AAC → AIFF

Kāore, ā, e tika ana kia mārama: kāore e taea. Ko te AAC kua whakakoretia te taipitopito i te wā o tōna waehere taketake, ā, ko te whakaroa i te mea e noho ana i roto i tētahi AIFF kāore i te ngaro, ka pupuri tonu i taua mea - kāore anō. He maha ngā wā e nui ake ai te faila, ā, he ōrite ngā pūoro. He mahi tika tonu tēnei i mua i te whakarerekētanga, nā te mea kāore e tāpiri te AIFF i tētahi whakatupuranga tuarua o ngā ahanoa i te wā e kawea atu ai. Ko AIFF te āhua o te whakawhitinga whare taupuni i runga i te macOS, e whakahaere tika ana i te metadata i te WAV noa iho, ā, ka tāurutia ki Logic me Pro Tools. He āhua ā-patent te AAC, ā, he tokomaha nga kaiwhakaari tawhito e whakakāhore ana i a ia i te wāhi e whakaae ana rātau ki te MP3.

I te nuinga o te wā kāore. AAC e whakakōrerotia ana e ngā mea katoa, tae atu ki ngā wae o te waka me ngā kaiwhakaari pakeke; AIFF e hiahiatia ana he pūmanawa e mōhio ana ki te pūkōrero, ā, kāore i te nuinga o te wā e whai ana i ngā pūrere. Mēnā he pūkōrero waka, he kaiwhakaari whakarerekē rānei te ūnga, he tautohe kaha mō te noho i runga i AAC. He nui tonu te AIFF ki te WAV me te tautoko iti iho i waho o te ao Apple, nō reira he kōwhiringa iti mō te tuaritanga.

Ko te pūmau ko te 192 kbps mō te ngaro AIFF; whakawhitinga mō te kore ngaro AIFF. Whakapae ki te 320 kbps mō te pūoro, 96 kbps rānei mō te reo / podcast. Ko te kōwhiringa e whakawhiti ana i te rahi o te pūranga ki te pono whakarongo; i raro iho i te 96 kbps ka kitea ngā huamanu ngaro i runga i te pūoro.

Mēnā he ngaro te AAC ā, he kore ngaro te AIFF (hei tauira, MP3 → WAV), kāore te AIFF i te pai ake i te AAC — kāore e taea e koe te whakaora i ngā mōhiohio kua whakakoretia. Mēnā he kore ngaro te AAC ā, he ngaro te AIFF, ka whakawhāiti anō te AIFF codec; i te 192 kbps he mārama te hua mō te nuinga o ngā ihirangi.

He — e ako ana te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi, me te whakaahua pūrākau mai i te AAC me te tuhi ki te AIFF i reira e tautoko ana te hanga i ngā tohu. Ko ngā ūnga katoa (MP3, AAC, FLAC, OGG) e whakahaere tika ana i ngā tohu; kāore i te WAV raw. Ko AIFF te Apple's Audio Interchange File Format mai i te tau 1988, i hangaia ki runga i te hoahoa porohita IFF ōrite ki te AVI's RIFF.

He — ka tangohia he pūranga o ngā pūranga AAC ki roto, ā, ka tukatuka i a rātou i te whakarara. He nui ake ngā kaimahi whakarara o te utu, ā, kāore he tauine tauine-whakahaere, nā reira ka oti te rōpū 500-file i roto i ngā minu, kaua i ngā tekau minu.

Mā te pūmau, ā, — 48 kHz AAC e noho ana ki te 48 kHz i roto i AIFF. Mēnā e hiahiatia ana e koe te whakaiti hei ōritetanga (96 kHz → 44.1 kHz mō te pūngao CD), ka hoatu te kōwhiringa ā-tauira ki te whakarerekētanga o te āhua o te waeine tiketike i roto i te whakawhitinga waehere ōrite.

He — ka hoatu e te kōwhiringa pūnoa-pūnoa te pūnoa ITU-R BS.1770 / EBU R128 ki te AIFF, e ūnga ana ki -14 LUFS (paerewa rerenga), -16 LUFS rānei (paerewa podcast). Ka whai hua ina whakawātea ngā whakarerekētanga i ngā taumata rerekē.

Ka tākaro te MP3 i ngā wāhi katoa. Ka tākaro te AAC i runga i te Apple, i te nuinga o te Android, me te Sonos. Ka tākaro te FLAC i runga i te Sonos me te Android engari kāore i runga i ngā iPod tahito. Ka tākaro te WAV i runga i ngā mea katoa engari he nui rawa. Ko te whakatūtū-whakahaere-whakahaere-whakahaere e kōwhiri ana i tētahi codec AIFF kua whakawhāititia mō ngā pūrere ūnga.

He — e whakaatatia ana ngā pūranga AAC i whakawāteatia i roto i ngā kaimahi takitahi, ā, ka tangohia i roto i ngā minu. Kāore anō mātou ki te whakataetae, ki te penapena roa, ki te tiritiri rānei i ngā ihirangi oro. Ko te matapihi tauwhāiti katoa i roto i /privacy/.

Ko te kōwae ōrite-re-mux: 10 ki te 30 sekone. Whakawae ki tētahi kōwae rerekē: i te nuinga o te 10 ki te 20% o te roanga pūtake, nā reira he 1-ora AAC → AIFF e whakamutu ana i roto i te 6 ki te 12 min. Ko ngā mahi rōpū e whakatata ana i waenganui i ngā kaimahi mō ētahi atu whakateretanga.
