FLAC ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-FLAC ukuya kwi-AMR iguquli sesandi?

FLAC yisandi engalahlekiyo; AMR ilahlekile. Umguquli uphinde ubhale ikhowudi ye-waveform kwi-bitrate emiselweyo. Isiphumo sincinci kakhulu kodwa sisusa ezinye iziqulatho zesantya esingalunganga - ngokuqhelekileyo zicacile kwi-192 kbps+.

Yintoni i-bitrate endingakhetha kuyo i-AMR?

320 kbps yomgangatho wovimba, 256 kbps yokufunda ngokucacileyo kwisandi esikhulu, 192 kbps yokusasaza, 128 kbps xa ubungakanani befayile bulawula. Ngaphantsi kwe 96 kbps iindidi zezinto zibonakala kwizinto eziqulethe i-percussive.

Ingaba ukuguqulwa kwe-FLAC ukuya kwi-AMR kunokuphinda kuphindeke?

Ungaguqula i-AMR kwakhona kwi-FLAC kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Ingaba iAMR iya kuba ncinci kangakanani na kune-FLAC yam?

Ngokuqhelekileyo 5-10x ngaphantsi kwemifanekiso, 5-15x ngaphantsi kwesandi. Uthelekiso oluchanekileyo luxhomekeke kumphakamo womgangatho okhethiweyo kunye nento equlethe - imifanekiso ethe tyaba-emnyama nesandi esitshixiweyo sicinezela kakhulu kunemifanekiso ethe nkcukacha okanye iingoma zesandi ezixakekileyo.

Ingaba ndilahlekelwe yintoni ngokuguqula FLAC ukuya ku AMR?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. FLAC igcina yonke imilinganiselo ngokuchanekileyo; AMR isusa into eyenza ukuba imodeli yepsychoacoustic ilindele ukuba awuzukuyiva. Kwi-192 kbps nangaphezulu, le mbono ilungile ngokwaneleyo ukuba icacile kwizinto ezininzi kunye neezixhobo ezininzi. Gcina i FLAC njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi AMR. I-FLAC isebenzisa umbono othe tyaba kunye nokukhowuda kweRice ukufezekisa malunga ne-50-60% yobungakanani obuqhelekileyo ngelixa ikhupha ikhowudi kwakhona kwi-PCM efana ne-bit. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albhamu iya kuqhubeka i FLAC ukuya ku AMR uguqulelo?

Ayiqhelekanga. FLAC ihambisa i-metadata efanelekileyo, kodwa AMR ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshi, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i FLAC njengekopi ephawulweyo, okanye uphinde uphawule emva kwesixhobo njenge Mp3tag okanye i MusicBrainz Picard. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Yintoni na i-AMR ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini AMR zingadityaniswa ngokulula ngokubeka enye emva kwenye, kwaye ngokufanayo kutheni konke okungaphezulu kwesandi - ubude, ukukhangela isalathisi, ubugcisa bokuqubha - kufuneka kuboshwe njenge konvensi kunokuba ibe yinxalenye yefomati, ngoko umdlali kufuneka ufunde ifayile yonke usebenze ukuba ide kangakanani. Kumalunga nento elula ebizwa ngokuba yifayile yesandi, eyiyo isizathu sokuba ivela ngaphakathi kwezinye iziqulathi-zifayili rhoqo kuneyo.

Ithini into ebangela ukuba i-audio ekwi-multichannel iguqulwe kwi FLAC ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukhuphelo lwe-downmix lusebenzisa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-mandla zixutywe kwinqanaba eliphantsi. Nantoni na exhomekeke kubekwa kwesiqhagamshelanisi esikhethekileyo siphelile xa oko kwenzeka.

Ezininzi zeefayili zam FLAC zavela kwiCDs - ngaba oku kubaluleke apha?

Kuphela ukuba ukukopela sele kwenzeka kabini. A FLAC okutshatywa kwi diski wacinezelwa nakweyiphi na i bitrate i ripper icwangciswe kwiminyaka edlulileyo, kwaye oko kumgangatho kwizinto zonke ezantsi - ukuguqula akukwazi ukubuyisela into i ripper eshiyekayo. Ukuba i diski ihlala kwi shelf, ukuphinda ukhuphe kwifomati engalahlekiyo nokukhowuda ukusuka apho kunika isiphumo esingcono kunanoma iyiphi ukuguqulwa kwefayile ezikhoyo. I-FLAC yi-Free Lossless Audio Codec, ifomati evulekileyo ukusukela ngo-2001 ecinezela ngaphandle kokususa isampuli enye.

Ingaba FLAC ikhululekile ukuyisebenzisa nokusasaza?

Ewe, ngaphandle kweemeko ezifanele ukukhathazeka ngazo. Ukhankaso luza kufumaneka, wonke umntu angasebenzisa ikhowudi okanye ikhowudi esuka kwikhowudi ngaphandle kokubuza okanye ukuhlawula, kwaye akukho mntu unokuguqula ezi zinto emva - nto leyo eyenza ukuba ivele kwi open- source tooling, kwi engines yemidlalo naphi na apho ilayisensi yokuxoxa ibulala iprojekthi. Ukutshintsha kude nayo akuyi kubuyisela oko; iifayile ozinayo zihlala zisetyenziswa ngokuchanekileyo njengoko zazi.

Ingaba kukho umda wobungakanani befayili xa uguqula i-FLAC ibe yi-AMR?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-FLAC zibe yi-AMR ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze FLAC kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze AMR. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.
