AMR ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

I-MP3 ifayili isebenzisa i-bitrate enjani?

I-lossy MP3 ikhowudiwe kwi-192 kbps ngokumiselweyo. Isicwangciso Somgangatho Wesandi sinika 320 kbps kumgangatho olungileyo kunye ne-128 kbps kwifayili encinci. I-lossless MP3 (WAV, FLAC) i ignores the bitrate and keeps every sample.

Ingaba ukutshintsha AMR 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-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ndingayiphawula i MP3 ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AMR, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

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. I-AMR ibulala umculo: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

Ingaba ukutshintsha ukusuka ku AMR ukuya ku MP3 kuya kunyusa ubunjani besandi sam?

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

Ndingaguqula izigidi zeefayili AMR zibe MP3?

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-MP3 iya kugcina inqanaba lesampuli elifanayo njenge-AMR?

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

Ndingazilungisa njani ilizwi kwinyathelo AMR ukuya kwi MP3?

Ayiluphi olu hlobo lwendlela. Umguquli awunakucwangcisa ubukhulu besandi kwaye ushiya umphakamo njengonjalo. Ukulinganisa umphakamo, qhuba i MP3 egqityiweyo ngesixhobo Sokugqiba esikwindawo.

Ingaba i-MP3 iyadlala kwi-iPod / i-app yencwadi enesandi?

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 ngangaphambili kule phepha, ngoko khetha ifomati emiselweyo yomdlali wakho oxhasayo.

Ingaba ifayili yam AMR ifihlakeleyo ngexesha lokuguqulwa?

Ewe. Akukho mntu uthetha okanye ubelana ngesandi, esenza kube nzima kwithala leencwadi lencwadi yesandi, kwaye ifayile ezilayishwe phezulu ze AMR kunye nekopi zabo eziguqulweyo zicinywa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa.

AMR

I-AMR yi-codec yokuthetha elungele ukurekhodwa kwelizwi kunye noqhagamshelwano lwefowuni, oko kukuthi, iingoma zengoma zidla ngokubi kuyo.

MP3

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