MP4 → FLAC

Kāore, ā, e tika ana kia mārama: kāore e taea. Ko te MP4 kua whakakoretia te taipitopito i te wā o tōna waehere taketake, ā, ko te whakaroa i te mea e noho ana i roto i tētahi FLAC kāore i te ngaro, ka pupuri tonu i taua mea - kāore anō. He maha ngā wā e nui ake ai te faila, ā, he ōrite ngā pūoro. He mahi tika tonu tēnei i mua i te whakarerekētanga, nā te mea kāore e tāpiri te FLAC i tētahi whakatupuranga tuarua o ngā ahanoa i te wā e kawea atu ai. Ka hoatu e FLAC ki a koe te pono WAV i te haurua o te rahi, me ngā tohu metadata tika me ngā toi whakarākei, ko te take e whakahaeretia ai e ia ngā pūranga pūoro kore. Ko MP4 anake e tautoko ana i tētahi hanga tuhituhi ā-whānui (mov_text), ā, kāore te oro-maha i te whakawhirinaki i waho o ngā kaiwhakaari papatahi.

Heoi, ā, he whiwhinga tūturu i runga i te MP4, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. FLAC 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.

I te nuinga o te wā kāore. MP4 e whakakōrerotia ana e ngā mea katoa, tae atu ki ngā wae o te waka me ngā kaiwhakaari pakeke; FLAC 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 waka, he kaiwhakaari whakarerekē rānei te ūnga, he tautohe kaha mō te noho i runga i MP4. He maha tonu ngā wā e nui ake ana te FLAC i tētahi pūkete ngaro pai, ā, ko te pūnaha āhua o Apple i tāpiri anake i te tautoko i tēnei wā, ā, i te pōharatanga.

Ko te bitrate pūmau mō te ngaro FLAC ko te 192 kbps, he mārama mō te pūoro. Ka taea e koe te whakahōu ki te 320 kbps (pūoro), 96-128 kbps rānei (whakaaho / podcast / pūranga iti ake). Ka puta te bitrate i roto i ngā kōwhiringa tiketike i mua i te kōwhiri i te tahuri.

Mēnā he kore ngaro te FLAC (WAV, FLAC), ka tiakina ngā tauira katoa ki te tika. Mēnā he ngaro te FLAC (MP3, AAC, OGG, Opus), ka whakawhāiti anō te codec FLAC te pūtake oro — i te 192 kbps he mārama te hua mō te nuinga o ngā ihirangi. Ka haere te ngaro → kāore e whakaora ana i ngā taipitopito kua whakakoretia. Ka whakamahia e FLAC te matapae paerangi me te whakawaehere Rice hei tae ki te 50–60% o te rahi taketake i te wā e whakawaehere ana ki te PCM ōrite-titi.

E whakawhirinaki ana — 48 kHz te oro i roto i tōna MP4 e noho ana 48 kHz i roto i te FLAC huaputa. Mō te pūkōrero CD-burner, te pūkōrero rānei, ka taea e koe te whakamōhio ki te 44.1 kHz mā te whakaroa o te ōrite tauira; He mātauranga SoX-kitenga te tātai.

He — ka tangohia he pūrākau o ngā pūranga MP4, ā, ka tangohia e tātau te oro i te taha kotahi. Ka whiwhi ngā kaimahi utu nui ake i ngā kaimahi taha kotahi; i runga i te 50-file batch ko tēnei te rerekētanga i waenganui i ngā minu me ngā minu tekau.

Mēnā ka mau te MP4 i te wāhanga, i te metadata rānei o te rerenga, ka tārua tātau i ngā āpure taitara / kaitapere / pūranga ki roto i te FLAC. Mēnā kāore, ka puta mai te FLAC kāore i te whakahuahua - hoatu i tētahi kaiwhakawhanake tohu (Mp3tag, Picard) i muri i te whakahuahua mo te whakahuahua ā-wai.

He tere te whakahua reo + whakahua - i te nuinga o te 5 ki te 15% o te roanga pūtake. Ko te 1-ora MP4 → FLAC e whakamutu ana i roto i te 3 ki te 9 min i runga i te pūtautau paerewa; Ka whakaiti ake te whakahua Premium i tēnei mō ngā mahi rōpū.

Kāore i roto i tēnei utauta — ka tangohia te oro katoa hei FLAC, kātahi ka whakamahia te /oro-trim /, /oro-kutter / rānei hei whakaiti i te wāhanga. He tere ake te ara e rua-ki tētahi mahi whakakotahi, ā, ka hoatu ki a koe te mana tika o te taumata-whakamoho.

He — te tauira anō o te ātetetanga pēneia huringa: kaimahi motuhake, kāore he arotakenga tangata, he tango ā-pūmau i roto i ngā minu o te whakaotitanga. Ko te matapihi tauwhāiti o te tiakitanga i runga i te / ātetetanga/.
