Ihele M4A lisebenzisa i-bitrate enjani?

Iphutha 192 kbps ku M4A olahlekelwayo; dlula-nge- M4A 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 i-M4A izogcina isilinganiso esifanayo sesampula njenge-MP3?

Ngokuzenzakalela yebo (48 kHz MP3 → 48 kHz M4A). 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-MP3 kuya ku-M4A?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku M4A kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Yebo — amafayela alayishwe phezulu MP3 aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi.

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

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

Kungani ihele M4A likhulu / lihlanzekile kunalelo MP3?

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.
