Tahuri AAC 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 AAC 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. He ngaro te AAC engari he pai ake te pai ake i te MP3, ā, ka whakahaeretia tae atu ki ngā kanikani 48 māori i te whakatū i runga i tētahi hoahoa ira. 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.

Kāore i te tīariari. AAC e mau ana i tētahi kōpaka metadata tika, engari AMR kāore he wāhi paerewa mō te kaitapere, pūrākau, tau rererangi, toi rānei, nā reira ka whakawāteatia ngā tohu i te kore e whakawāteatia. Whakataki te AAC hei tārua tohu, whakahōu rānei i muri mai me tētahi utauta pēnei i te Mp3tag, MusicBrainz Picard rānei. 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.

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.

Nā te mea ko te mea e whakaputaina ana e te whakakōrero pūrere i runga i te pūrere. Ko ngā kōrero reo, ngā whakataki mata, me te whakataki oro o tētahi mea i whakairotia i runga i te pūkoro e puta mai ana hei AAC kāore e taea e tētahi te kōwhiri, ko te take he maha ngā pūkete e tae ana ki roto, ā, he aha te pai ake o te āhuatanga i te nuinga o te rahi o te pūkete. Kāore he mea e whakakore ana i te tahuri; ko te tikanga anake o te pūtake kua whakakōrerotia tētahi wā, e tētahi pūkoro i whakawhāititia mo te ora pūkoro, kaua mo te pono. Ko te AAC he waehere oropi whakahauhau, i paerewa i te tau kotahi mano e 1997 hei MPEG-2 Part 7, ā, i hangaia mārama hei whakakapi i te MP3.

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.

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 AAC 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.
