M4A ukuba WAV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi kwi-WAV ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile M4A kwaye umguquli ukhetha i WAV codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko WAV (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko WAV (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe ezininzi. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo. I-WAV igcina i-PCM engacinezelwanga emnyama - yonke isampuli igcinwa ngokuchanekileyo, nakweyiphi na ubunzulu be-bit kunye nesantya sesampuli esithathwe.

Ingaba ukutshintsha i-M4A ukuya kwi-WAV kunyusa umgangatho wesandi?

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I M4A sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujika okuseleyo kwi WAV engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi amakhulu kwaye ithetha ngokufanayo. Ihlala ihamba kakuhle phambi kohlela, kuba WAV ayizukongeza udidi lwesibini lweeartefacts xa urhweba ngaphandle. I-WAV yifomati efanelekileyo yohlela, ulawulo nokugcina, kuba ingaphinde ikhowudiwe nanini na ngaphandle kokudibanisa iindidi. M4A ifihla izinto ezimbini ezihlukileyo ezisemva kwesinye isiqalo — i-AAC elahlekile kunye ne-ALAC engalahlekiyo — kwaye uxhaso lwehardware lwe-Apple olungahambelaniyo.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albham iya kuqhubeka iphila kwi M4A ukuya kwi WAV uguqulo?

Ayiqhelekanga. M4A ihambisa i-metadata efanelekileyo, kodwa WAV ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshelo, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i M4A njengekopi ephawulweyo, okanye uphinde uphawule emva koko ngesixhobo njenge Mp3tag okanye iMusicBrainz Picard. I-WAV inamandla amakhulu - malunga ne-10 MB ngemizuzu ye-stereo kwi CD elungileyo - kwaye i-classic format ine-4 GB ye-ceiling kwaye akukho ndawo ye tags efanelekileyo.

Kutheni ezinye zeefayili zam M4A azitshintshi?

DRM. Iqela elincinci le M4A iifayile zifihliweyo yindawo yokurhweba 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.

I-bitrate yefayili ephumayo WAV iza kusetyenziswa ntoni?

Okungagqibekanga ku 192 kbps kulahleko WAV; dlula- kwi-lossless WAV. Nciphisa ku 320 kbps ku audiophile okanye 96 kbps kulizwi / ipodcast. Ukhetho lurhweba ubungakanani befayile ngokuchasene nobuxoki obuvakalayo; ngaphantsi kwe 96 kbps ulahleko lwee-artefacts zibonakala kwingoma.

Ingaba ukudlula kwi M4A ukuya kwi WAV kuya kunyusa ubunjani besandi sam?

Ukuba M4A ilahlekile kwaye WAV ayilahleki (umzekelo MP3 → WAV), i WAV ayingcono kune M4A — awunakubuyisela ulwazi olusele lulahlekile. Ukuba M4A ayilahleki kwaye WAV ayilahleki, i WAV codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kuninzi lwezinto eziquletheyo.

Ingaba umguquli M4A ukuya ku WAV ugcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi M4A isiqulathi seefayili kwaye ibhalwe kwi WAV isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV ayisebenzi. I-WAV yiMicrosoft ne-IBM RIFF-based audio container ukusukela ngo-1991, kwaye yiyo into eninzi yonke i-audio interface ne-DAW ibhala kwirecord.

Ndingaguqula izigidi zeefayili M4A zibe WAV?

Ewe - shiya isiqulathi seefayili se M4A iifayile ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye kwaye akukho mda wobungakanani befayili nganye, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10 yemizuzu.

Ingaba i WAV iyagcina ixabiso lesampuli elifanayo njenge M4A?

Ngokungagqibekanga ewe — 48 kHz M4A ihlala 48 kHz kwi WAV. Ukuba ufuna ukunyusa uvavanyo ukuze ulungelelanise (96 kHz → 44.1 kHz ukukhuphela iCD), ukhetho lwesampulu-yesantya lusebenzisa uvavanyo oluphezulu lomgangatho kwindlela efanayo yokugqitha kokukhowuda.

Ndingazilungisa njani i-loudness xa ndiguqula M4A ukuya ku WAV?

Ewe - ukhetho lokwenza isantya sisebenze ngokuqhelekileyo lusebenzisa ITU-R BS.1770 / EBU R128 ukwenziwa sebenze ngokuqhelekileyo kwi WAV, lujolise kwi -14 LUFS (umgangatho wokudlulisa) okanye -16 LUFS (umgangatho wepodcast). Isetyenziswa xa kuqhutywa iingoma ezimasterwe kumanqanaba ahlukeneyo.

Ingaba i WAV yam iya kudlala kwi-car stereo, i-iPod, ne-Sonos?

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayisebenzi kwi-iPods edala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esikhupha i-codec WAV esilungele i-hardware yakho emiselweyo.

Ingaba i-M4A yam ifayile ifihlakeleyo ngexesha liguqulwa kwi-WAV?

Ewe — iifayili ezilayishwe phezulu M4A ziqhubekeka kubasebenzi abamiselweyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sinikezele kwizinto eziqulethe isandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

M4A

I-M4A igcina i-AAC yesandi kwi-MP4 equlethe i-iTunes ne-Apple Music isebenzisa iingoma ezilayishwe ezantsi.

WAV

Iifayile ze-WAV zigcina isandi kwifomathi engacinezelwanga, nto leyo enika isandi esisemgangathweni we-CD esifanelekileyo kumsebenzi wesandi wobuchwephesha.
