Tahuri AAC Tuhinga o mua Opus

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 OPUS.

Ka taea e koe te tahuri i te OPUS 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 OPUS 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 OPUS 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 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 pūrere me te orooro i roto i a ia, kaua ko te orooro i tōna ake. Ko taua apa tāpiri ko te wāhi e pupuritia ai te roanga, te taupū rapu me ngā metadata e tautuhia ana e te āhua, kia mōhio ai te kaitapere ki te roa o tētahi OPUS i mua i te whakakōrerotanga o tētahi tāruatanga kotahi, kaua e whakataki i te faila katoa hei kitea. Ko te tikanga hoki kāore te whakaroatanga i te whakatau i te mea e āhua nei: he maha ngā pūrere o tēnei momo e whakaaetia ana kia nui ake i tētahi momo orooro, ko te take e rua ai ngā pūkete OPUS ka rerekē te whanonga i te wā e kitea ana i waho.

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 te mōrearea tūturu anake e pā ana ki a ia. OPUS he pūkōrero hōu, ā, he pai ake i ngā mea tawhito i te bitrate ōrite — e kitea ana i raro iho i te 96 kbps — engari kāore e "whakapai"tia ana, ā, kāore e mōhiotia e te pūtake o te kaitapere, he pūpāpāho takitahi, he pouaka whakaata rānei i mua i te tīariari te faila. He pai ngā kaiwhaiwhai, ngā pūkoro me ngā rorohiko. Ka tirohia te pūrere tawhito rawa e hiahiatia ana hei tākaro, ā, kāore i te kōwhiri i runga i taua mea, ehara i te tau. Kua tata tonu te kore e tautokona e ngā pūrere takitahi te Opus — e whakaaro ana ki te whakatangitangi pūmanawa anake, ā, e tūmanako ana ngā pūkōrero waka kia whakakāhore i 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 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 OPUS. Kāore e hiahiatia kia tāpiri anō te hipanga tāpiritanga mō ia pūkete.

Ka tangohia ngā pūkete OPUS 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.
