Ko te AMR he pūkōrero kōrero i whakaritea mō ngā pūkete reo me ngā whakarongo tātari, nā reira ka pōturi te pūoro i roto i a ia.

AMR Ngā Pātai Auau mō te Tahuritanga
He aha te AMR?
+
AMR (Adaptive Multi-Rate) is an audio format optimized for speech compression.
He nui te āhuatanga kua ngaro i roto i tētahi pūranga AMR?
+
Ko te mea katoa i whakatau te kaikōrero taketake ki te whakakore, ā, kāore e taea te whakaora. AMR 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. Ko te AMR he pūkōrero kōrero whāiti e haere ana i waenganui i te 4.75 me te 12.2 kbps, e tauira ana i te whakawhitinga reo tangata i te wā o te pūoro pūoro katoa.
He aha te āhua o te pūkete o te AMR i te whakatairite ki te pūoro?
+
Ko te mea kāore i te whakaritea kia mau i te pūoro. AMR He pūkōrero kōrero whāiti i hangaia mō ngā whatunga pūkoro, i whakaritea hei pupuri i ngā kupu e mōhiotia ana i tētahi mokatere tātari i inetia i roto i ngā kilobiti mati kotahi. Ka whakawāteatia ngā mea katoa i waho o te rohe o te reo tangata i te wā o te whakataki. Ka noho te tahuri ki tētahi āhua ā-rohe katoa i te whakataki i ngā wāhi katoa, engari kāore e taea te tāpiri anō i ngā auautanga kāore i te tauiratia. Ka whakangaromia e AMR te pūoro: ka tangohia e tōna 8 kHz te awhe katoa i runga ake i ngā auautanga tātari, ā, kāore he nui o te whakakōrerotanga e hoki ana ki a ia.
Mai i reira e puta mai ana ngā pūranga AMR?
+
Ko ngā pūnaha momo, ngā reo reo, ngā reo reo, ngā pūrere tawhito me te whakataki whakarongo - i ngā wāhi katoa me haere te oro i runga i tētahi kanikani whāiti, utu nui. E whakamāramatia ana e taua taonga tuku iho te take o te iti o ngā pūkete me te take o te pūoro i te āhua e pā ana. Ka whakarerekētia rātou ki ngā pūmanawa noa; kāore, kāore e taea, te tāpiri i te pono kāore i te whiwhi i te whakataki. Ko te AMR he Āhuatanga-maha-whakahaere, te pūkōrero kōrero 3GPP i whakaritea mō ngā whakarongo reo GSM me ngā pūkōrero reo poho.
Me tiaki tonu ahau i ngā pūranga hōu hei AMR?
+
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.
He aha te take kāore e whakaata ana tētahi AMR i roto i tōku whakataki?
+
Ko ngā kaiwhaiwhai e whakakōrero ana i tētahi rārangi poto, pūmau o ngā āhua reo, ā, ko AMR 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 papamuri me tētahi tautuhi codec whānui ake te whakatū i te raruraru. Mēnā me whakapāpāho te oro i runga i tētahi pouwāhi whatunga, ko te tahuritanga te whakatūtū — kāore he whakaritenga kaiwhakaari e tāpiri ana i tētahi whakakōrero kāore i te whakapāpāhotia e te kaiwhaiwhai.
He aha te bitrate me tahuri au i a ahau i a ahau AMR?
+
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 AMR 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 AMR?
+
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 AMR?
+
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.
He maha te wā e hiahiatia ana hei tahuri i tētahi AMR?
+
I te nuinga o te wā, he ngākati ngā pūkete iti, ā, ko ngā take e whai ana i te wā tūturu ko ērā e mahi ana i te mahi tūturu: he pūkete roa me whakakōrero anō i te rārangi i te rārangi, he tuhinga tātari i puta mai i te mōhiotanga ā-karaehe, he rōpū nui rānei. I te wā e whakarerekē ana tētahi tahuritanga, ka whakarōpū rānei i te raraunga tīariari, ka tere tonu, ahakoa te rahi o te pūkete, nā te mea kāore he mea whakakōrero.
He aha te huarahi pai ki te tukatuka AMR ngā kōnae?
