M4R ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4R yesandi ibe yi-MP3 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili M4R kwaye umguquli ukhetha i MP3 codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko MP3 (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko MP3 (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. Umthwalo osebenzayo yi-AAC, i-conventional caped kwimizuzu engama-40, eyona nto ide i-iOS iyamkele. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ingaba ukutshintsha M4R ukuya ku MP3 kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP3 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 MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

I-MP3 ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy MP3; igqityiwe-kwi-lossless MP3. 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.

Ingaba ukutshintsha ukusuka ku M4R ukuya ku MP3 kuya kunyusa ubunjani besandi sam?

Ukuba M4R ilahlekile kwaye MP3 ayilahleki (umzekelo MP3 → WAV), i MP3 ayingcono kune M4R — awunakubuyisela ulwazi olusele lulahlekile. Ukuba M4R ayilahleki kwaye MP3 ilahlekile, i MP3 codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Ingaba i-M4R ukuya kwi-MP3 igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi M4R isiqulathi seefayili kwaye ibhalwe kwi MP3 isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ndingaguqula izigidi zeefayili M4R zibe MP3?

Ewe - susa isiqulathi seefayili se M4R 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.

Ingaba i-MP3 iya kugcina inqanaba lesampuli elifanayo njenge-M4R?

Ngokungagqibekanga ewe — 48 kHz M4R ihlala i-48 kHz kwi MP3. 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.

Ndingazilungisa njani i-loudness xa ndiguqula i-M4R ibe yi-MP3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi MP3, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast).

MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

Ingaba ifayili yam M4R ifihlakeleyo ngexesha lokuguqulwa ukuya kwi MP3?

Ewe — iifayile ezilayishwe phezulu M4R ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

Ithatha ixesha elingakanani ukutshintsha i-M4R yeyure enye ibe yi-MP3?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uvule ukhetho lokumisela ngokuqhelekileyo. Ukuba ubona utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya inokuba isebenzisa iReplayGain okanye ulawulo oluqhelekileyo lwe-track nganye kukudlala — hayi kuthi. Sukwenza oko ukuze uzive amanqanaba asemthethweni MP3.

M4R

I-M4R yifomati yefayile esetyenziselwa iithowuni ze-iPhone. Ngokwenyani yifayile yeaudio yeAAC enolwandiso olwahlukileyo.

MP3

Iifayile zeMP3 zisebenzisa ucinezelo olulahlekileyo ukunciphisa ubungakanani befayile ngelixa zigcina umgangatho wesandi owamkelekileyo kubaphulaphuli abaninzi.
