Kutsitsa fayilo ya AAC 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.
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 AAC kupita ku AIFF kumachepetsa kwambiri mtundu wanga wa audio?
+
Ngati AAC ndi yowonongeka (MP3, AAC) ndi AIFF ndi yopanda kusowa (WAV, FLAC), AIFF si yabwino kuposa AAC - simungathe kubwezeretsa zambiri zomwe zatulutsidwa ndi AAC codec yowonongeka. Ngati AAC ndi yopanda kusowa ndi AIFF ndi yopanda kusowa, yembekezerani kuti AIFF encoder ibwezeretse; pa 192 kbps kuwonongeka kumakhala kosadziwika kwa nkhope zambiri.
Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, BPM, kusewera-kupeza kumawerengedwa kuchokera ku AAC 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.
Kodi ndingasinthire ma AAC ambiri a AIFF?
+
Yes — chotsani fayilo ya AAC 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 AAC?
+
Mwa default ndi yemweyo (48 kHz AAC imatulutsa 48 kHz AIFF, 44.1 kHz AAC 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 AAC 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 AAC ndi yachikhalidwe panthawi yosintha?
Kodi ndi nthawi yayitali bwanji kuti musinthe nthawi ya 1-hour AAC kuti AIFF?
+
Kusintha kwa codec (mwachitsanzo, FLAC -> MP3 kapena WAV -> AAC): nthawi zambiri 10-20% ya nthawi yoyambira, choncho 1-hour AAC -> AIFF imatha m'maola 6-12 pa chingwe cha standard.
N'chifukwa chiyani fayilo ya AIFF ndi yolimba kapena yolimba kuposa AAC yochokera?
+
Sizimachitika kusintha kwa kuwonjezeka kwa mavidiyo mwamsanga ngati njira yosintha mavidiyo kukhala oyenera siyikugwira ntchito. Ngati mumaona kusintha kwa mavidiyo, wosewera mavidiyo kapena laibulale ya mavidiyo angagwiritse ntchito ReplayGain kapena kusintha kwa mavidiyo pamodzi pamasewera - chotsani izo ndipo AIFF idzawoneka yofanana ndi AAC (yopanda kuwonongeka) kapena yofanana ndi AAC (yokhala ndi kuwonongeka kowonekera).
Kodi ndingasinthire kutsitsa kwa AAC kuchokera ku Bandcamp / SoundCloud kupita ku AIFF?
+
Ngati kutsitsa kwa AAC sikuteteza (sinali DRM), yeah. Mafayilo a DRM omwe amasungidwa (Spotify osagwirizana, Apple Music) amasungidwa pazenera la bit ndipo sangathe kuchitidwa. Mafuta a Bandcamp, SoundCloud go downloads, podcast feeds, ndi zolemba za munthu zonse zimasinthidwa moyenera ku AIFF.
