Kodi ndingasinthire bwanji AMR audio kupita ku AIFF popanda kuwononga mtundu?

Kutsitsa fayilo ya AMR ndipo wosintha amasankha kulumikizana kwa AIFF codec / bitrate komwe kumagwirizana ndi fayilo ya chiyambi. AIFF yopanda kusowa (WAV / FLAC / ALAC) imasunga zonse mwatsatanetsatane; AIFF yowonongeka (MP3 / AAC / OGG / Opus) imayikidwa ku 192 kbps yomwe ndi yosawoneka bwino kwa pafupifupi zonse zomwe zili ndi nyimbo. AMR ndi narrowband mawu codec kuyendetsa pakati pa 4.75 ndi 12.2 kbps, modeling munthu woimba m'mimba kuposa wonse audio spectrum. AIFF amasunga PCM yosasinthika ya big-end — yomwe ndi yofanana ndi WAV ya Apple, ndi kusamvana kwa bit-by-bit.

Kodi kusinthira AMR ku AIFF kumawonjezera mtundu wa audio?

Sichoncho, ndipo ndibwino kuti mukhale wopanda kanthu: palibe chomwe chingachitike. AMR chomwe chatha kuchotsa mfundo zazikulu panthawi yake yoyamba yolemba, ndikuyika zomwe zilibe kanthu AIFF zimasunga zomwe zilibe kanthu - sichoncho. 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 pa izo sikungabwezeretse ma frequencies osakhudzidwa — iwo sanali kusinthidwa pamalo oyamba.

Kodi ndi bitrate iti yomwe fayilo ya AIFF imatha?

Default 192 kbps for lossy AIFF; pass-through for lossless AIFF. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-restricted podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.

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

Ngati AMR ndi yowonongeka (MP3, AAC) ndi AIFF ndi yopanda kusowa (WAV, FLAC), AIFF si yabwino kuposa AMR - simungathe kubwezeretsa zambiri zomwe zatulutsidwa ndi AMR codec yowonongeka. Ngati AMR ndi yopanda kusowa ndi AIFF ndi yopanda kusowa, yembekezerani kuti AIFF encoder ibwezeretse; pa 192 kbps kuwonongeka kumakhala kosadziwika kwa nkhope zambiri.

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

Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, BPM, kusewera-kupeza kumawerengedwa kuchokera ku AMR chomera ndi kulemba m'madera ofanana pa AIFF chomera. ID3v2 (MP3), Vorbis maganizo (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chidutswa zonse map cleanly. AIFF ndi Apple Audio Interchange File Format kuchokera 1988, anamanga pamodzi IFF chunk kupanga monga AVI RIFF.

Kodi ndingasinthire ma AMR ambiri a AIFF?

Yes — chotsani fayilo ya AMR ndipo tidzazipanga mofanana. Premium ili ndi ogwira ntchito ambiri mofanana ndi malire a fayilo, kotero fayilo ya 500 imatha m'maola ochepa kuposa maola asanu. Mtundu wa fayilo umasungidwa mu ZIP yotulutsidwa.

Kodi AIFF idzakhala ndi kuchuluka kwa sampling yomweyo ngati AMR?

Mwa default ndi yemweyo (48 kHz AMR imatulutsa 48 kHz AIFF, 44.1 kHz AMR imatulutsa 44.1 kHz AIFF). Kuti mukwaniritse zofunikira — monga kuchepetsa 96 kHz studio masters mpaka 44.1 kHz AIFF polemba CD, kapena kuwonjezera 22 kHz voicemail mpaka 44.1 kHz AIFF — mndandanda wolowetsa wa sampling-rate umagwiritsa ntchito kuwonjezera kwa SOX-style.

Kodi ndingasinthire kuwala kwa mawu m'mawindo a AMR mpaka AIFF?

Ndiyo — kusankha kwa loudness-normalize kumagwiritsa ntchito ITU-R BS.1770 / EBU R128 ku AIFF output, kulenga -14 LUFS (streaming standard) kapena -16 LUFS (podcast standard) kapena malire apadera. Kuthandiza pamene mukusintha nyimbo ndi zigawo zosiyanasiyana za mastering kukhala imodzi AIFF playlist.

Kodi AIFF idzasewera pa stereo yagalimoto yanga / iPod / Sonos / wokamba nkhani wa Bluetooth?

MP3 imasewera padziko lonse lapansi pazinthu zonse zomwe zidapangidwa mzaka zapitazi 20. AAC imasewera pa Apple, ambiri a Android, Sonos, ndi ma stereo amakono agalimoto. FLAC imasewera pa Sonos ndi Android yaposachedwa, osati bwino pa iPods oyambirira. WAV imasewera pa chilichonse koma fayilo ndi yayikulu. Kuwonekera kwa chipangizocho chimasankha AIFF codec yotetezeka kwa pulogalamu yomwe mumasankha.

Kodi fayilo yanga AMR ndi yachikhalidwe panthawi yosintha?

Ndikofunika — fayilo AMR yotulutsidwa imathetsedwa m'maola ochepa. Tisasewera, sitisunga kapena sitigawana zolemba za audio. Mzerewu umagwira ntchito pa zida zomwe timayang'anira kuyambira pachiyambi mpaka kumayambiriro; palibe ntchito yachitatu yomwe imalandira fayilo yanu.

AMR

AMR (Adaptive Multi-Rate) ndi mtundu wamawu wokongoletsedwa kuti azitha kukopera mawu. Amagwiritsidwa ntchito kwambiri m'mafoni a m'manja pojambula mawu komanso kusewera.
