Tahuri AC3 Tuhinga o mua AMR

Mā te pūmau, ā, ka noho te pūmau, ka mau te mokatere tauira taketake (44.1 kHz, 48 kHz, ērā atu mea) ki te huaputa AMR.

Ka taea e koe te tahuri i te AMR ki AC3 i tēnei pae. Mēnā he ngaro te āhua o tētahi o ngā āhua e pā ana, kāore te haerenga paetata i te iti-whakatika, ahakoa he tata tonu, he mārama rānei.

Ko ngā whakaritenga pūmau e ūnga ana ki te mātauranga pāohotanga / tīwae - e ōrite ana ki te pūtake mō te nuinga o ngā kaitirotiro. Mō te whakamahinga pūranga, kōwhiria te kōwhiringa mātauranga tiketike rawa i roto i ngā whakaritenga tahuri.

Heoi, ā, e whai tikanga ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ka mahi te AMR encoder 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 matua kore ngaro i tētahi wāhi, ka whakakōrerotia te AMR mai i tērā, ka ārai katoa i te whakawhitinga rua. 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. 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 nekehanga mārō o ngā tāruatanga oro whakahuahua kāore he kāwai e whakaroa ana i a rātou. Ko te take e taea ai te hono i ngā pūranga e rua AMR mā te whakatū i tētahi i muri i tētahi, ā, ko te take e taea ai ngā mea katoa i waho o te oro - he roa, he pūtātau rapu, te toi kāwai - me whakatū i te āhua o te tikanga, kaua ko tētahi wāhanga o te āhua, nō reira me whakaako te kaiwhakaari i te faila katoa hei mahi i te roa o te wā. E pā ana ki te mea ngāwari rawa ka taea te kiia he pūranga oro, ko te take tonu e puta ai i roto i ētahi atu kāwai i te nuinga o te wā i te āhua o tōna ake.

Ka whakaroatia ki raro ki te stereo, nā te mea kāore he āhuatanga ā-maha o AMR. Ka whakamahia e te whakarōpūtanga ngā taupū paerewa kia mārama ai te whakawhitinga pūwāhi-pūwāhi, ā, ka whakarōpūtia ngā rohe i te taumata iti iho. Ka ngaro te mea katoa i runga i te tauwāhi pūwāhi motuhake ina puta mai. 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.

Kāore tētahi e hiahiatia ana kia whakaaro koe. Ko te pūkōrero e taupokitia ana e ngā pūtake whakawhiwhinga, ā, ka whakaritea te whakaaetanga e te tangata e whakarewa ana i te whakarerekētanga - te pūkoro, te whakataki, te pūnaha whakahaere - i mua i te tae atu o te pūkōrero ki a koe. Ko te take o te āhua i ngā wāhi katoa i roto i ngā pūrere, ā, ko te take i hangaia ai ngā whirinoa kore utu. Kāore e huri i te tahuritanga o tētahi pūkōrero kua whaitia e koe, ā, he pātai ora anake mēnā e whakarewa ana e koe tētahi whakarerekētanga.

Nā te mea he pūkōrero kōrero tētahi taha o te pūkōrero pūoro, kaua ko tētahi pūkōrero pūoro. Ka tauiratia e ia te āhua o te āhua o te tangata me te whakakore i ngā mea katoa i waho o te awhe whatunga, he pai mō te pūrongo reo, he tūkino hoki mō ngā mea katoa me ngā pūrere i roto. Kāore e taea te whakaora i ngā auautanga kāore i te ngaro - kāore anō kia waihangatia i te tuatahi. 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.

Mō tētahi wāhanga motuhake o ngā pūmanawa, ngā pūrere rānei kāore e whakaae ana ki tētahi atu — he āhuatanga tūturu, ā, ko te take pai anake. AMR e pā ana ki tētahi whakatupuranga o mua: ko ngā pūkōrero hōu ake e mahi ana i te mahi ōrite i ngā rahi iti iho, ka whakawātea ngā kaiwhakaari take-whānui i te tautoko mō te mea, kaua e tāpiri, ā, kāore he mea hōu e hangaia ana i te taha. Mēnā e hiahiatia ana tētahi mea i roto i te mekameka, ka tahuri, ka pupuri i te taketake hei māngai. Mēnā kāore he mea, ka tahuri i te taha.

Ko ngā tāurunga ā-whakaahua kua whakawhāititia i te pūtake nui; ko ngā pūkete wātea i whakaingoatia e whiwhi ana i tētahi taumata tiketike ake, ā, kāore he tepe-tokotahi o ngā pūkete Pro. Ko te pūmahara whakahura te āhua o te āhua o te āhua o te whakawhāititanga i mua i te whakawhāititanga o tātau tauwāhi pāpāho.

He. He maha ngā pūkete AC3 i roto i tētahi tāpiritanga — ka whakamātautau te whakarerekē i a rātou i te taha kotahi, ā, ka hoki mai i tētahi ZIP o ngā hua AMR. Kāore e hiahiatia kia tāpiri anō te hipanga tāpiritanga mō ia pūkete.
