Opus Ngā Pātai Auau mō te Tahuritanga
He aha te Opus?
+
Opus is an open audio codec designed for interactive speech and music transmission.
He nui te āhuatanga kua ngaro i roto i tētahi pūranga Opus?
+
Ko te mea katoa i whakatau te kaikōrero taketake ki te whakakore, ā, kāore e taea te whakaora. Opus 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 Opus e whakawhānui ana i te 6 kbps mono speech ki te 510 kbps stereo music i roto i te rererangi ōrite, ā, ka huri noa i ngā āhuatanga.
He aha te nui o ngā ihirangi whatunga e tukua ana hei Opus?
+
Nā te mea i hangaia mō taua mahi: he ngātahi ngā pūkete iti, he tere te tīmatanga, kāore he tāpiri, kāore he whakaaetanga ki te māharahara. Mā tēnei e tino pai ai i te tuku, ā, kāore e tino mōhio ki ētahi atu mea — he utauta whakahua, he whare tākaro, he pūrere tawhito, ka whakakāhoretia i te nuinga o te wā. Ko te tahuri ki tētahi āhua take-whānui ko te mea e whakawātea ai i ngā ihirangi i whakawāteatia i te rārangi. Ko Opus te pūkōrero whakapeka pai rawa atu i ngā mokatere iti o te bitrate mā tētahi rohe mārama, ā, ka whakahaua e ia ngā tuhipoka reo WhatsApp, Discord me te WebRTC.
Ka ora te kaiwaiata, te pūrākau me te toi kāwai i runga i tōku Opus i te tahuritanga?
+
Ka mahi rātau i reira te āhua o te ūnga ūnga e tautuhi ana i a rātau. Opus 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 Opus 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.
He hōu rawa te Opus kia whānui te tautoko?
+
He iti iho i ia tau, engari he pono te rerekētanga. Ka tae tere te tautoko pūmanawa; ko te tautoko pūmārō anake e tae ana ki ngā pūrere hōu, ā, ko te tātari, te pouaka whakaata, te pūpāpāho rānei i mua i a koe ka taea te whakawhāiti. I te wāhi e tautokona ana, he pai ake te inenga i te āhua o te āhua e whakakapia ana, ko te take e tika ana te tahuri ki te whakawhiwhinga, ā, e tika ana te tahuri i te āhua o te ōritetanga.
Ka whakapāpāho hāngai te Opus i roto i tētahi pou whetū?
+
He. Opus 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.
He aha te bitrate me tahuri au i a ahau i a ahau Opus?
+
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.
Ko wai e whakahaere ana i te hanga Opus?
+
Kāore he tangata, i roto i te tikanga e hira ana: he tūmatanui te whakaahuatanga, he wātea noa iho te tuhituhi, ā, kāore e taea e te kamupene te huri i ngā whakaritenga i muri mai. Ko te take e puta ai i roto i ngā utauta pūtake tūwhera me ngā kaupapahere pūranga, i reira he āhua e whakahaeretia ana e te kaihokohoko, he tautoko hokohoko e whakawhiwhia ana ki te hokohoko — i te nuinga o te wā ko te āhua me te whakaahuatanga pai rawa me te pūrere pūrere pai rawa. Ko Opus he paerewa IETF mai i te tau 2012 nāna i whakakotahi te pūrere kōrero SILK o Skype me te pūrere pūoro CELT o Xiph ki roto i tētahi hoahoa.
Ka huri te tahuri i te mokatere tauira o ahau Opus?
+
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 Opus?
+
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 Opus 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.
