WMV → MP3

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te MP3 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 MP3 mai i tērā, ka ārai katoa i te whakawhitinga rua. E mau ana a WMV i te Microsoft VC-1, WMV3 rānei me te oro WMA — e kore e āhei te pūrere i waho o te Windows ki te whakakōrero ā-iwi. 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 WMV, 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 anō, kia tika ai te pūranga pūoro me te kore e whakawhiti 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.

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.

DRM. He pūrere ā-roto o ngā pūranga WMV kua whakawaeheretia e te puna, te pūmanawa rānei i tukuna, ā, kāore e taea te whakawaehere i te oro whakawaeheretia e tētahi kaiwhakarere. Ko ngā mea katoa i whakawāteatia e koe, i whakakōrerotia, i hokona rānei me te kore parenga, ka whakawhiti i te tikanga; kāore e whakawāteatia te hoko ā-whakahaere. He tino tūkino te WMV: e hiahiatia ana e macOS, iOS, Android me ia kaiwhaiwhai ngā whakakōrero tuatoru, ā, ko ētahi pūranga WMV e mau ana i te DRM kāore e taea te tahuri.

Ko te bitrate tōtika mō te ngaro MP3 ko te 192 kbps, he mārama mō te pūoro. Ka taea e koe te whakawātea ki te 320 kbps (audiophile), 96-128 kbps rānei (rorohiko / podcast / pūranga iti ake). Ka puta te bitrate dropdown i roto i ngā kōwhiringa tiketike i mua i te kōwhiri i te tahuri.

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

Mā te pūmau, ā, — 48 kHz te oro i roto i tōmu WMV e noho ana 48 kHz i roto i te huaputa MP3. Mō te pūkōrero CD-burning, te pūkōrero rānei, ka taea e koe te whakawātea ki te 44.1 kHz mā te whakatata i te ōrite tauira; he mātauranga SoX-kitenga nui te tātai.

He — ka tangohia tētahi pūrākau o ngā pūranga WMV, ā, ka tangohia e tātau te oro i te āhua ōrite. Ka whiwhi ngā kaiwhakamaori Premium ki ngā kaimahi ā-tōtahi kē atu; i runga i te 50-file batch ko tēnei te rerekētanga i waenganui i ngā minu me ngā minu tekau.

Mēnā ka mau te WMV i te wāhanga, i te metadata rānei o te rerenga, ka tārua tātau i ngā āpure taitara / kaitapere / pūrākau ki roto i te MP3. Mēnā kāore, ka puta mai te MP3 kāore i te whakahuahua - ka whakamahia te kaiwhakawhanake tohu (Mp3tag, Picard) i muri i te whakahuahua mō te whakahuahua ā-whakahaere.

He tere te reo demux + encoding — i te nuinga o te 5 ki te 15% o te roanga pūtake. Ko te 1-ora WMV → MP3 e whakamutu ana i roto i te 3 ki te 9 minu i runga i te pūtautau paerewa; Ka whakaiti te whakatata Premium i tēnei i ngā mahi whakatōpū.

Kāore i tēnei utauta — ka tangohia te oro katoa hei MP3, kātahi ka whakamahia /oro-trim /, /oro-kuteru rānei hei whakaiti i te wāhanga. He tere ake te ara e rua-whakapae i te mahi whakakotahi, ā, ka hoatu ki a koe te mana tika o te taumata-whakapae.
