Tahuri WAV Tuhinga o mua M4A

Ko ētahi, ā, he tūturu — ko tēnei te aronga kotahi e whakawāteatia ai ngā mōhiohio. WAV e pupuri ana i ia tauira; M4A e whakakore ana i te mea e matapae ana tētahi tauira ā-hinengaro kāore e taea e koe te whakarongo. I te 192 kbps me te nui ake i taua matapae, he tino pai te mārama i runga i te nuinga o ngā rawa me te nuinga o ngā pūrere. Whakataki te WAV hei uho, nā te mea kāore e taea e koe te hoki ki a ia mai i te M4A. 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. Kei roto i te M4A te AAC i te nuinga o nga take, Apple Lossless rānei (ALAC) ina puta mai i tētahi tāruatanga kore.

Heoi, ā, he whiwhinga tūturu i runga i te WAV, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. M4A 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. Ka pupuri te M4A i ngā metadata āhua iTunes, ngā wāhanga me ngā mahi toi, ā, ko te āhua oro māori i runga i ngā pūrere Apple katoa.

Ko ngā pūkete wātea e whakawhāiti ana ki te 100 MB ia pūkete, ā, ka nui te haere o ngā pūtake WAV nā te mea ka mau te āhua i te nui o te pūkete i runga i te raraunga vitio. Ka whakatū te utu i te tauine. Mēnā ka wehea te pūkete ki ngā wāhanga tau i te take o te taumata āhua, ka whakatakatia rātou tahi, ā, ka whakaarotia hei mahi kotahi. He tino nui te WAV — tata ki te 10 MB ia minu i te āhuatanga CD — ā, he 4 GB te tauine o te āhua o te pūrākau, ā, kāore he wāhi mō ngā tohu tika.

Ko te pūmau ko te 192 kbps mō te ngaro M4A; whakawhitinga mō te kore ngaro M4A. Whakapae ki te 320 kbps mō te pūoro, 64-96 kbps rānei mō ngā pukapuka oro kōrero (whakaahua mō te reo, he haurua te rahi o te pūranga).

Mēnā he ngaro te WAV ā, he kore ngaro te M4A (hei tauira, MP3 → WAV), kāore te M4A faila i te pai ake i te WAV — kāore e taea e koe te whakaora i ngā mōhiohio kua whakawāteatia. Mēnā he kore ngaro te WAV ā, he ngaro te M4A, e tūmanako ana te M4A codec ki te whakawhāiti anō; i te 192 kbps he mārama tēnei mō te nuinga o ngā ihirangi.

He — ko te taitara, te kaitapere, te pūrākau, te tau, te tau, te tau rererangi, te toi pūrākau, me ngā tohu wāhanga (he hira mō ngā pukapuka oro) e ako ana mai i te WAV, ā, ka tuhituhi ki roto i te M4A tapawhā i te āhua o te M4A e tautoko ana i ngā tohu. Ko te hanganga pukapuka oro M4B e haere tata ana ki te M4B me te AAX → M4B huaputa.

He — Ka tangohia he pūrākau o ngā pūranga WAV ki roto, ā, ka whakamātautau mātou i a rātou i te whakarara. He nui ake ngā kaimahi whakatata o te Premium, ā, kāore he tauine tauine-whakahaere, nā reira ka oti te rōpū 500-file i roto i ngā minu, kaua ko ngā tekau minu.

Mā te pūmau, ā, (48 kHz WAV → 48 kHz M4A). Mēnā e hiahiatia ana e koe te whakaiti i te tauira mō te ōritetanga (hei tauira, 96 kHz → 44.1 kHz mō te pūngao CD) ka mahi tēnei te kōwhiringa tauira ā-whakapaina ki te whakawātea ā-whakapaina.

Hei — ka hoatu e te kōwhiringa pūnoa-pūnoa te pūnoa ITU-R BS.1770 / EBU R128 ki te huaputa M4A, e ūnga ana ki -14 LUFS (paerewa rerenga), -16 LUFS (paerewa podcast), -23 LUFS rānei (paerewa pukapuka oro). Ka whai hua ki te tahuri i ngā whakarerekētanga rerekē o ngā rerekētanga.

Ka whakapāpāho te MP3 i te ao whānui. Ka whakapāho te AAC i runga i te Apple, te nuinga o te Android, Sonos. Ka whakapāho te FLAC i runga i te Sonos me te Android, he iti iho te pai i ngā iPods tawhito. Ka whakapāho ngā pukapuka oro M4B me te whakaterenga wāhanga i runga i ngā pukapuka iOS, Audiobookshelf, me te kaiwhakaari Audiobook Smart. Kei roto i ngā kōwhiringa hōhonu ko ngā whakaritenga o mua o te pūrere.
