M4A Tuhinga o mua OGG Ngā Pātai Auau mō te Tahuritanga

He pēhea te tahuri i a au i te M4A oro ki OGG me te kore e ngaro te āhuatanga?

Whakataki i te M4A me te kaikōrero e kōwhiri ana i te OGG codec me te bitrate hei ōrite ki te pūtake. Kāore i te ngaro OGG (WAV / FLAC / ALAC) e pupuri ana i ia tauira i te pēhi; ko te ngaro OGG (MP3 / AAC / OGG / Opus) te pūmau ki te 192 kbps e mārama ana mo te nuinga o ngā oro. 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.

He whakawhitinga te M4A ki te OGG he porowhita tuarua o te whakawhāiti ngaro?

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 ārai katoa i te whakawhitinga rua.

He aha te take kāore e tahuri ana ētahi o a ahau M4A?

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 tikanga; kāore e whakawāteatia te hoko ā-whakahaere. 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.

Ka tākaro te OGG i roto i tōku waka, i runga rānei i ngā pūrere tawhito?

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.

He aha te bitrate ka whakamahia e te pūkete OGG?

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, 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.

Ka whakaiti te haere mai i te M4A ki te OGG i te āhuatanga o ahau?

Mēnā he ngaro te M4A ā, he kore ngaro te OGG (hei tauira, MP3 → WAV), kāore te OGG i te pai ake i te M4A — kāore e taea e koe te whakaora i ngā mōhiohio kua whakakoretia. Mēnā he kore ngaro te M4A ā, he ngaro te OGG, ka whakawhāiti anō te OGG codec; i te 192 kbps he mārama te hua mō te nuinga o ngā ihirangi.

E pupuri ana te M4A ki te OGG kaiwhakarere i ngā tohu ID3 / metadata?

He — e ako ana te taitara, te kaitapere, te pūrākau, te tau, te tau o te whakataki, me te whakaahuatanga pūrākau mai i te M4A me te tuhi ki te OGG 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 OGG te pūrere Xiph.Org, i te nuinga o te wā e pupuri ana i te oro Vorbis, i hangaia i te tau 2000 hei whirinoa kāore i te whakawhāiti ki te MP3.

Ka taea e au te tahuri i nga rau o nga pūranga M4A ki OGG?

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.

Ka pupuri te OGG i te ōritetanga tauira pēnei i te M4A?

Mā te tīpako, ā, — 48 kHz M4A e noho ana 48 kHz i OGG. 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.

Ka taea e au te whakawātea i te pūoro ina tahuri M4A ki OGG?

He — ka hoatu e te kōwhiringa pūnoa-pūnoa te pūnoa ITU-R BS.1770 / EBU R128 ki te OGG, 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 whakapāpāhia te OGG o ahau i runga i te pūrere waka, i te iPod, i te Sonos rānei?

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 OGG codec i whakawhāititia ai mō ngā pūrere o tōmu ūnga. E whakawātea ana a OGG Vorbis i te MP3 i te mokatere tārua, ā, kāore he utu ātete, nā reira i whakaaetia e ngā mīhini kēmu me ngā pūmanawa pūtake-whenua kia nui ake.

He tūmataiti te tāku M4A i te wā o te tahuritanga ki OGG?

He — e whakarewaina ana ngā pūranga i whakarewaina M4A 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/.
