Guqula MP3 ukuba AMR

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. 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.

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.

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.

Okumiselweyo yi-192 kbps ye-lossy AMR; igqityiwe-kwi-lossless AMR. Nciphisa kwi-320 kbps ye-audiophile okanye 64-96 kbps ye-audiobooks yegama elithethayo (elibonisa ngaphaya lelizwi, liphelisa ubungakanani befayili).

Ukuba MP3 ilahlekile kwaye AMR ayilahleki (umzekelo MP3 → WAV), ifayili AMR ayingcono kune MP3 — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba MP3 ayilahleki kwaye AMR ilahlekile, lindele ukuba i-AMR codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, kunye nabaphawuli besiqendu (ababalulekileyo kwiincwadi zesandi) bafundwa ukusuka kwi MP3 kwaye babhalwe kwi AMR isiqulathi seefayili apho i-AMR ifomati ixhasa ii-tags. Ukwakhiwa kwencwadi yesandi ye-M4B ijikeleza-jikeleza kwi-M4B ne-AAX → i-M4B i-output.

Ewe - susa isiqulathi seefayili se MP3 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.

Ngokungagqibekanga ewe (48 kHz MP3 → 48 kHz AMR). Ukuba ufuna ukunyusa isampulu ukuhambelana (umzekelo. 96 kHz → 44.1 kHz yokushicilela i-CD) ukhetho lwesampulu-yexabiso eliphambili yenza oku ngesampulu ephezulu yomgangatho.

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AMR, ibeka i- -14 LUFS (isiqhelo sokusasaza), -16 LUFS (isiqhelo sepodcast), okanye -23 LUFS (isiqhelo sencwadi enesandi). Isetyenziswa xa kuguqulwa iingoma ngemiphakamo emininzi yolawulo.

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, isebenza kakuhle kwi-iPods edala. Iincwadi zesandi ze-M4B zidlala ngesahluko sokuhamba kwi-iOS Books, i-Audiobookshelf, kunye ne-Smart Audiobook Player. Iinketho eziphambili ziquka i-preset yesixhobo.

Ewe — iifayile ezilayishwe phezulu MP3 ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Kubalulekile ngakumbi xa usebenza neelayibrari zencwadi yesandi yobuqu.
