Tahuri AMR Tuhinga o mua MP3

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 MP3.

Ka taea e koe te tahuri i te MP3 ki AMR 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 MP3 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 MP3 mai i tērā, ka ārai katoa i te whakawhitinga rua. 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 ngaro te MP3: ko te tauira ā-hinengaro e whakakore ana i ngā auautanga kāore e taea e te oro te mōhio, i te nuinga o te wā i te 128 ki te 320 kbps.

Heoi, ā, he whiwhinga tūturu i runga i te AMR, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. MP3 e mau ana i te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi me te toi kāwai i roto i te kāwai, kia tika ai te pūranga pūoro me te kore e haere i te kāwai. Kāore he mea e whakawātea ana i te MP3 mō te ōritetanga — ko ngā pūrere waka, ngā pūrere ā-rohe, ngā DAP me ngā pūrere o te rua tekau tau e whakaako ana i a ia me te kore pātai.

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 MP3 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.

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. 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.

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 AMR 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 MP3. Kāore e hiahiatia kia tāpiri anō te hipanga tāpiritanga mō ia pūkete.

Ka tangohia ngā pūkete MP3 me ngā pūkete i whakarewatia i muri i tētahi matapihi takahuri poto. Kāore e tirotirohia, e tiritiritia, e whakaakona rānei i ngā pūkete o te kaiwhakaari. Ko ngā pātahitanga whakatere tūturu he wā-whāiti, ā, e hono ana ki tō tātau hautanga.
