MP4 → AUDIO

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te AUDIO encoder e mahi ana 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 māngai kore ngaro i tētahi wāhi, ka whakakōrerotia te AUDIO mai i tērā, ka ārai katoa i te whakawhitinga rua. Tata tonu ki ia MP4 i te mohoao he ataata H.264 me te oro AAC; kei roto hoki i te kāwai he HEVC, AV1 me VP9. Ko ngā pūrere pūrere ki te MP3 i te 192 kbps, he mārama mō te nuinga o ngā rawa, ā, ka taea te whakaako i ia pūrere.

Heoi, ā, he whiwhinga tūturu i runga i te MP4, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. AUDIO e mau ana i te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi me te toi kāwai i roto i te kāwai anō, kia tika ai te pūranga pūoro me te kore e whakawhiti i te kāwai. Ko te kōwhiringa o te ūnga he āhuatanga tere rawa ina hiahiatia e koe te oro mai i tētahi pūranga, kāore he whakataunga pūkōrero hei mahi.

Ka whakaroatia ki raro ki te stereo, nā te mea kāore he āhuatanga ā-maha o AUDIO. 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 tūturu he ngaro, nō reira mēnā kāore te pūtake i te ngaro, ā, e hiahia ana koe ki te whakarerekē, ki te whakahaere rānei, ki te pātai mō WAV, FLAC rānei.

Ko te bitrate pūmau mō te ngaro AUDIO ko te 192 kbps, he mārama mō te pūoro. Ka taea e koe te whakahōu ki te 320 kbps (pūoro), 96-128 kbps rānei (whakaaho / podcast / pūranga iti ake). Ka puta te bitrate i roto i ngā kōwhiringa tiketike i mua i te kōwhiri i te tahuri.

Mēnā he kore ngaro te AUDIO (WAV, FLAC), ka tiakina ngā tauira katoa ki te tika. Mēnā he ngaro te AUDIO (MP3, AAC, OGG, Opus), ka whakawhāiti anō te codec AUDIO te pūtake oro — i te 192 kbps he mārama te hua mō te nuinga o ngā ihirangi. Ka haere te ngaro → kāore e whakaora ana i ngā taipitopito kua whakakoretia.

E whakawhirinaki ana — 48 kHz te oro i roto i tōna MP4 e noho ana 48 kHz i roto i te AUDIO huaputa. Mō te pūkōrero CD-burner, te pūkōrero rānei, ka taea e koe te whakamōhio ki te 44.1 kHz mā te whakaroa o te ōrite tauira; He mātauranga SoX-kitenga te tātai.

He — ka tangohia he pūrākau o ngā pūranga MP4, ā, ka tangohia e tātau te oro i te taha kotahi. Ka whiwhi ngā kaimahi utu nui ake i ngā kaimahi taha kotahi; i runga i te 50-file batch ko tēnei te rerekētanga i waenganui i ngā minu me ngā minu tekau.

Mēnā ka mau te MP4 i te wāhanga, i te metadata rānei o te rerenga, ka tārua tātau i ngā āpure taitara / kaitapere / pūranga ki roto i te AUDIO. Mēnā kāore, ka puta mai te AUDIO kāore i te whakahuahua - hoatu i tētahi kaiwhakawhanake tohu (Mp3tag, Picard) i muri i te whakahuahua mo te whakahuahua ā-wai.

He tere te whakahua reo + whakahua - i te nuinga o te 5 ki te 15% o te roanga pūtake. Ko te 1-ora MP4 → AUDIO e whakamutu ana i roto i te 3 ki te 9 min i runga i te pūtautau paerewa; Ka whakaiti ake te whakahua Premium i tēnei mō ngā mahi rōpū.

Kāore i roto i tēnei utauta — ka tangohia te oro katoa hei AUDIO, kātahi ka whakamahia te /oro-trim /, /oro-kutter / rānei hei whakaiti i te wāhanga. He tere ake te ara e rua-ki tētahi mahi whakakotahi, ā, ka hoatu ki a koe te mana tika o te taumata-whakamoho.

He — te tauira anō o te ātetetanga pēneia huringa: kaimahi motuhake, kāore he arotakenga tangata, he tango ā-pūmau i roto i ngā minu o te whakaotitanga. Ko te matapihi tauwhāiti o te tiakitanga i runga i te / ātetetanga/.
