AAC ukuba AIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-AAC ukuya kwi-AIFF iguquli sesandi?

AAC sele ilahlekile, ngoko ukuguqula kwi AIFF igcina isandi esisekho ngaphandle kokunyuka ezantsi, kodwa ayikwazi ukubuyisela inkcukacha ezilahlekileyo kwikhowudi yokuqala. AIFF ilungile ukuba ucwangcisa ukuhlela nokugcina kwakhona ngaphandle kokudibanisa ii-artifacts zokucinezela.

Ingaba inqanaba lesampuli kunye nobeko lwesiqhagamshelanisi ziya kugcinwa?

Ngokungagqibekanga ewe — i-stereo ihlala i-stereo, i-sample rate emiselweyo (44.1 kHz, 48 kHz, njl.njl.) idluliselwa kwi-AIFF output.

Ingaba ifayili ye AIFF izakuba mkhulu kakhulu kunesiqulathi seefayili se AAC?

Ewe - isandi esingalahlekiyo sihlala singaphezulu nge-5-10x kunesandi esilahlekileyo kwinqanaba lomgangatho ofanayo. Phanda i ~10 MB ngomzuzu ngamnye kwi-AIFF versus ~1 MB ngomzuzu ngamnye kwi-high-bitrate AAC.

Ingaba i-AIFF iya kuba banzi kune-AAC?

Ewe — iziqulatho ezingalahleki zigcina i-byte nganye. Lindela ukuba i-AIFF ibe yi-3-8x ubungakanani be-AAC. Inyani kukuba akukho kufumana kwakhona umgangatho xa uhlela okanye uphinde ubhale kwakhona ikhowudi.

Ingaba ukutshintsha AAC ukuya ku AIFF kunyusa umgangatho wesandi?

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I AAC sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujikelezisa okuseleyo kwi AIFF engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi akhulu kwaye ithetha ngokufanayo. Iyaqhubeka intshukumo elungileyo phambi kohlela, kuba AIFF ayizukongeza udidi lwesibini lwe artefacts xa urhweba ngaphandle. I-AIFF yifomati yotshintshiselwano lwestudio kwi-macOS, iphatha i-metadata kakuhle kune-WAV eqhelekileyo, kwaye ingenisa kwi-Logic ne-Pro Tools ngokukhawuleza. I-AAC ifakwe ipateni, kwaye iqela lee-players ezidala kakhulu zihlala ziyichaza apho bafuna khona i-MP3.

Yintoni na i-AIFF ifayili?

Isiqulathi seefayili esinomsindo ngaphakathi kwayo, kunokuba umsindo ngokwawo. Lo maleko ongaphezulu yindawo apho ubude, isalathisi sokukhangela kunye ne metadata yefomati echazayo igcinwa khona, ngoko umdlali uyazi ukuba i AIFF ihlala ixesha elingakanani phambi kokucoda iframe enye endaweni yokukhangela ifayile yonke ukufumanisa. Oku kuthetha ukuba unikezelo alusoloko lugqiba into engaphakathi: iziqulathi zeefayili ezininzi ezinjalo zivunyelwe ukuba zigcine ngaphezulu kwesinye isifo sesandi, oko kukuthi, iifayile ezimbini AIFF zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo.

Kutheni le nto ifowuni yam okanye i-tablet irekhoda kwi AAC?

Kuba yiyo loo nto i-hardware encoder kwisixhobo ivelisa. Ii-memos zelizwi, ukurekhodwa kwesikrini kunye nokulandela umkhondo wesandi wento erekhodwe kwifowuni ziphuma njenge AAC ngaphandle kokuba umntu ukhetha, oko kukuthi kutheni iifayile ezininzi zifika kuyo kwaye kutheni umgangatho uhlala ungcono kune-ubungakanani befayili ebonisa. Akukho nto malunga nayo imisa ukutshintsha; oku kuthetha kuphela ukuba umthombo wakhowudiwe kabini, yi-chip elungele ukuphila kwebhetri kunokuba kuthembekile. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ingaba i AIFF iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ininzi ingxaki. AAC ikhowudiwe yiyo yonke into, kubandakanya imoto yeqela lenjongo ethile kunye nabadlali abadala; AIFF ifuna udweliso lwenkqubo oluzi ikhowudi, eyona hardware ekhululekileyo ihlala ingakho. Ukuba indawo efanelekileyo yimoto ye stereo okanye umdlali ophathekayo, oku kuyinyani enamandla yokuhlala kwi AAC. I-AIFF ikhulu njenge-WAV enesixhaso esibi ngaphandle kwehlabathi le-Apple, ngoko ke kukhetho olubi lokusasaza.

Ingaba kukho ilayisensi edityaniswe ne AAC?

Akukho nto ofuna ukuyicinga. I-codec iquka i-patent pools, kwaye ilayisensi ibekwe ngumthumeli we-decoder - ifowuni, umkhangeli zincwadi, inkqubo yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke indawo kwihardware, kwaye kutheni i royalty- free alternatives yakhiwa naphi na. Ayitshintshanga nto malunga nokutshintsha ifayile oyinayo, kwaye kumbuzo ophilayo kuphela ukuba uthumeli i-encoder ngokwakho.

Ingaba AIFF ihlala ibalulekile ukutshintsha?

Incwadi yobuqu, ewe; nantoni na oyenzayo umntu, cinga kabini. AIFF iphumelela ngokuthe ngqo kunokuba itshintshwe - konke okudlala ngalo namhlanje kuyaqhubeka nokudlala ngalo - kodwa abakhowudi benkqubo entsha kunye neesixhobo ezintsha zikhula ngokungagqibekanga ukubuyisela, eyenza umsebenzi ofanayo, mhlawumbi. Ukuba ifayile kufuneka ivuleke kuphela kumamatshini akho, ilungile. Ukuba ivula kwisixhobo esivela kwiminyaka emihlanu, khetha enye entsha.

Ingaba kukho umda wobungakanani befayili xa uguqula i-AAC ibe yi-AIFF?

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-AAC zibe yi-AIFF ngaxeshanye?

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