Indlela yokuguqula MP3 ukuba AMR

Inyathelo 1: Layisha eyakho MP3 iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho AMR iifayile

MP3 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

I-bitrate yefayili ephumayo AMR iza kusetyenziswa ntoni?

I-lossy AMR ikhowudiwe kwi-192 kbps ngokumiselweyo. Isicwangciso Somgangatho Wesandi sinika 320 kbps kumgangatho olungileyo kunye ne-128 kbps kwifayili encinci. I-lossless AMR (WAV, FLAC) i ignores the bitrate and keeps every sample.

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. 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 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.

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.

Ndingaguqula izigidi zeefayili MP3 zibe AMR?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

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?

Ayiluphi olu hlobo lwendlela. Umguquli awunakucwangcisa ubukhulu besandi kwaye ushiya umphakamo njengonjalo. Ukulinganisa umphakamo, qhuba i AMR egqityiweyo ngesixhobo Sokugqiba esikwindawo.

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

MP3 idlala phantse naphi na. I-AAC idlala kwizixhobo ze-Apple, ezininzi iifowuni ze-Android kunye ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyikubakho kwi-iPods ezidala, kwaye i-WAV idlala phantse nantoni na kodwa iyenza iifayile ezinkulu. Akukho zixhobo ezimiselweyo ezingaphambili kule phepha, ngoko khetha ifomati emiselweyo yomdlali wakho oxhasayo. 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. Iifayile ezilayishwe phezulu ze MP3 ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe AMR kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

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