MP3 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili MP3 kwaye umguquli ukhetha AMR i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless AMR (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy AMR (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. 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-AMR ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko AMR; dlula-kwi-lossless AMR. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi MP3 ukuya kwi AMR kuya kunciphisa ubunjani besandi sam?

Ukuba MP3 ilahlekile (MP3, AAC) kwaye AMR ayilahleki (WAV, FLAC), i AMR ayingcono kune MP3 — awunakubuyisela ulwazi olusele lulahlekile yi-MP3 codec. Ukuba i MP3 ayilahleki kwaye AMR iyalahleka, lindele ukuba i AMR encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi MP3 isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi AMR isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. 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 - susa isiqulathi seefayili se MP3 kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

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

Ngokungagqibekanga ewe (a 48 kHz MP3 ivelisa 48 kHz AMR, a 44.1 kHz MP3 ivelisa 44.1 kHz AMR). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz AMR yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz AMR — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo MP3 ukuya kwi AMR?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AMR, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-AMR yoluhlu lokudlala.

Ingaba i-AMR iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-AMR codec ekhuselekileyo ye-platform ocacisayo. 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 ifayili yam MP3 ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu MP3 ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

MP3

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

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.
