AAC ukuba AIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AAC yesandi ibe yi-AIFF ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili AAC kwaye umguquli ukhetha AIFF i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless AIFF (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy AIFF (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba iboniswe kwi-stereo design. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo.

Ingaba ukutshintsha i-AAC ukuya kwi-AIFF kunyusa umgangatho wesandi?

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

Ingaba i AIFF iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ihlala ingasebenzi. AAC ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; AIFF ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi AAC. I-AIFF ikhulu njenge-WAV enesixhaso esibi ngaphandle kwehlabathi le-Apple, ngoko ke kukhetho olubi lokusasaza.

I-AIFF ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko AIFF; dlula-kwi-lossless AIFF. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi AAC ukuya kwi AIFF kuya kunciphisa ubunjani besandi sam?

Ukuba AAC ilahlekile (MP3, AAC) kwaye AIFF ayilahleki (WAV, FLAC), i AIFF ayingcono kune AAC — awunakubuyisela ulwazi olusele lulahlekile yi-AAC codec. Ukuba i AAC ayilahleki kwaye AIFF iyalahleka, lindele ukuba i AIFF encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

Ingaba i-AAC ukuya kwi-AIFF igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi AAC isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi AIFF isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. I-AIFF yi-Apple's Audio Interchange File Format ukusukela ngo-1988, ibekwe kwi-IFF chunk design efanayo ne-AVI's RIFF.

Ndingaguqula izigidi zeefayili AAC zibe AIFF?

Ewe - susa isiqulathi seefayili se AAC kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

Ingaba i-AIFF iya kugcina inqanaba lesampuli elifanayo njenge-AAC?

Ngokungagqibekanga ewe (a 48 kHz AAC ivelisa 48 kHz AIFF, a 44.1 kHz AAC ivelisa 44.1 kHz AIFF). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz AIFF yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz AIFF — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo AAC ukuya kwi AIFF?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AIFF, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-AIFF yoluhlu lokudlala.

Ingaba i-AIFF iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-AIFF codec ekhuselekileyo ye-platform ocacisayo.

Ingaba ifayili yam AAC ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AAC ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

Ithatha ixesha elingakanani ukutshintsha i-AAC yeyure enye ibe yi-AIFF?

I-codec efanayo yoku-multiplex (umzekelo. AAC ngaphakathi kwe-M4A -> AAC ngaphakathi kwe-MP4): imizuzwana eyi-10-30. Utshintsho lwe-codec (umzekelo. FLAC -> MP3 okanye WAV -> AAC): ngokuqhelekileyo i-10-20% yobude bomthombo, ngoko ke i-1-iyure AAC -> AIFF igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.
