Kodi ndingasinthire bwanji AMR audio ku AIFF popanda kuwonongeka kwabwino?

Kutsitsa fayilo ya AMR ndipo wosinthira wathu amasankha kulumikizana kwa AIFF codec / bitrate komwe kumagwirizana ndi chiyambi. Kulephera kopanda malire (AIFF = WAV / FLAC / ALAC) kumateteza chilichonse; kulephera kopanda malire (AIFF = MP3 / AAC / OGG) kumasinthidwa ku 192 kbps komwe kumawoneka bwino kwa audiobooks olankhula ndi nyimbo zambiri.

Kodi kusinthira AMR ku AIFF kumawonjezera mtundu wa audio?

Sichoncho, ndipo ndibwino kuti mukhale wopanda kanthu: palibe chomwe chingachitike. AMR yomwe yatulutsidwa kale nthawi yoyamba yolemba, ndikuyika zomwe zilibe kanthu AIFF zimasunga zomwezo - sizowonjezera. Fayilo imakula nthawi zambiri ndipo imawoneka ngati yofanana. Ndibe njira yoyenera yosinthira, chifukwa AIFF siyiwonjezera chitukuko chachiwiri cha artefacts pamene mukutumiza. AIFF ndi studio interchange mtundu pa macOS, amasamalira metadata bwino kuposa WAV, ndi kutumiza mu Logic ndi Pro Tools mwamsanga. AMR amawononga nyimbo: yake 8 kHz bandwidth amachotsa zonse pamwamba foni ma frequencies, ndi palibe ndalama ya re-encoding amabweretsa izo kumbuyo.

Kodi AIFF idzasewera m'galimoto yanga kapena pa hardware yakale?

Nthawi zambiri sichoncho. AMR imasinthidwa ndi chilichonse, kuphatikizapo magalimoto agalimoto ndi osewera okalamba; AIFF amafunikira mapulogalamu omwe amadziwa codec, omwe nthawi zambiri amakhala ndi zida zosagwirizana. Ngati malo osankhidwa ndi stereo yagalimoto kapena wosewera wonyamula, ndiye kuti ndi chitsimikizo cholimba chokhala pa AMR. AIFF ndi lalikulu monga WAV ndi zoipa thandizo kunja kwa Apple padziko, kotero ndi woipa kusankha kwa kugawa.

N’chifukwa chiyani nyimbo zimawoneka zoipa kwambiri pa chikhulupiriro?

Chifukwa chimodzi mwazigawo zake ndi codec ya mawu kuposa codec ya nyimbo. Imakhala ndi maonekedwe a munthu woimba ndipo imachotsa chilichonse m’mbali mwa bandwidth ya foni, chomwe ndi choyenera kwa mawu olemba mawu komanso chowononga kwa chilichonse chomwe chili ndi zida. Kusintha kuchokera ku izo sikungabwezeretse ma frequencies osakhudzidwa — iwo sanali kusinthidwa pamalo oyamba.

Kodi bitrate ya AIFF imagwiritsa ntchito?

Default ndi 192 kbps kwa lossy AIFF; pass-through kwa lossless AIFF. Kusintha kwa 320 kbps kwa audiophile kapena 64-96 kbps kwa mawu olankhula audiobooks (owoneka bwino kwa mawu, amadula kukula kwa fayilo).

Kodi kuchoka ku AMR kupita ku AIFF kumachepetsa mtundu wanga wa audio?

Ngati AMR ndi lossy ndipo AIFF ndi lossless (mwachitsanzo MP3 → WAV), fayilo ya AIFF si yabwino kuposa AMR - simungathe kubwezeretsa zambiri zomwe zatulutsidwa. Ngati AMR ndi lossless ndipo AIFF ndi lossy, yembekezerani kuti codec ya AIFF ibwezeretse; pa 192 kbps izi ndi zosawoneka bwino kwa zinthu zambiri.

Kodi wosintha AMR kupita ku AIFF amasunga ID3 / metadata tags?

Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, ndi masamba olemba (ofunika kwambiri kwa audiobooks) amawerengedwa kuchokera ku AMR ndipo amalemba mu AIFF wokhala ndi AIFF mtundu umathandizira ma tag. M4B audiobook structure round-trips into M4B and AAX → M4B output.

Kodi ndingasinthire mamiliyoni a AMR mafayilo ku AIFF?

Yai - chotsani fayilo ya AMR ndikuwapanga mofanana. Premium ili ndi ogwira ntchito ambiri mofanana ndi malire a fayilo, kotero fayilo ya 500-file batch imatha m'maola angapo osati m'maola angapo.

Kodi AIFF idzakhala ndi kuchuluka kwa sampling monga AMR?

Mwachidule ndi yemweyo (48 kHz AMR → 48 kHz AIFF). Ngati mukufuna kuchepetsa kusamvana kwa kugwirizana (mwachitsanzo 96 kHz → 44.1 kHz kwa kulemba CD) kusankha kwa kusamvana kwamphamvu kumachita izi ndi kusamvana kwabwino.

Kodi ndingasinthire kuwala kwamphamvu m'njira ya AMR mpaka AIFF?

Ndiye — njira yosintha mawu imagwiritsa ntchito ITU-R BS.1770 / EBU R128 yosintha mawu ku AIFF, yolenga -14 LUFS (mtengo wosinthira), -16 LUFS (mtengo wosinthira podcast), kapena -23 LUFS (mtengo wosinthira audiobook).

Kodi AIFF idzasewera pafoni yanga yagalimoto / iPod / audiobook app?

MP3 amasewera padziko lonse. AAC amasewera pa Apple, ambiri Android, Sonos. FLAC amasewera pa Sonos ndi Android, osachepera bwino pa zaka zakale iPods. M4B audiobooks kusewera ndi bokosi la navigation pa iOS Buku, Audiobookshelf, ndi Smart Audiobook Player.

Kodi fayilo yanga AMR ndi yapadera panthawi yosintha?

Ndikoyenera - mafayilo a AMR omwe amatulutsidwa amachitidwa m'mabungwe osiyana ndi omwe amagwira ntchito ndipo amachotsa m'maola ochepa. Sitimasewera, sitisunga kapena sitigawana zolemba za audio.
