FLAC kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-FLAC kuya ku-AMR umguquli womsindo?

FLAC yisandi esingalahleki; AMR yisandi esilahlekile. Umguquli uphinde uhlanganise i-waveform nge-bitrate elungiswe. Isiphumo sincane kakhulu kodwa sisusa ezinye izithako zezinga lokusakaza elingazizwanga — ngokuvamile zicacile ku-192 kbps+.

Yini i-bitrate okufanele ngiyikhethe ku-AMR?

320 kbps ukhwalithi yomlando, 256 kbps ukulalela okucacile kuma-speakers amaningi, 192 kbps ukusakazwa, 128 kbps uma ubukhulu befayela bulawula. Kungaphansi kuka-96 kbps, ama-artefacts atholakali ku-percussive content.

Ingabe FLAC kuya ku AMR ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-AMR emuva ku-FLAC kule site. Uma ifomethi eyodwa ilahlekile, i-round-trip ayilungile noma ngabe ibukeka noma izwakala ifana.

Ingabe AMR incane kangakanani uma iqhathaniswa ne FLAC yami?

Ngokuvamile 5-10x ncane ngezithombe, 5-15x ncane ngesandi. Ulinganiso ofanele uxhomekeke kuzinga lomgangatho olukhethiwe kanye nesihloko — izithombe ezimhlophe eziqinile nesandi esingenalutho sicindezela kakhulu kunezithombe ezicacile noma izingoma ezisebenza kakhulu.

Ingabe ngilahlekelwa yikhwalithi eningi uma ngiguqula FLAC kuya ku AMR?

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. FLAC ligcina yonke imibiko ngokugcwele; AMR lisusa lokho imodeli ye-psychoacoustic icabanga ukuthi awuzokwazi ukulalela. Ku-192 kbps futhi ngaphezu kwalokho, i-prediction iyilungile ngokwanele ukubukeka kuningi kwamathuluzi namanye amathuluzi. Gcina i-FLAC njengenkosi yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-AMR. I-FLAC isebenzisa ukubikezela okuqondile kanye nokuhlelwa kwe-Rice ukufinyelela cishe ku-50-60% wesayizi yangempela ngesikhathi sokuhlelwa emuva kwe-PCM efana ne-bit. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum.

Ingabe izihloko zesikhashana sami kanye nesithombe se-albhamu sizohlala isikhathi eside uma siguqulwa FLAC kuya ku AMR?

Akunalutho. FLAC ifaka i-metadata efanele, kodwa AMR ayinaso isikhala esijwayelekile somuntu oculi, i-albhamu, inani le-track noma umhlobiso we-cover, ngakho-ke amathegi asuswa ngaphandle kokulahleka. Gcina i-FLAC njengekhophi elabelwe, noma uphinde ubeke i-tag ngemuva ngethuluzi njenge Mp3tag noma MusicBrainz Picard. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Yini okushoyo ihele AMR?

Ukuhamba okuncane kwefremu yomsindo okhonjiswanga ngaphandle kwebhokisi elijikelezayo. Lokhu kusho ukuthi amafayela amabili AMR angaxhunywa ngokulula ngokubeka elinye ngemuva kwelinye, futhi ngokufanayo kusho ukuthi konke okungaphezu komsindo - ubude, ukufuna isibalo, ukuhoxa umdwebo - kufanele kufakwe ibhodlela njengenhlanganiso ngaphezu kokuyingxenye yefomethi, ngakho umdlali kufanele afunde ihele lonke ukuze asebenze ukuthi lide kangakanani. Kulokhu, into elula kakhulu ebizwa ngokuthi ihele lomsindo, okuwukuthi kungani livela ngaphakathi kwezinye izibhokisi ngaphezu kokuvela ngokwalo.

Ingabe FLAC imahhala ukuyisebenzisa nokusakaza?

Yebo, ngaphandle kwezimo ezifanele ukukhathazeka ngazo. Ulwazi olucacisiwe luyiqiniso, wonke umuntu angafaka umbhalo-mbhalo noma umbhalo-mbhalo oguquliwe ngaphandle kokubuza noma ukukhokha, futhi akukho muntu ongashintsha la mazwi ngemuva - ngakho-ke kuvela ku-open-source tooling, kuma-engine wemidlalo nakwezinye izindawo lapho i-license negotiation ibulala iphrojekthi. Ukushintshana isuka kuyo akuyibuyisela emuva lokho; amafayela akhona ahlala ngokugcwele njenge-useable njengoba bekhona.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke ngaphandle kwe-bandwidth yefoni, elungile ku-voice memo futhi ebulalayo kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela ama-frequencies angekho — angeke abhalwe ngokucophelela endaweni yokuqala. FLAC akazange ashintshe, futhi Apple's ecosystem kuphela engeza insizakalo okwamanje futhi grudgingly.

Kungani umuntu angaguqula ku AMR?

Kuye kungxenyekazi eyodwa noma ihardware ekhethekile engeke ithathe noma yini enye - okuwumphumela ongokoqobo kanye nesizathu esingcono kuphela. AMR ihlobene nohlobo oludlule: ama-codecs amasha asebenza ngokufanayo kubukhulu obuncane, abadlali abazosebenzisa ngokuvamile bashiya ukuxhaswa kwayo endaweni yokungeza, futhi akukho okusha okuzokwakhiwa kuyo. Uma kukhona okuthile emgodini ofuna okuthile, guqula futhi ugcine okujwayelekile njengomkhulu. Uma akukho okukwenzayo, guqula kude nayo.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-FLAC ibe yi-AMR?

Ukuguquka okumahhala kunesilinganiselo sobukhulu sehele ngalinye, esisetshenzisiwe ngohlobo lwehele, futhi ikhasi lizokutshela uma ihele lidlula kulo. Iphrojekthi ekhokhelwayo isusa lesi silinganiselo, ngakho amafayela amakhulu angaguqulwa.

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-FLAC elilodwa libe yi-AMR?

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

FLAC

I-FLAC inikeza ukucindezelwa komsindo okungenakulahlekelwa, kunciphisa usayizi wefayela ngenkathi kulondolozwa ikhwalithi yomsindo yokuqala engu-100%.
