I-lossy M4A ikhowudiwe kwi-192 kbps ngokumiselweyo. Isicwangciso Somgangatho Wesandi sinika 320 kbps kumgangatho olungileyo kunye ne-128 kbps kwifayili encinci. I-lossless M4A (WAV, FLAC) i ignores the bitrate and keeps every sample.

Ingaba ukutshintsha MP3 ukuya ku M4A kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i M4A encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i M4A ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo.

Ndingaguqula izigidi zeefayili MP3 zibe M4A?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

Ingaba i M4A iyagcina ixabiso lesampuli elifanayo njenge MP3?

Ngokungagqibekanga ewe — 48 kHz MP3 ihlala 48 kHz kwi M4A. 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 MP3 ukuya ku M4A?

Ayiluphi olu hlobo lwendlela. Umguquli awunakucwangcisa ubukhulu besandi kwaye ushiya umphakamo njengonjalo. Ukulinganisa umphakamo, qhuba i M4A egqityiweyo ngesixhobo Sokugqiba esikwindawo.

MP3 idlala phantse naphi na. I-AAC idlala kwizixhobo ze-Apple, ezininzi iifowuni ze-Android kunye ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyikubakho kwi-iPods ezidala, kwaye i-WAV idlala phantse nantoni na kodwa iyenza iifayile ezinkulu. Akukho zixhobo ezimiselweyo ezingaphambili kule phepha, ngoko khetha ifomati emiselweyo yomdlali wakho oxhasayo.

M4A ifihla izinto ezimbini ezihlukileyo ezisemva kwesinye isiqalo — i-AAC elahlekile kunye ne-ALAC engalahlekiyo — kwaye uxhaso lwehardware lwe-Apple olungahambelaniyo.

Ingaba i-MP3 yam ifayile ifihlakeleyo ngexesha liguqulwa kwi-M4A?

Ewe. Iifayile ezilayishwe phezulu ze MP3 ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga.
