He pēhea te tahuri i a au i te AMR oro ki te AAC me te kore e ngaro te āhuatanga?

Whakataki i te AMR me te kaiwhakarere e kōwhiri ana i te AAC ngā kōwhiringa codec / bitrate e ōrite ana ki te tātai pūtake. Ko te AAC kore ngaro (WAV / FLAC / ALAC) e pupuri ana i ia tauira; ko te AAC ngaro (MP3 / AAC / OGG / Opus) te pūmau ki te 192 kbps e mārama ana mō te nuinga o ngā ihirangi pūoro katoa. Ko te AMR he pūkōrero kōrero whāiti e haere ana i waenganui i te 4.75 me te 12.2 kbps, e tauira ana i te whakawhitinga reo tangata i te wā o te pūoro pūoro katoa. He ngaro te AAC engari he pai ake te pai ake i te MP3, ā, ka whakahaeretia tae atu ki ngā kanikani 48 māori i te whakatū i runga i tētahi hoahoa ira.

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te AAC 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 AAC mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa.

Ka taea e au te tohu i te AAC me ngā mōhiohio kaiwaiata me te pūrākau?

Heoi, ā, he whiwhinga tūturu i runga i te AMR, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. AAC 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. He tino pai ake te AAC i te MP3 i raro i te 128 kbps, ā, ko te aho pūmau i roto i te MP4, YouTube, Apple Music me te pāpāhotanga.

He aha te āhua o te pūoro i roto i tēnei tahuritanga?

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. 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.

He aha te bitrate e whakamutu ana te AAC?

192 kbps te pūtake mō te ngaro AAC; whakawhitinga mō te kore ngaro AAC. 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.

Ka whakaiti te haere mai i te AMR ki te AAC i te āhua o te āhua o tōku oro?

Mēnā he kore ngaro te AMR ā, he ngaro te AAC, e tūmanako ana te AAC whakakōrero kia whakawhāiti anō; i te 192 kbps kāore e mōhiotia te ngaro ki te nuinga o ngā oro.

E pupuri ana te AMR ki te AAC kaiwhakarere i ngā tohu ID3 / metadata?

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 AAC. ID3v2 (MP3), ngā kōrero Vorbis (OGG, FLAC), ngā ngota MP4 (AAC, M4A), RIFF INFO (WAV), iXML ngā wāhanga katoa o te mahere mārama.

Ka pupuri te AAC i te ōritetanga tauira pēnei i te AMR?

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

Ka taea e au te whakarerekē i te pūoro i roto i te hipanga AMR ki AAC?

He — ka hoatu e te kōwhiringa pūnoa-pūnoa te pūnoa ITU-R BS.1770 / EBU R128 ki te huaputa AAC, 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 AAC.

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 AAC mō te pūnaha e tautuhia ana e koe. He āhua ā-patent te AAC, ā, he tokomaha nga kaiwhakaari tawhito e whakakāhore ana i a ia i te wāhi e whakaae ana rātau ki te MP3.
