WebM → WMA

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te WMA 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 WMA mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa. He whāiti te WebM: VP8, VP9 rānei te ataata (AV1 ināianei) me te Vorbis, te oro rānei, me ētahi atu. He ngaro te WMA i te pūmautanga, i roto i tētahi pūrere ASF, me ngā rerekētanga kore ngaro me ngā rerekētanga reo-whakahaere, ā, kāore i te kitea.

Heoi, ā, he whiwhinga tūturu i runga i te WebM, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. WMA 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. He pai ake te WMA i te whakawhāiti i ngā kaikōrero MP3 o nāianei, ā, ka taea te whakaako i te Windows Media Player me ngā pūrere PlaysForSure tahito.

I te nuinga o te wā kāore. WebM e whakakōrerotia ana e ngā mea katoa, tae atu ki ngā wae o te karihi me ngā kaipāpāho tawhito; WMA e hiahiatia ana he pūmanawa e mōhio ana ki te pūkōrero, ā, kāore i te nuinga o te wā e whai ana i ngā pūrere. Mēnā he pūkōrero karihi, he pūkōrero rānei te ūnga, he tautohe kaha mō te noho i runga i WebM. Kāore e tautokona e WMA te nuinga o ngā wāhi i waho o te Windows, ā, ka taea e ngā pūranga WMA tawhito te mau i te DRM e ārai ana i te tahuritanga katoa.

Mā te pūngao pūmau 0 (te pūrere oro tuatahi, i te nuinga o te wā ko te whakakotahitanga matua). Mēnā ka mau te WebM i ngā kōrero, ngā tāruatanga, ngā pūoro whakaahua rānei i runga i ngā pūrere tāpiri, ka whakaaetia e te kōwhiri "pūngao oro" whakahauahua kia kōwhiria e koe te 1, 2, 3... mārama. Ka whakaaturia te rārangi rererangi i te tirohanga tāuru, nā reira kāore e kōwhiria e koe te matapōkere.

Ko te WMA te mokatere bita tōtika tōtika ko te 192 kbps (mārō mō te pūoro ki te nuinga o ngā uaua). Whakapae ki te 320 kbps mō te huaputa audiophile, 96-128 kbps rānei mō te reo / podcast i reira ko te faila iti iho te arotahi. Ko ngā ūnga kore ngaro WMA (WAV, FLAC) ka whakakāhore i te whakaritenga bitrate me te pupuri i ia tauira.

Mēnā he kore ngaro te WMA hanga (WAV, FLAC, ALAC), ka tiakina ngā tauira taketake katoa. Mēnā he ngaro te WMA (MP3, AAC, OGG, Opus), ka whakawhāiti anō te codec — i te 192 kbps kāore e taea te whakarongo i te rerekētanga mō te nuinga o ngā ihirangi; i te 96 kbps ka taea e koe te whakarongo i ngā pūrere, i ngā pūrere rānei e whakangākau ana. Kāore he pānga ki tēnei te WebM kōpaka — ko ngā whakaritenga codec anake e pā ana.

Mā te pūmau, ā, — ka noho te oro 48 kHz WebM hei oro 48 kHz WMA, ka noho te 44.1 kHz hei oro 44.1 kHz. Mēnā e hiahiatia ana e koe te whakaiti hei ōritetanga (hei tauira, ko ngā māngai whare taiwhanga 96 kHz ki te 44.1 kHz CD-quality WMA) ka mahi tēnei te whakaititanga o te ōrite tauira me te whakarerekētanga o te āhuatanga tiketike.

He — ka tangohia he pūrākau o ngā pūranga WebM ki te rohe whakaata, ā, ka haere tonu tātau ki te whakawātea. He nui ake ngā kaimahi whakawātea a Premium; i runga i tētahi rōpū pūranga 100 (whakahaere pūoro-whitiāhua noa iho) ko tēnei te rerekētanga i waenganui i te 90 waeine me te 8 minu.

He tere ake te whakaterenga reo + transcode i te whakarerekētanga o te whakarerekētanga o te wikiō - i te nuinga o te 5-15% o te roanga pūtake. Ko te 1-ora WebM -> WMA e whakamutu ana i roto i ngā minu 3-9 i runga i te pūtautau. Mēnā ka ōrite te pūāhuatanga WMA ki te pūāhuatanga pūtake i roto i te WebM (tōtahi mō AAC i roto i MKV / MP4), he pūāhuatanga mārō, ā, ka haere i ngā takirua.

Mēnā ka rokiroki te WebM pūranga ki ngā raraunga meta (kaitapere, taitara, pūranga), ka tārua mai tātau i ēnei āpure ki te WMA kāwai e tautoko ana te hanga i ngā tohu. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC / M4A), RIFF INFO (WAV) kua tuhituhi katoatia. Kāore i whakawāteatia WebM ka whakaputaina i te WMA — hoatu Mp3tag, Picard rānei i muri i te kawemai hei whakarei.

He — ōrite te tauira ā-ringa me ia tahuritanga. Ko te pūtake WebM me te huaputa WMA e mahia ana i roto i ngā kaimahi motuhake, ā, ka tangohia i roto i ngā minu. Kāore anō kia whakataetae, ki te penapena, ki te tiritiri rānei i ngā ihirangi. Tirohia /privacy/.
