M4A → FLAC

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I M4A sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujika okuseleyo kwi FLAC engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi amakhulu kwaye ithetha ngokufanayo. Ihlala ihamba kakuhle phambi kohlela, kuba FLAC ayizukongeza udidi lwesibini lweeartefacts xa urhweba ngaphandle. I-FLAC ikunika ukuthembeka kwe-WAV kwisiqingatha sobungakanani, ngee-tags ze-metadata ezifanelekileyo kunye nomsebenzi womnatha ofakwe ngaphakathi, oko kukuthi, ilawula iilayibrari zengoma ezingalahlekiyo. M4A ifihla izinto ezimbini ezihlukileyo eziphambili kwesinye isiqalo — lossy AAC kunye lossless ALAC — kwaye i-Apple engasebenziyo hardware inkxaso ayihambelani.

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.

Ihlala ingasebenzi. M4A ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; FLAC ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi M4A. FLAC ihlala iphindaphindwa amaxesha amaninzi ngaphezu kwefayile elungileyo elahlekile, kwaye inkqubo yendalo yeApple yadibanisa kuphela inkxaso ngoku kwaye ngokungxamisekileyo.

Okumiselweyo yi 192 kbps ye-lossy FLAC; igqityiwe-kwi-lossless FLAC. Nciphisa kwi 320 kbps ye-audiophile okanye 96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa; ngaphantsi kwe-96 kbps i-lossy artifacts ibonakala kwingoma.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi M4A isiqulathi seefayili kwaye ibhalwe kwi FLAC isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-FLAC yi-Free Lossless Audio Codec, ifomati evulekileyo ukusukela ngo-2001 ecinezela ngaphandle kokususa isampuli enye.

Ewe - susa isiqulathi seefayili se M4A ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ngokungagqibekanga ewe — 48 kHz M4A ihlala i-48 kHz kwi FLAC. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi FLAC, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kudityaniswa iingoma ezilawulwa kumanqanaba ahlukeneyo.

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyiku-iPods ezidala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esithe nkqo sikhetha i-FLAC codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo.

Ewe — iifayile ezilayishwe phezulu M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.
