MP3 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile MP3 kwaye umguquli ukhetha i AMR codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AMR (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko AMR (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe ezininzi. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum.

Ingaba ukutshintsha MP3 ukuya ku AMR kujikelezo lwesibini lokucinezela okulahlekileyo?

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

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albham iya kuqhubeka iphila kwi MP3 ukuya kwi AMR uguqulo?

Ayiqhelekanga. MP3 ihambisa i-metadata efanelekileyo, kodwa AMR ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshelo, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i MP3 njengekopi ephawulweyo, okanye uphinde uphawule emva koko ngesixhobo njenge Mp3tag okanye iMusicBrainz Picard. I-AMR ibulala umculo: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

I-bitrate yefayili ephumayo AMR iza kusetyenziswa ntoni?

Okungagqibekanga ku 192 kbps kulahleko AMR; dlula- kwi-lossless AMR. 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 MP3 ukuya kwi AMR kuya kunyusa ubunjani besandi sam?

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

Ingaba umguquli MP3 ukuya ku AMR ugcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi MP3 isiqulathi seefayili kwaye ibhalwe kwi AMR isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV ayisebenzi. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo.

Ndingaguqula izigidi zeefayili MP3 zibe AMR?

Ewe - shiya isiqulathi seefayili se MP3 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 AMR iyagcina ixabiso lesampuli elifanayo njenge MP3?

Ngokungagqibekanga ewe — 48 kHz MP3 ihlala 48 kHz kwi AMR. 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 AMR?

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

Ingaba i AMR yam iya kudlala kwi-car stereo, i-iPod, ne-Sonos?

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayisebenzi kwi-iPods edala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esikhupha i-codec AMR esilungele i-hardware yakho emiselweyo. I-AMR isenza ukuba urekhodo lwesandi lube luncinci kakhulu - iyure enye yokuthetha ilungele ii-megabytes ezimbalwa - kwaye yiyo loo nto ifowuni ezininzi zihlala zirekhoda kuyo uqhagamshelwano.

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

Ewe — iifayili ezilayishwe phezulu MP3 ziqhubekeka kubasebenzi abamiselweyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sinikezele kwizinto eziqulethe isandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

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