Tahuri Opus 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 OPUS 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 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 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.

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.

Ka whakaroatia ki raro ki te stereo, nā te mea kāore he āhuatanga ā-maha o MP3. 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. Ko te MP3 e whakawāteatia ana e te AAC me te Opus i ia mokatere tātai, kāore e taea te rokiroki i ngā kanikani nui ake i te rua, ā, ka tāpiri tonutia he whakamutu ā-waenga iti.

Mai i te Wīwī, ā, ko te nuinga o te wā mai i ngā pūmanawa, ehara i te mea mai i ngā pūrere. I hangaia te OPUS mō te whakawhitiwhiti me ngā mekameka utauta pūtake-whenua, nō reira ka puta mai i roto i ngā rawa kēmu, ngā pūkete whakataki, ngā pūkōrero podcast me ētahi atu mea i hangaia e ngā tāngata kāore e hiahia ana ki tētahi kōrero ā-whakahaere. Ko te mea kāore e puta mai i roto ko ngā pūrere hiko, ko te take noa iho e hiahiatia ana e tētahi te tahuri i tētahi. 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.

He, kāore he āhuatanga e hiahiatia ana kia māharahara. He tūmatanui te whakaahuatanga, ka taea e tētahi te whakatinana i tētahi kaituhi, i tētahi kaituhi rānei me te kore e pānui, ā, kāore e taea e tētahi te huri i ēnei whakaritenga i muri mai - ko te take e puta ai i roto i ngā utauta pūtake-tūwhera, i ngā mīhini kēmu me ngā wāhi katoa ka whakamutua te kaupapa e te whakawhitinga ā-ara. Kāore te tahuri i te whakarerekētanga; ko ngā pūkete kua noho tika kētia e koe hei whakamahi.

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 OPUS 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.
