Indlela yokuguqula AAC ukuba AIFF

Inyathelo 1: Layisha eyakho AAC iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho AIFF iifayile

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 nomcebo. Isiphelo esingalahliweyo (AIFF = WAV / FLAC / ALAC) sigcina isampuli nganye; isiphelo esilahliweyo (AIFF = MP3 / AAC / OGG / Opus) simiselwe kwi-192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-AIFF ifayili isebenzisa i-bitrate enjani?

Okumiselweyo 192 kbps ye-lossy AIFF; idlula-kwi-lossless AIFF. Nciphisa ukuya kwi-320 kbps ye-audiophile, 256 kbps ye-high-quality music, okanye i-96 kbps yelizwi/podcast. Ukhetho lutshintshisa ubungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwi-bitrates ephantsi kakhulu.

Ingaba ukutshintsha ukusuka ku AAC ukuya ku AIFF kuya kunyusa ubunjani besandi sam?

Ukuba AAC ilahlekile kwaye AIFF ayilahleki (umzekelo MP3 → WAV), ifayili AIFF ayingcono kune-AAC - awunakubuyisela ulwazi olulahlekileyo oluthunyelwe yi-encoding elahlekile yokuqala. Ukuba AAC ayilahleki kwaye AIFF ayilahleki, lindele ukuba i-AIFF codec iphinde icinezele; kwi-192 kbps oku kucacile kuzo zonke izinto.

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

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, imifanekiso ye-albham efakwe ngaphakathi ifundwa kwi AAC isiqulathi seefayili kwaye ibhalwe kwi AIFF isiqulathi seefayili (ifomati nganye yesandi eqhelekileyo ixhasa iziphawuli). Iziphawuli ziyaphila nokuba i-codec ephantsi itshintsha.

Ndingaguqula izigidi zeefayili AAC zibe AIFF?

Ewe - susa isiqulathi seefayili se AAC ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi. Iimpawu kunye nokwakhiwa kwesiqulathi seefayili zigcinwa.

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

Ngokungagqibekanga ewe — 48 kHz AAC → 48 kHz AIFF, 96 kHz → 96 kHz. Ukuba ufuna ukunyusa isampuli ukuhambelana (96 kHz studio masters → 44.1 kHz for CD burning), ukhetho lwesampuli-yexabiso eliphambili lusebenzisa isampuli ephezulu-yexabiso (libsoxr okanye sox-elinganayo) ngaphandle kokubonwa kwe-alias.

Ndingazilungisa njani ilizwi kwinyathelo AAC ukuya kwi AIFF?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AIFF, ibeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kutshintshwa iqela lelayibrari edityanisiweyo apho imikhondo ineemphakamo zokuphatha ezitshintshayo.

Ingaba i-AIFF iya kudlala kwi-stereo yemoto yam, i-iPod, okanye i-Sonos?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esidityanisiweyo kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos, i-Android, nezixhobo eziphambili zemoto eziphambili; zisebenza kakuhle kakhulu kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ikhulu. Ukhetho lwesixhobo esimiselweyo lukhetha i-AIFF codec ekhuselekileyo yenjongo.

Ingaba ifayili yam AAC ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AAC ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu embalwa emva kokuphela. Asiyi kudlala, sigcine, sisebenzise i-fingerprint, okanye sisebenzise imixholo yesandi. Ifestile epheleleyo yokugcina i-data ibhalwe kwi /privacy/.

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

I-codec efanayo yoku-multiplex (umzekelo, i-FLAC ijikeleza ngaphakathi komgcini weefayili enye itshintshwa kwenye): 10-30 imizuzwana. Yenza kwakhona i-encoding kwi-codec eyahlukileyo: ngokuqhelekileyo 10-20% yobude bomthombo, ngoko ke i-1-iyure AAC → AIFF igqiba kwimizuzu eyi-6-12.

Kutheni i-AIFF ifayili inamandla okanye ipholile kune-AAC imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uyenze ngokucacileyo ukhetho lokutshintsha. Ukuba ubona utshintsho lomphakamo kwixesha lokudlala, umdlali wakho wesandi okanye ilayibrari yemidiya ingasebenzisa iReplayGain okanye utshintsho lomlinganiselo lwengoma nganye kwi-i-yodwa — leyo ngumdlali, hayi i-pipeline yethu.

Ndingaguqula i AAC i-streaming downloads kwi AIFF?

Ukuba i-AAC ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo nge-DRM (i-Spotify ngaphandle kwe-intanethi, i-Apple Music) zifihliweyo kwinqanaba le-byte kwaye asikwazi ukuzikhupha okanye ukuziqhubekekisa. Amacebo e-Bandcamp, i-SoundCloud, i-archive.org, kunye nokulinganisa kobuntu buguqulwa ngaphandle kwengxaki.
