Kei roto i te M4A te oro AAC i roto i tētahi pūrere MP4, ā, ko te mea e whakamahia ana e iTunes me Apple Music mō ngā whakarerekētanga i whakawāteatia.

M4A Ngā Pātai Auau mō te Tahuritanga
He aha te M4A?
+
M4A is an audio-only MPEG-4 container format, often used for AAC-encoded audio.
He nui te āhuatanga kua ngaro i roto i tētahi pūranga M4A?
+
Ko te mea katoa i whakatau te kaikōrero taketake ki te whakakore, ā, kāore e taea te whakaora. M4A Ka whakawhāiti mā te tauira i te mea kāore e kitea e te roro — ngā oro mārō e noho ana i raro i ngā oro nui, ngā auautanga i te taha o te whakarongo — ā, ka tangohia tūturu. I tētahi bitrate ora kāore e taea te whakarongo ki te tata ki te katoa. Ko te mea kāore e taea te whakarerekē, nā reira ka tiaki i te āhua o nāianei ki tētahi āhua kore ngaro i te wā o nāianei i te whakaora i te taketake. 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 aha te pūoro i waho o te pūrongo M4A?
+
Nā te mea ka whakawaeheretia te pūrere ki te pūkoro, kaua ko te pūkaha, ā, ko tēnei te āhua e whakatinana ana e te pūkoro. Ko ngā pūkete reo, ngā pūoro whakaoro, me ngā tāruatanga karere katoa e puta mai ana i te kaikōrero ōrite, ko te take e tiritiri ana rātau i tētahi āhua kāore he pānga ki te mea e whakataki ana koe. Ka tākaro i runga i ngā pūrere Apple me te kore whakaaro, ā, e hiahiatia ana te tahuritanga i ētahi atu wāhi.
Ka ora te kaiwaiata, te pūrākau me te toi kāwai i runga i tōku M4A i te tahuritanga?
+
Ka mahi rātau i reira te āhua o te ūnga ūnga e tautuhi ana i a rātau. M4A e mau ana i ngā tohu me ngā toi whakawhāiti hei wāhanga o te faila, ā, he tārua i runga i ia āpure e mōhio ana te ūnga. Ko ngā ūnga kāore i te whakawhāiti te whakarerekētanga - i whakamāramatia i mua i te whakawhāiti he tūmanako noa iho, ā, kāore e pupuri i tētahi mea, nō reira ka tae mai tētahi pūranga i tahuritia i taua huarahi hei pakitara o ngā pūrere kāore i te ingoa.
Ka taea e tētahi M4A te mau i tētahi 5.1 ngāwari?
+
He — e whakahaere tika ana te āhuahanga i ngā pūkana neke atu i te rua, nā reira ka pupuri te whakakotahitanga ā-rohe i tōna whakaritenga pūkana, kaua e whakaroa ki te pūrere i te huarahi. Mēnā ka whakarongo rātau ki te whakaroa, ka whakawhirinaki ki te mutunga tawhiti: ka whakakōrerotia e te kaiwhiwhi ngā pūkana katoa, ka whakarōpūtia e te pūkoro i te wā whakataetae. Ka whakarerekētia ki tētahi āhuahira-pūrere anake ka noho tonu te whakaroa.
Ka whakapāpāho hāngai te M4A i roto i tētahi pou whetū?
+
He. M4A kei waenganui i ngā momo pūwhakaatu pūoro māori, nā reira ka taea te whakawātea ki tētahi huānga oro, ki tētahi pūpāpāho podcast rānei, ā, ka mahi i ngā wāhi katoa me te kore tāpiri, he pūkōrero rānei. Ka noho hei ūnga tānga haumaru, ā, ko te take o te tahuritanga o tētahi pūkete āhua kore ki tēnei hanga, ko te tikanga ko te huarahi poto rawa ki te whiwhi i te pūkōrero i runga i tētahi pae. Ka pupuri te M4A i ngā metadata āhua iTunes, ngā wāhanga me ngā mahi toi, ā, ko te āhua oro māori i runga i ngā pūrere Apple katoa.
Me hiahiatia anei e au he Mac hei mahi ki ngā pūranga M4A?
+
Kāore. I puta mai te āhua o Apple, ā, ko ōna pūrere me ngā pūmanawa e whakaputa ana i te pūmau, engari he pūnoa ngā pūranga anō, ā, ka pānui ki ētahi atu wāhi me te utauta tika. Ka puta te tahuri i tēnei wāhi i runga i te pūnaha, nā reira kāore he whakatū QuickTime, kāore he pūrere Apple, ā, kāore he pūrere codec-mātautau i roto i te tukanga.
He aha te bitrate me tahuri au i a ahau i a ahau M4A?
+
E ōrite ana ki te ūnga, ehara i te pūtake. Mō te pūoro, he mārama te 256 ki te 320 kbps ki te tata tonu ki ia kaimātau; mō te kōrero me ngā podcast, he nui te 96 ki te 128 kbps, ā, ka whakawātea anō te pūranga. Ko te whakawaehere i runga ake i te mokatere tāuru pūtake he mokowā whakawātea — he pono te tiaki i te oro i puta mai i tētahi whakawhitinga ngaro, ā, kāore e whakaora i tētahi mea i te whakawātea tuatahi.
E hiahiatia ana e te M4A he whakaaetanga whakawhiwhinga?
+
Kāore mō koe. Ko ngā pūkōrero e pā ana ki ngā pūtake ā-whakahaere, ā, ka whakaritea te whakaaetanga e ngā tāngata e whakarewa ana i ngā whakarerekētanga — te pūkoro, te whakataki, te pūnaha whakahaere — i mua i te tae atu o tētahi pūkōrero ki a koe. Ko te take o te āhua i ngā wāhi katoa o ngā pūrere, ko te take o te tīariari-kore-kore, ā, kāore e huri i te tahuritanga o tētahi pūkōrero kua whiwhi ki a koe.
Ka huri te tahuri i te mokatere tauira o ahau M4A?
+
Kāore, engari rawa ina tono koe. Ka pupuri tētahi tahuri i te mokatere pūtake — 48 kHz e noho ana ki te 48 kHz, 44.1 kHz e noho ana ki te 44.1 kHz — nā te mea he iti te utu o te hua ki te kore e hiahiatia. Ko ngā whakarerekētanga tūturu: e hiahiatia ana e ngā CD orooro te 44.1 kHz, kāore ētahi kaipāpāho pūrere tawhito e whakaae ana ki ētahi atu mea, ā, ko ngā pūwhitinga reo e hiahiatia ana he 16 kHz. Ka whakaritea te mokatere i roto i ēnei take, ā, ka waiho i te mea kē.
Ka taea e au te whakahōu te whakaroa i te wāhi i te whakarerekētanga o M4A?
+
Tata tonu ki te kore, ā, e mōhio ana te take: he tohu te whakaroatanga, i te wā e hanga ana ngā paerewa i roto mō tētahi hanga tauwhāiti. Ka whakaputaina e te whakahōutanga he faila ko te ingoa e whakapuakina ana he mea kāore i te tuku i ōna ihirangi, ā, ko te mea e whakatuwheratia ai, ka whakakāhore rānei i te faila, ka pāpāho rānei. Ko te whakawāteatanga whāiti kotahi ko ngā hanga e rua e tino ōrite ana i raro i ngā ingoa rerekē — ā, ahakoa he haumaru ake te whakaroanga tika i te whakahōutanga.
Ka taea e au te tahuri i tētahi pūrākau katoa o ngā pūranga M4A i roto i tētahi neke?
+
Me tētahi kāwanatanga, ā, — ka whakawātea rātau i te katoa, ā, ka whakawāteatia hei mahi kotahi, kaua e whakahaeretia tētahi i tētahi wā, me ngā whakaritenga ōrite e hoatu ana i te rōpū, ā, ka hoki ngā hua tahi. Ko ngā tahuritanga wātea e whakahaere ana i tētahi pūranga kotahi i tētahi wā (e rua ngā utauta whakakotahi); Ko te kaupapa utu te mea e whakawātea ai i te tukanga rōpū me te tepe nui ake i ia pūranga, e whakarerekē ana i tētahi pūranga katoa.
