AIFF kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-AIFF kuya ku-AAC umguquli womsindo?

AIFF yisandi esingalahleki; AAC 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-AAC?

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 AIFF kuya ku AAC ukuguqulwa kubuyiselwa emuva?

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

Ingabe AAC incane kangakanani uma iqhathaniswa ne AIFF 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 AIFF kuya ku AAC?

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. AIFF ligcina yonke imibiko ngokugcwele; AAC 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-AIFF njengenkosi yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-AAC. I-AIFF igcina i-PCM engacindezelwanga enkulu-endian — i-Apple-side elinganayo ne-WAV, nge-bit-for-bit fidelity efanayo. I-AAC ilahlekelwa yizinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design.

Yini okushoyo ihele AAC?

Ukuhamba okuncane kwefremu yomsindo okhonjiswanga ngaphandle kwebhokisi elijikelezayo. Lokhu kusho ukuthi amafayela amabili AAC 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 AIFF ihamba phambili?

Kuphumelela ngokucophelela kunalokho okushiwo. Konke okudlala ngalo namuhla kuzoqhubeka nokudlala - amafomethi angeke aphele ukusebenza - kodwa amakhodethi amasha kanye ne-hardware entsha ikhula iphutha lokushintsha, ngakho imibuzo engokoqobo ukuthi ngabe la mafayela adinga ukuvulwa kulokho okuthengwa eminyakeni eyisithupha namuhla. Kunoma yini ehlukaniswe noma eshicilelwe, ukushintshana kuyi-inshuwalense ephansi. Ku-library yomuntu siqu edlala kahle, ukushiya okukodwa kuyisinqumo esifanele. I-AIFF ikhulu njenge-WAV futhi inezixhaso ezibi ngaphandle kwe-Apple world, ngakho-ke iyisinqumo esibi sokusakaza.

Ingabe AIFF 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.

Ubani ochaza AAC?

Ingxenye yesimo sengqondo hhayi inkampani, okuwukuphela kwento eyenza ukuthi ibe khona. AAC yacaciswa ngenqubo yamazwe omhlaba ekhiqiza isimo seMPEG, ngakho-ke abasakaza, abakhiqizi befoni, abahlinzeki bekhasimende kanye nezinsizakalo zokusakaza zonke zafaka idokhumende elifanayo endaweni yokugunyaza imikhiqizo yomuntu. Imiphumela esebenzayo ibuhlungu futhi isebenziseka: AAC eyenziwe ngethuluzi elinye i-decodes ngokufanayo kusinye, futhi akukho umhlinzeki oxhaswa ngaso kungasuswa. I-AAC iyi-Advanced Audio Coding, ejwayelekile ngo-1997 njenge-MPEG-2 Part 7 futhi ifakwe ngokucacile ukushintsha i-MP3.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-AIFF ibe yi-AAC?

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-AIFF elilodwa libe yi-AAC?

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.

Yini ezoba namafayela ami AIFF ngemuva kokuguqulwa?

Amafayela alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi ahlukaniswe. Ukufaka kanye nohele oluguqulwe kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukuphoqa okuphelele.
