Tahuri AMR 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 AMR he pūkōrero kōrero whāiti e haere ana i waenganui i te 4.75 me te 12.2 kbps, e tauira ana i te whakawhitinga reo tangata i te wā o te pūoro oro katoa. 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.

Nā te mea he pūkōrero kōrero tētahi taha o te pūkōrero, ehara i te pūkōrero pūoro. E tauira ana i te pūkōrero tangata, ā, ka whakakore i ngā mea katoa i waho o te awhe whatunga, he pai mō te pūrongo reo, he tūkino hoki mō ngā mea katoa me ngā pūrere i roto. Kāore e taea te whakaora i ngā auautanga kāore i te ngaro - kāore anō kia waihangatia i te tuatahi. Ka whakangaromia e AMR te pūoro: ka tangohia e tōna awhe 8 kHz ngā mea katoa i runga ake i ngā auautanga tātari, ā, kāore he nui o te whakakōrerotanga e hoki ana ki a ia.

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 AMR ā, he kore ngaro te AC3 (hei tauira, MP3 → WAV), kāore te AC3 faila i te pai ake i te AMR — kāore e taea e koe te whakaora i ngā mōhiohio kua whakawāteatia. Mēnā he kore ngaro te AMR 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 AMR, 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 AMR 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 AMR → 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.

Yes — uploaded AMR files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. Especially important when working with personal audiobook libraries.

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.
