Question 2

He nui te āhuatanga kua ngaro i roto i tētahi pūranga MP2?

Accepted Answer

Ko te mea katoa i whakatau te kaikōrero taketake ki te whakakore, ā, kāore e taea te whakaora. MP2 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. He ngaro te MP2 engari he ngāwari ake te whakamahi i tētahi tātari pūtea i te MP3, i te nuinga o te wā e haere ana i te 192 ki te 384 kbps.

Question 3

He aha te pūmanawa pāohotanga me te tuhituhi e whakahau ana ki MP2?

Accepted Answer

Nā te mea i hangaia te mekameka katoa ki runga i a ia. Ko ngā pūnaha whakapāpāho, ngā utauta tuhi DVD me ngā pūnaha whakawhanake i whakapūtātia i te taha o tēnei āhua i te wā o tēnei wā, ā, kāore e whakapūtātia anō ngā pūrere me te wā o te ratonga whai hua e rua tekau tau. Ko ngā pūranga e puta mai ana i ēnei pūnaha ko te āhua o te pūnaha i hangaia hei tuku, ehara i te kōwhiringa i hangaia e tētahi tangata i tēnei wā. He tino kaha te MP2 ki ngā hapa ira, he ngāwari hoki te whakawaenga, ko te take i noho ai ngā mekameka whakawhitinga i runga i a ia i muri i te tae atu o te MP3.

Question 4

He aha te take i puta ai te tātau pūranga MP2 me te kore ingoa rererangi, mahi toi rānei?

Accepted Answer

Nā te mea kāore he wāhi e pupuri ai i a rātou te āhua. MP2 i tautuhia i te āhua o te oro, kāore he wāhi paerewa mō tētahi taitara, tētahi pūrākau, tētahi whakaahua papa rānei, nā reira ka hoki ngā kaiwhakaari ki te whakaatu i te ingoa faila. Ko te tahuri ki tētahi āhua tohu ko te mea e whakataki ana i tētahi puna — ka tuhituhitia ngā tohu i te wā o te tahuritanga, kaua i te whakaora, nō reira e tūmanako ana kia oti i tētahi mea kāore i mau i te pūtake. E hiahiatia ana e MP2 he nui ake te mokatere bit i te MP3, i te AAC rānei mō te āhuatanga ōrite, ā, kāore e mōhiotia ana ki te nuinga o ngā pūmanawa kaiwhakaari.

Question 5

Me tiaki tonu ahau i ngā pūranga hōu hei MP2?

Accepted Answer

Ahakoa rā, mēnā e hiahiatia ana e tētahi mea ki raro iho. Ka tuwhera tonu te āhua, ā, kāore he tūpatotanga mō te tahuri i tētahi pūranga kāore e take ana i ngā raruraru, engari kāore anō kia haere te utauta, te tōtika rānei. Mō tētahi mea hōu, kāore he utu tāpiri o te āhua o nāianei, ā, ka ārai i te porowhita o tēnei pātai i ētahi tau mai i tēnei wā.

Question 6

Ka taea e tētahi MP2 te mau i tētahi 5.1 ngāwari?

Accepted Answer

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.

Question 7

He mea hira rānei he toru tekau tau te MP2?

Accepted Answer

Ko te pakeketanga anake ehara i te raruraru — he maha ngā āhuahira mai i taua wā e pai tonu ana, i te mea kua tekau tau te whakatinana i a rātou. Ko te mea e hiahiatia ana ko te wā: he pūranga iti, he pūkaha iti, kāore he whatunga, me ngā āhuatanga kāore e hiahiatia ana e tētahi. Ki te āhua tonu o ēnei whakaaro, he pai te āhuahira. Ki te kore rātau, ko te take ki te tahuri. Ko te MP2 te MPEG-1 Audio Layer II, te apa i mua i te MP3, a, ka noho te paerewa oro mō te whakataka DVB me te DAB.

Question 8

He aha te take kāore e whakaata ana tētahi MP2 i roto i tōku whakataki?

Accepted Answer

Ko ngā kaiwhaiwhai e whakakōrero ana i tētahi rārangi poto, pūmau o ngā āhua reo, ā, ko MP2 i waho o ia, nā reira ka whakakōrerotia te faila i te wā o te whakapāpāhotanga, i te pūpāho rānei i te pūrongo o tētahi hapa. Ka whakatuwheratia e ngā pūmanawa papatahi me tētahi tautuhi codec whānui ake, kāore i te raruraru te whakatuwheratia. Mēnā me whakapāpāho te oro i runga i tētahi pouwāhi Wīwī, ko te tahuritanga te whakahōu — kāore he whakaritenga pūpāho e tāpiri ana i tētahi whakakōrero kāore i te whakapāpāhotia e te kaiwhaiwhai.

Question 9

He aha te bitrate me tahuri au i a ahau i a ahau MP2?

Accepted Answer

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 whakawaehere tuatahi.

Question 10

Ka huri te tahuri i te mokatere tauira o ahau MP2?

Accepted Answer

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.

Question 11

Ka taea e au te whakahōu te whakaroa i te wāhi i te whakarerekētanga o MP2?

Accepted Answer

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.

Question 12

Ka taea e au te tahuri i tētahi pūrākau katoa o ngā pūranga MP2 i roto i tētahi neke?

Accepted Answer

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.
