M4R ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4R yesandi kwi-MP3 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile M4R kwaye umguquli ukhetha i MP3 codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko MP3 (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko MP3 (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe 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-bitrate yefayili ephumayo MP3 iza kusetyenziswa ntoni?

Okungagqibekanga ku 192 kbps kulahleko MP3; dlula- kwi-lossless MP3. Nciphisa ku 320 kbps ku audiophile okanye 96 kbps kulizwi / ipodcast. Ukhetho lurhweba ubungakanani befayile ngokuchasene nobuxoki obuvakalayo; ngaphantsi kwe 96 kbps ulahleko lwee-artefacts zibonakala kwingoma.

Ingaba ukudlula kwi M4R ukuya kwi 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 ayilahleki, i MP3 codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kuninzi lwezinto eziquletheyo.

Ingaba umguquli M4R ukuya ku MP3 ugcina 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 amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV 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 - shiya isiqulathi seefayili se M4R iifayile ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye kwaye akukho mda wobungakanani befayili nganye, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10 yemizuzu.

Ingaba i MP3 iyagcina ixabiso lesampuli elifanayo njenge M4R?

Ngokungagqibekanga ewe — 48 kHz M4R ihlala 48 kHz kwi MP3. 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 M4R ukuya ku MP3?

Ewe - ukhetho lokwenza isantya sisebenze ngokuqhelekileyo lusebenzisa ITU-R BS.1770 / EBU R128 ukwenziwa sebenze ngokuqhelekileyo kwi MP3, lujolise kwi -14 LUFS (umgangatho wokudlulisa) okanye -16 LUFS (umgangatho wepodcast). Isetyenziswa xa kuqhutywa iingoma ezimasterwe kumanqanaba ahlukeneyo.

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

Ingaba i-M4R yam ifayile ifihlakeleyo ngexesha liguqulwa kwi-MP3?

Ewe — iifayili ezilayishwe phezulu M4R ziqhubekeka kubasebenzi abamiselweyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sinikezele kwizinto eziqulethe isandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

Sukwenza oku ukuze uzive i MP3 amanqanaba asemthethweni.

M4R

MP3

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