Tahuri M4A Tuhinga o mua OGG

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te OGG 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 OGG mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa. Kei roto i te M4A te AAC i te nuinga o nga take, Apple Lossless rānei (ALAC) ina puta mai i tētahi tāruatanga kore. He ngaro te Vorbis i roto i te OGG, ā, ka whakamahia te mokatere tāupe mā te pūmau, nō reira ka whakaritea te āhuatanga hei taumata ehara i te taupū kbps pūmau.

DRM. He pūrere ā-roto o ngā pūranga M4A kua whakawaeheretia e te puna, te pūmanawa rānei i tukuna, ā, kāore e taea te whakawaehere i te oro whakawaeheretia e tētahi kaiwhakarere. Ko ngā mea katoa i whakawāteatia e koe, i whakakōrerotia, i hokona rānei me te kore parenga, ka whakawhiti i te āhua noa; kāore e hokona tētahi ārai. E rua nga mea rerekē e whakawāteatia ana e M4A i muri i tētahi whakaroanga — AAC ngaro me ALAC kore ngaro — ā, kāore te tautoko ā-Apple i te ōrite.

I te nuinga o te wā kāore. M4A e whakakōrerotia ana e ngā mea katoa, tae atu ki ngā wae o te waka me ngā kaiwhakaari pakeke; OGG 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 M4A. He iti rawa te tautoko a OGG mo nga taonga — ko nga pūrere waka, ko ngā iPod tahi, me te maha o ngā pouaka whakaata kāore e kitea te faila.

Ko te pūmau ko te 192 kbps mō te ngaro OGG; whakawhitinga mō te kore ngaro OGG. 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 M4A ā, he kore ngaro te OGG (hei tauira, MP3 → WAV), kāore te OGG faila i te pai ake i te M4A — kāore e taea e koe te whakaora i ngā mōhiohio kua whakawāteatia. Mēnā he kore ngaro te M4A ā, he ngaro te OGG, e tūmanako ana te OGG 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 M4A, ā, ka tuhituhi ki roto i te OGG tapawhā i te āhua o te OGG 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 M4A 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 M4A → 48 kHz OGG). 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 OGG, 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 M4A 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.
