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

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

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

AIFF ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili AIFF kwaye umguquli ukhetha AMR i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (AMR = WAV / FLAC / ALAC) sigcina isampuli nganye; isiphelo esilahliweyo (AMR = MP3 / AAC / OGG / Opus) simiselwe kwi-192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-AMR ifayili isebenzisa i-bitrate enjani?

Okumiselweyo 192 kbps ye-lossy AMR; idlula-kwi-lossless AMR. 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 AIFF ukuya ku AMR kuya kunyusa ubunjani besandi sam?

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

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

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

Ndingaguqula izigidi zeefayili AIFF zibe AMR?

Ewe - susa isiqulathi seefayili se AIFF 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-AMR iya kugcina inqanaba lesampuli elifanayo njenge-AIFF?

Ngokungagqibekanga ewe — 48 kHz AIFF → 48 kHz AMR, 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 AIFF ukuya kwi AMR?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AMR, 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-AMR 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-AMR codec ekhuselekileyo yenjongo.

Ingaba ifayili yam AIFF ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AIFF 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-AIFF yeyure enye ibe yi-AMR?

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 AIFF → AMR igqiba kwimizuzu eyi-6-12.

Kutheni i-AMR ifayili inamandla okanye ipholile kune-AIFF 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 AIFF i-streaming downloads kwi AMR?

Ukuba i-AIFF 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.

AIFF

I-AIFF (i-Audio Interchange File Format) yifomathi yefayile yeaudio engaxinzelelwanga edla ngokusetyenziswa kwimveliso yomsindo kunye nomculo.

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.
