WebM → 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 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. 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 WebM, 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 tētahi mea 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.

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 AUDIO 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 AUDIO (WAV, FLAC) ka whakakāhore i te whakaritenga bitrate me te pupuri i ia tauira.

Mēnā he kore ngaro te AUDIO hanga (WAV, FLAC, ALAC), ka tiakina ngā tauira taketake katoa. Mēnā he ngaro te AUDIO (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 AUDIO, 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 AUDIO) 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 -> AUDIO e whakamutu ana i roto i ngā minu 3-9 i runga i te pūtautau. Mēnā ka ōrite te pūāhuatanga AUDIO 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 AUDIO 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 AUDIO — 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 AUDIO 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/.
