Tahuri Opus Tuhinga o mua AC3

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te AC3 encoder e mahi ana mai i te oro, kua puta kētia e tētahi whakawhitinga psychoacoustic, ā, ko ōna whakataunga anō e whakakotahi ana i te tautuhi tuatahi. I te 192 kbps, i runga ake rānei i te hua, he mārama tonu te hua mō te nuinga o te whakarongo. Mēnā kei a koe tētahi māngai kore ngaro i tētahi wāhi, ka whakakōrerotia te AC3 mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa. Ko te Opus e whakawhānui ana i te 6 kbps mono speech ki te 510 kbps stereo music i roto i te rererangi ōrite, ā, ka huri noa i ngā āhuatanga. Ko te AC-3 he oro oro maha-kana, i te nuinga o te wā 5.1 i te 384, 448 rānei kBps, me ngā metadata mō te whakawhanaketanga o te kōrero me te whakawhanaketanga.

Kāore i te tīariari. Opus e mau ana i tētahi kōwae metadata tika, engari AC3 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 Opus hei tārua tohu, whakahōu rānei i muri mai me tētahi utauta pēnei i te Mp3tag, MusicBrainz Picard rānei. Kāore te AC-3 i te māia e ngā paerewa o nāianei, ā, kāore e whakaaetia e ngā kaitiaki, ngā pūrongo, te nuinga rānei o ngā kaitapere Wīwī me te kore whakakotahi ki te pūrere.

Ko te pūmau ko te 192 kbps mō te ngaro AC3; whakawhitinga mō te kore ngaro AC3. Whakapae ki te 320 kbps mō te pūoro, 64-96 kbps rānei mō ngā pukapuka oro kōrero (whakaahua mō te reo, he haurua te rahi o te pūranga).

Mēnā he ngaro te Opus ā, he kore ngaro te AC3 (hei tauira, MP3 → WAV), kāore te AC3 faila i te pai ake i te Opus — kāore e taea e koe te whakaora i ngā mōhiohio kua whakawāteatia. Mēnā he kore ngaro te Opus ā, he ngaro te AC3, e tūmanako ana te AC3 codec ki te whakawhāiti anō; i te 192 kbps he mārama tēnei mō te nuinga o ngā ihirangi.

He — ko te taitara, te kaitapere, te pūrākau, te tau, te tau, te tau rererangi, te toi pūrākau, me ngā tohu wāhanga (he hira mō ngā pukapuka oro) e ako ana mai i te Opus, ā, ka tuhituhi ki roto i te AC3 tapawhā i te āhua o te AC3 e tautoko ana i ngā tohu. Ko te hanganga pukapuka oro M4B e haere tata ana ki te M4B me te AAX → M4B huaputa.

He — Ka tangohia he pūrākau o ngā pūranga Opus 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 pūmau, ā, (48 kHz Opus → 48 kHz AC3). Mēnā e hiahiatia ana e koe te whakaiti i te tauira mō te ōritetanga (hei tauira, 96 kHz → 44.1 kHz mō te pūngao CD) ka mahi tēnei te kōwhiringa tauira ā-whakapaina ki te whakawātea ā-whakapaina.

Hei — ka hoatu e te kōwhiringa pūnoa-pūnoa te pūnoa ITU-R BS.1770 / EBU R128 ki te huaputa AC3, e ūnga ana ki -14 LUFS (paerewa rerenga), -16 LUFS (paerewa podcast), -23 LUFS rānei (paerewa pukapuka oro). Ka whai hua ki te tahuri i ngā whakarerekētanga rerekē o ngā rerekētanga.

Ka whakapāpāho te MP3 i te ao whānui. Ka whakapāho te AAC i runga i te Apple, te nuinga o te Android, Sonos. Ka whakapāho te FLAC i runga i te Sonos me te Android, he iti iho te pai i ngā iPods tawhito. Ka whakapāho ngā pukapuka oro M4B me te whakaterenga wāhanga i runga i ngā pukapuka iOS, Audiobookshelf, me te kaiwhakaari Audiobook Smart. Kei roto i ngā kōwhiringa hōhonu ko ngā whakaritenga o mua o te pūrere.

Ko te pūrere ōrite-kore-kore: 10-30 sekone. Whakarerekē i te pūrere rerekē: i te nuinga o te 10-20% o te roanga pūtake, kia oti ai te pukapuka oro 10-ora i roto i te 60-120 minu. Ka ora ngā tohu wāhanga i te haerenga pakeke, ā, ka wehe mārō.
