Indlela yokuguqula M4A kuya MP3

Inyathelo 1: Ngenisa M4A amafayela usebenzisa inkinobho ngasentshonalanga noma ngoshicilela bese ushiya.

Inyathelo lesi-2: Chofoza inkinobho ethi 'Tshintsha' ukuqala ukuguqulwa.

Inyathelo 3: Qapha okuguqulwe MP3 amafayela

M4A kuya MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo M4A ube MP3 ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele M4A futhi umguquli wethu uzokhetha i MP3 codec / bitrate ukuhlanganisa okuhambisana nomsuka. Injongo engalahleki (MP3 = WAV / FLAC / ALAC) igcina yonke isampula; injongo elahlekile (MP3 = MP3 / AAC / OGG) iphutha liyi 192 kbps ecacile kumazwana amaningi.

Ihele MP3 lisebenzisa i-bitrate enjani?

Iphutha 192 kbps ku MP3 olahlekelwayo; dlula-nge- MP3 ongalahlekelwanga. Nciphisa ku 320 kbps ku-audiophile noma ku 96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku fidelity ezwakalayo ku bitrates ephansi kakhulu.

Ingabe ukusuka ku M4A kuya ku MP3 kuzonciphisa ubunjani bomsindo wami?

Uma M4A ilahlekelwa futhi MP3 ayilahleki (isibonelo MP3 → WAV), ihele MP3 alingcono kuna M4A — awukwazi ukubuyisela imininingwane esele ilahlekile. Uma M4A ilahlekelwa futhi MP3 ayilahleki, cabanga ukuthi i-MP3 codec izocindezela futhi; ku-192 kbps lokhu kucacile kunoma iyiphi ingxenye.

Yebo — susa isibaya se M4A amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ingabe i-MP3 izogcina isilinganiso esifanayo sesampula njenge-M4A?

Ngokuzenzakalela yebo (48 kHz M4A → 48 kHz MP3). Uma ufuna uku-downsample ukuhambisana (isibonelo 96 kHz → 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngekhwalithi ephezulu yoku-resamply.

Ingabe ngizolungisa umsindo ku-M4A kuya ku-MP3?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku MP3 kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe ihele lami M4A liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu M4A aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-M4A libe MP3?

I-codec efanayo iphinde i-mux: imizuzwana engu-10-30. Yenza kabusha i-codec ehlukile: ngokuvamile 10-20% yesikhathi somthombo, ngakho-ke ihora M4A → MP3 liphele ngemizuzu engu-6-12.

Kungani ihele MP3 likhulu / lihlanzekile kunalelo M4A?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule isinqumo sokujwayelekile. Uma ubona ushintsho lwezinga, umdlali wakho wesandi noma ithala lemithombo ingasebenzisa i-ReplayGain noma ukuguqulwa kwe-track-by-track ku-playback — hhayi nathi.

Ingabe ngiguqula M4A ukulayisha phezulu okuqhubekayo ku MP3?

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
