M4A Tuhinga o mua AC3 Ngā Pātai Auau mō te Tahuritanga
He pēhea te tahuri i a au i te M4A oro ki te AC3 me te kore e ngaro te āhuatanga?
+
Whakataki i te M4A me te kaiwhakarere e kōwhiri ana i te AC3 ngā kōwhiringa codec / bitrate e ōrite ana ki te tātai pūtake. Ko te AC3 kore ngaro (WAV / FLAC / ALAC) e pupuri ana i ia tauira; ko te AC3 ngaro (MP3 / AAC / OGG / Opus) te pūmau ki te 192 kbps e mārama ana mō te nuinga o ngā ihirangi pūoro 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. 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.
He whakawhitinga te M4A ki te AC3 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 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.
Ka ora te whakarerekētanga M4A ki AC3 o nga taitara rererangi me te whakaahua o te pūrākau?
+
Kāore i te tīariari. M4A 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 M4A 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.
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 whakatata, i hoko rānei me te kore parenga, ka huri noa; kāore e hoko te hoko ā-kōrero. 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.
He aha te bitrate e whakamutu ana te AC3?
+
192 kbps te pūtake mō te ngaro AC3; whakawhitinga mō te kore ngaro AC3. Whakapae ki te 320 kbps mēnā e hiahiatia ana e koe te pūmautanga ngaro tino nui, 128 kbps mō te tuaritanga podcast-ki te rahi, 96 kbps rānei mō ngā pūtake reo- anake e nui ake ai te nui o te faila iti iho i te taipitopito o te whare karakia.
Ka whakaiti te haere mai i te M4A ki te AC3 i te āhua o te āhua o tōku oro?
+
Mēnā he ngaro te M4A (MP3, AAC) ā, he kore ngaro te AC3 (WAV, FLAC), kāore te AC3 i te pai ake i te M4A — kāore e taea e koe te whakaora i ngā mōhiohio kua whakakoretia e te codec ngaro M4A. Mēnā he kore ngaro te M4A ā, he ngaro te AC3, e tūmanako ana te AC3 whakakōrero kia whakawhāiti anō; i te 192 kbps kāore e mōhiotia te ngaro ki te nuinga o ngā oro.
E pupuri ana te M4A ki te AC3 kaiwhakarere i ngā tohu ID3 / metadata?
+
He — ko te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi, te toi pūrākau, te BPM, te whiwhinga whakahōu e ako ana mai i te M4A me te tuhi ki ngā āpure ōrite i runga i te AC3. ID3v2 (MP3), ngā kōrero Vorbis (OGG, FLAC), ngā ngota MP4 (AAC, M4A), RIFF INFO (WAV), iXML ngā wāhanga katoa o te mahere mārama. Ko te AC-3 ko Dolby Digital, te āhua o te āhua o te āhua i paerewa mō ngā pūrere, DVD, te pāpāhotanga ATSC me te kiriata i te tīmatanga o nga tau 1990.
Ka taea e au te tahuri-whakahaere i ngā rau o ngā pūranga M4A ki AC3?
+
He — Ka tangohia tētahi pūranga o ngā pūranga M4A ki roto, ā, ka tukatuka i a rātou. He nui ake ngā kaimahi taurite o te Premium, ā, kāore he tauine tauine-whakahaere, nā reira ka oti te rōpū 500-file i roto i ngā minu, kaua i ngā tekau minu. Ka tiakina te hanganga pūranga i te huaputa ZIP.
Ka pupuri te AC3 i te ōritetanga tauira pēnei i te M4A?
+
Mā te pūmau, ā, (48 kHz M4A e whakaputa ana i te 48 kHz AC3, he 44.1 kHz M4A e whakaputa ana i te 44.1 kHz AC3). Mō te ōritetanga tauwhāiti — hei tauira, te whakaiti i ngā māngai whare taupuni 96 kHz ki te 44.1 kHz AC3 mō te whakairo CD, te whakapiki rānei i te 22 kHz te karere reo ki te 44.1 kHz AC3 — ka hoatu te whakaiti o te ōrite tauira ki te whakarerekētanga āhua SOX-ki te āhua.
Ka taea e au te whakarerekē i te pūoro i roto i te hipanga M4A ki AC3?
+
He — 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 rānei (paerewa podcast), he uara rānei o te tangata. Ka whai hua ina tahuri ngā whakarerekētanga pūnoa me ngā taumata whakahaere rerekē ki tētahi pūrākau pūoro kotahi AC3.
Ka whakapāpāho te AC3 ki runga i tōku kaitiaki waka / iPod / Sonos / Kaikōrero Bluetooth?
+
Ka whakapāpāho te MP3 i ngā pūrere katoa i hangaia i ngā tau e 20 kua hipa. Ka whakapāho te AAC i runga i te Apple, i te nuinga o te Android, i te Sonos, i ngā pūrere o nāianei. Ka whakapāho te FLAC i runga i te Sonos me te Android o nāianei, he iti iho te pai i ngā iPods tawhito. Ka whakapāho te WAV i ngā mea katoa engari he nui te faila. Ka kōwhiria e te whakapāho-whāinga pūrere tētahi pūrere haumaru AC3 mō te pūnaha e tautuhia ana e koe. Ko te AC-3 te rererangi ā-rohe o ia kaiwhiwhi AV, te kaiwhakaari DVD me te whakakōrero TV, ko te take tonu e noho tonu ana te taketake o te whakawhitinga.
He tūmataiti te M4A o ahau i te wā o te tahuritanga?
+
He — e whakaata ana ngā pūranga M4A i whakarewaina i roto i ngā kaimahi motuhake, ā, ka tangohia i roto i ngā minu. Kāore anō tātau ki te whakataetae, ki te penapena, ki te tiritiri rānei i ngā ihirangi oro. Ka haere te pūtautau i runga i ngā pūrere e whakahaeretia ana e tātau i te mutunga ki te mutunga; kāore he ratonga tuatoru e whiwhi ana i tō koe.
M4A Ko te hōputu kōnae ororongo e te piri tata ki MP4. Ka tukuna he kohinga ororongo kounga teitei me te tautoko mo nga metadata, e pai ana mo nga momo tono.
