Tahuri MP4 Tuhinga o mua 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 kore e taea te whakawhiti i te whakawhitinga rua katoa. 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. 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 MP4, 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.

He — he wāteatanga ā-pūmau te tahuritanga taketake MP4 → MP3 me te kore rāhuitanga. Ka tāpiri te utu ki ngā tepe nui ake i ia-kōkī, he nui ake ngā kaimahi whakatōpū, ā, ka tangohia ngā whakapuakitanga.

Ko ngā kāwanatanga wātea: tae atu ki te 100 MB ia MP4. Premium: i te nuinga o te 1 GB ia pūranga, i runga anō i te momo pūtake MP4. Ka wehea ngā pūranga nui ki ngā pūrere pāpāho-pāpāho ina whakaaetia e te āhua MP3.

Ka pupuri te tahuri i ngā mōhiohio katoa ka taea e MP4 me MP3 te tohu. Ko ngā āhuatanga ā-āhua kāore i tautokona e te āhua MP3 (hei tauira, ko ngā raraunga raupapa i roto i te huaputa raster, ngā tātai i roto i te huaputa kupu-pūnoa) ka whakarārangitia, ka whakawāteatia rānei — tirohia ngā tuhipoka ā-āhua i runga i te pātaka hua.

He — he maha ngā pūkete MP4 ki te rohe tāpiri, ā, ka whakatūtūtia rātau i te taha kotahi. He nui ake ngā kaimahi taurite o te Premium; i runga i te 50-file batch ko tēnei te rerekētanga i waenganui i ngā minu me ngā takirua.

Heoi — he urupare te UI, ā, ka haere te pūrere tahuri i te taha hoapā, kia whakatakia ai ngā pūrere pūkoro-kātahi ka whakatakia pēnei i ngā papamuri. iOS me ngā kaituhituhi tīrā Android (role kāmera, Papatono Files) ka mahi i te mutunga ki te mutunga.

Chrome, Firefox, Safari (15+), Edge, me Opera. Ka whakamahia e te kaiwhakarere te paerewa `<input type="file">`whakahauhau - kāore he WebAssembly, he PWA rānei - kia mahi ai ngā kaituhituhi tawhito.
