AMR ukuba AIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili AMR 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-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 AMR ukuya kwi AIFF kuya kunciphisa ubunjani besandi sam?

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

Ingaba i-AMR 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 AMR 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.

Ndingaguqula izigidi zeefayili AMR zibe AIFF?

Ewe - susa isiqulathi seefayili se AMR 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-AMR?

Ngokungagqibekanga ewe (a 48 kHz AMR ivelisa 48 kHz AIFF, a 44.1 kHz AMR 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 AMR 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 AMR ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AMR 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-AMR 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 AMR -> AIFF igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

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

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba ukhetho lokumisela uguquko luvuliwe. Ukuba uziva utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya ingasebenzisa iReplayGain okanye utshintsho lokusebenza oluzenzekelayo kwingoma nganye kumdlalo - khubaza oko kwaye i AIFF ithetha ukuba ifana ne-AMR (ukungabikho kolahleko) okanye ifana ngokubonakalayo (ukungabikho kolahleko olucacileyo).

Ndingaguqula i-AMR yokukhuphela ukusuka kwi-Bandcamp / SoundCloud ibe yi-AIFF?

Ukuba i-AMR ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo ze-DRM (i-Spotify ngaphandle kwe-intanethi, i-Apple Music) zifihliweyo kwinqanaba le-bit kwaye azikwazi kuqhubekekiswa. Amacebo okuthengiswa kwe-Bandcamp, ukulayisha ezantsi kwe-SoundCloud, unikezelo lwepodcast, kunye nokulinganisa komsebenzisi wonke aguqulwa ngokucocekileyo kwi-AIFF.

AMR

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