AAC → WAV

Kāore, ā, e tika ana kia mārama: kāore e taea. Ko te AAC kua whakakoretia kētia ngā taipitopito i te wā o tōna waehere taketake, ā, ko te whakaroa i te mea e noho ana i roto i tētahi WAV kāore i te ngaro, ka pupuri tonu - 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 WAV i tētahi whakatupuranga tuarua o ngā ahanoa i te wā e kawea atu ai. Ko te WAV te āhua tika mō te whakahua, te whakahauhau me te pūranga, nā te mea ka taea te whakakōrero anō i ētahi wā me te kore e whakatōpū i ngā ahanoa. 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.

Kāore i te tīariari. AAC e mau ana i tētahi kōwae metadata tika, engari WAV kāore he wāhi paerewa mō te kaitapere, pūrākau, tau rererangi, toi rānei, nā reira ka whakawāteatia ngā tohu i te kore e whakawāteatia. Whakataki te AAC hei tārua tohu, whakahōu rānei i muri mai me tētahi utauta pēnei i te Mp3tag, MusicBrainz Picard rānei. He tino nui te WAV — tata ki te 10 MB ia minu i te āhuatanga CD — ā, he 4 GB te tauine o te āhua o te pūrākau, ā, kāore he wāhi mō ngā tohu tika.

Ko te pūmau ko te 192 kbps mō te ngaro WAV; whakawhitinga mō te kore ngaro WAV. 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 hua o te ngaro i runga i te pūoro.

Mēnā he ngaro te AAC ā, he kore ngaro te WAV (hei tauira, MP3 → WAV), kāore te WAV 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 WAV, ka whakawhāiti anō te WAV 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 o te whakataki, me te whakaahuatanga pūrākau mai i te AAC me te tuhi ki te WAV 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 te WAV mārō. Ko te WAV he pūrere oro i runga i te Microsoft me IBM RIFF mai i te tau 1991, ā, ko te mea tata tonu ki ngā whakawhitinga oro me ngā DAW e tuhi ana i runga i te pūkete.

He — Ka tangohia he pūrākau o ngā pūranga AAC ki roto, ā, ka whakamātautau mātou i a rātou i te whakarara. He nui ake ngā kaimahi whakatata o te Premium, ā, kāore he tauine tauine-whakahaere, nā reira ka oti te rōpū 500-file i roto i ngā minu, kaua ko ngā tekau minu.

Mā te tīpako, ā, — 48 kHz AAC e noho ana 48 kHz i WAV. Mēnā e hiahiatia ana e koe te whakaiti i te ōritetanga (96 kHz → 44.1 kHz mō te pūkōrero CD), ka hoatu te kōwhiringa tātauira ki te whakawātea ā-whakahaere i te whakawhitinga waehere ōrite.

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

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

He — e whakarewaina ana ngā pūranga i whakarewaina AAC ki ngā kaimahi motuhake, ā, ka whakakoretia i roto i ngā minu. Kāore anō tātau ki te whakataetae, ki te rokiroki roa, ki te tiritiri rānei i ngā ihirangi oro. Ko te matapihi tautuhi katoa i roto i /privacy/.

Ko te pūrere ōrite-kōrero-whakahaere: 10 ki te 30 sekona. Whakawa-kōrero ki tētahi pūrere rerekē: i te nuinga o te 10 ki te 20% o te roanga pūtake, nā reira he 1-ora AAC → WAV e whakamutu ana i roto i te 6 ki te 12 minu. Ko ngā mahi rōpū e whakatata ana i waenganui i ngā kaimahi mō ētahi atu whakateretanga.
