Tahuri WAV Tuhinga o mua MP4

E kōwhiri ana e koe tēnei, nā te mea kāore he whakaahua i roto i te oro. Ko te pūmau he whakarārangi momo ngaru takoto, ā, ka taea e koe te whakarato i tētahi whakaahua tūturu i reira - te toi whakawhāiti, he kāri taitara, he whakaahua - e pupuritia ana mō te roanga katoa. Ko te mea e whakataki ana te faila ki ngā papatono whakaata anake kāore e whakaaetia ana he whakataki oro. Ko te WAV he pūrere oro i runga i te Microsoft me IBM RIFF mai i te tau 1991, ā, ko te mea tata tonu ki ngā whakawhitinga oro me ngā DAW e tuhi ana i runga i te pūkete. Ko MP4 te ūnga whakawhiwhinga tino haumaru rawa - ko ia whatunga, kaitiaki, pāpāho, kaiwhakawhanake me te Smart TV i hangaia i roto i te tekau tau i muri mai e whakawhiwhia ana ki te kore pūmanawa tāpiri.

Ki te mea e whakaae ana te MP4 kōwae ki te pūtake o te pūoko oro, ka tāruatia te rerenga i te kore e pā ki te āhua o te bit-identical. Ki te kore, ka whakakōrerotia te oro kotahi ki tētahi mea e whakaae ana te MP4, i te mokatere bit e ōrite ana ki te pūtake kia iti iho ai te utu o te whakawhitinga tuarua. Ko te tikanga ka rokiroki te WAV i te PCM kāore i whakawhāititia - ka pupuritia tika ia tauira, i te mokowā o te hōhonu me te mokatere tauira i tangohia. 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.

I te nuinga o te wā, nā te mea e tūmanako ana ngā kāwai ataata ki tētahi rererangi oronga whakawhāiti, ā, kāore e whakaae te nuinga o ngā pūpāpāho ki te PCM mārō i roto i tētahi. Ka whakakōrerotia te oronga kotahi, i te bitrate tiketike kia kore ai te ngaro, ā, ka noho kore e pā ki te WAV kore ngaro i tōna taha. Whakawhanake: ka noho tonu te matua, ā, ko te MP4 he tārua whakawhiwhinga. Ko te WAV te āhua tika mō te whakahua, te whakahauhau me te pūranga, nā te mea ka taea te whakakōrero anō i ētahi wā me te kore e whakatōpū i ngā ahanoa.

He iti iho te nui ake, mēnā e whakamahia ana e koe te whakaahua tūturu pūmau. Ko te tāruatanga o tētahi tāruatanga kotahi ki te kore e tata ki te roa katoa nā te mea he ōrite ia tāruatanga ki te whakamutunga, nā reira ka whakahaeretia te faila e te rererangi oro. Mā te kōwhiri i tētahi āhua haurangi whakairoiro i te wāhi e tāpiri ai te raraunga ataata tūturu, ā, ka taea te rua, te toru rānei te hua.

He — MP4 e mau tika ana te oro-maha, nā reira ka noho te 5.1 he 5.1 me te papatono kanikani i te āhua nei, kaua e whakaroa ki te stereo. E pā ana tēnei mēnā kua whakaritea te faila mō tētahi kaiwhiwhi kiriata kāinga, kaua ko tētahi tātari, ka whakawātea i te wā whakataetae.

He — he wāteatanga ā-pūmau te tahuritanga taketake WAV → MP4 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 WAV. Premium: i te nuinga o te 1 GB ia pūranga, i runga anō i te momo pūtake WAV. Ka wehea ngā pūranga nui ki ngā pūrere pāpāho-pāpāho ina whakaaetia e te āhua MP4.

Ka pupuri te tahuri i ngā mōhiohio katoa ka taea e WAV me MP4 te tohu. Ko ngā āhuatanga ā-āhua kāore i tautokona e te āhua MP4 (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 WAV 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.
