AMR → AIFF

Kāore, ā, e tika ana kia mārama: kāore e taea. Ko te AMR 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 AIFF 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 AIFF i tētahi whakatupuranga tuarua o ngā ahanoa i te wā e kawea atu ai. Ko AIFF te āhua o te whakawhitinga whare taupuni i runga i te macOS, e whakahaere tika ana i te metadata i te WAV noa iho, ā, ka tāurutia ki Logic me Pro Tools. Ka whakangaromia e AMR te pūoro: ka tangohia e tōna 8 kHz te awhe katoa i runga ake i ngā auautanga tātari, ā, kāore he nui o te whakakōrerotanga e hoki ana ki a ia.

Heoi, ā, he whiwhinga tūturu i runga i te AMR, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. AIFF 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. AMR e whakakōrerotia ana e ngā mea katoa, tae atu ki ngā wae o te karihi me ngā kaipāpāho tawhito; AIFF 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 karihi, he pūkōrero rānei te ūnga, he tautohe kaha mō te noho i runga i AMR. He nui tonu te AIFF ki te WAV me te tautoko iti iho i waho o te ao Apple, nō reira he kōwhiringa iti mō te tuaritanga.

Nā te mea he pūkōrero kōrero tētahi taha o te pūkōrero, ehara i te pūkōrero pūoro. E tauira ana i te pūkōrero tangata, ā, ka whakakore i ngā mea katoa i waho o te awhe whatunga, he pai mō te pūrongo reo, he tūkino hoki mō ngā mea katoa me ngā pūrere i roto. Kāore e taea te whakaora i ngā auautanga kāore i te ngaro - kāore anō kia waihangatia i te tuatahi.

192 kbps te pūtake mō te ngaro AIFF; whakawhitinga mō te kore ngaro AIFF. Whakapae ki te 320 kbps mēnā e hiahiatia ana e koe te pūmautanga ngaro tino nui, 128 kbps mō te tuaritanga podcast-ki te rahi, 96 kbps rānei mō ngā pūtake reo- anake e nui ake ai te nui o te faila iti iho i te taipitopito o te whare karakia.

Mēnā he ngaro te AMR (MP3, AAC) ā, he kore ngaro te AIFF (WAV, FLAC), kāore te AIFF i te pai ake i te AMR — kāore e taea e koe te whakaora i ngā mōhiohio kua whakakoretia e te codec ngaro AMR. Mēnā he kore ngaro te AMR ā, he ngaro te AIFF, e tūmanako ana te AIFF whakakōrero kia whakawhāiti anō; i te 192 kbps kāore e mōhiotia te ngaro ki te nuinga o ngā oro.

He — ko te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi, te toi pūrākau, te BPM, te whiwhinga whakahōu e ako ana mai i te AMR me te tuhi ki ngā āpure ōrite i runga i te AIFF. ID3v2 (MP3), ngā kōrero Vorbis (OGG, FLAC), ngā ngota MP4 (AAC, M4A), RIFF INFO (WAV), iXML ngā wāhanga katoa o te mahere mārama. Ko AIFF te Apple's Audio Interchange File Format mai i te tau 1988, i hangaia ki runga i te hoahoa porohita IFF ōrite ki te AVI's RIFF.

He — Ka tangohia tētahi pūranga o ngā pūranga AMR ki roto, ā, ka tukatuka i a rātou. He nui ake ngā kaimahi taurite o te Premium, ā, kāore he tauine tauine-whakahaere, nā reira ka oti te rōpū 500-file i roto i ngā minu, kaua i ngā tekau minu. Ka tiakina te hanganga pūranga i te huaputa ZIP.

Mā te pūmau, ā, (48 kHz AMR e whakaputa ana i te 48 kHz AIFF, he 44.1 kHz AMR e whakaputa ana i te 44.1 kHz AIFF). Mō te ōritetanga tauwhāiti — hei tauira, te whakaiti i ngā māngai whare taupuni 96 kHz ki te 44.1 kHz AIFF mō te whakairo CD, te whakapiki rānei i te 22 kHz te karere reo ki te 44.1 kHz AIFF — ka hoatu te whakaiti o te ōrite tauira ki te whakarerekētanga āhua SOX-ki te āhua.

He — ka hoatu e te kōwhiringa pūnoa-pūnoa te pūnoa ITU-R BS.1770 / EBU R128 ki te huaputa AIFF, e ūnga ana ki -14 LUFS (paerewa rerenga), -16 LUFS rānei (paerewa podcast), he uara rānei o te tangata. Ka whai hua ina tahuri ngā whakarerekētanga pūnoa me ngā taumata whakahaere rerekē ki tētahi pūrākau pūoro kotahi AIFF.

Ka whakapāpāho te MP3 i ngā pūrere katoa i hangaia i ngā tau e 20 kua hipa. Ka whakapāho te AAC i runga i te Apple, i te nuinga o te Android, i te Sonos, i ngā pūrere o nāianei. Ka whakapāho te FLAC i runga i te Sonos me te Android o nāianei, he iti iho te pai i ngā iPods tawhito. Ka whakapāho te WAV i ngā mea katoa engari he nui te faila. Ka kōwhiria e te whakapāho-whāinga pūrere tētahi pūrere haumaru AIFF mō te pūnaha e tautuhia ana e koe.
