabelana ngokuthembekileyo nabalandeli besandi, guqula ibe yi-FLAC okanye i-WAV ukugcina ubunjani obuqhelekileyo.
