MKV → M4A

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te M4A 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 M4A mai i tērā, ka ārai katoa i te whakawhitinga rua. He pūāhua-pūāhua te MKV: H.264, HEVC, VP9 me te whakaaturanga AV1 e noho ai te AAC, FLAC, Opus, DTS, te oro Dolby rānei i roto i te pūranga kotahi. Kei roto i te M4A te AAC i te nuinga o nga take, Apple Lossless rānei (ALAC) ina puta mai i tētahi tāruatanga kore.

Heoi, ā, he whiwhinga tūturu i runga i te MKV, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. M4A 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. Ka pupuri te M4A i ngā metadata āhua iTunes, ngā wāhanga me ngā mahi toi, ā, ko te āhua oro māori i runga i ngā pūrere Apple katoa.

Ko te bitrate pūmau mō te ngaro M4A 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 M4A (WAV, FLAC), ka tiakina ngā tauira katoa ki te tika. Mēnā he ngaro te M4A (MP3, AAC, OGG, Opus), ka whakawhāiti anō te codec M4A 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 MKV e noho ana 48 kHz i roto i te M4A 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 MKV, 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 MKV i te wāhanga, i te metadata rānei o te rerenga, ka tārua tātau i ngā āpure taitara / kaitapere / pūranga ki roto i te M4A. Mēnā kāore, ka puta mai te M4A 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 MKV → M4A 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 M4A, 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/.

Tata tonu ki te tīpakonga rerekē i ngā wā katoa: MKV he maha ngā pūrere orooro, ā, i kōwhiria e te demuxer tētahi rererangi wātea, kore rānei. Ka whakamahia te kōwhiringa "pūrere orooro" hōhonu hei kōwhiri i te rererangi 0, 1, 2 mārama, ki te ūnga rānei i tētahi M4A kāwai e tautoko ana i te huaputa rererangi maha (FLAC, OGG).
