Pa 192 kbps kana kupfuura, iyo mhinduro ichiri yakajeka kune vazhinji vanonzwa. Kana iwe uine master isina kushaya chero kupi, encoding the AAC kubva kune iyo inodzivirira double pass zvakakwana. AMR i narrowband speech codec ichiita pakati pe4.75 ne12.2 kbps, ichifananidza munhu wechivanhu nechivanhu, asi kwete nezvose zvinotaurwa nezvokutaura. AAC ine kushaya simba asi iri nyore kushandisa kupfuura MP3, uye inochengeta kusvika pa48 machannels zvakananga sezviri, kwete sezvaiita stereo.

Ndinogona here kuisa zita remutambi kana realbum paAAC?

Ndinoda, uye ndeimwe yechokwadi kubudirira kupfuura AMR, iyo haina kuchengeta chero chinhu. AAC inotakura zita, muimbi, album, gore, nhamba yemugwagwa uye inopinda mufananidzo wechidzitiro mubhokisi, saka library yemutauro inoisa zvakakwana pasina manual pass.

Nei mutauro wemutauro unonzwa sewevakadzi munguva iyi?

Nekuti imwe nzvimbo yacho inonzi codec yechitaura kupfuura codec yechirongwa chemuvhi. Inoratidza pfungwa dzevanhu uye inobvisa zvese zviri kunze kwebandwidth yefoni, izvo zvinokosha kana uchida kutumira meseji uye zvinokuvadza kana uchida kutumira chero chinhu chine mainstruments. Kuchinjana kwacho hakugone kudzosera mafrequencies akaipa — havana kunyorwa mukodzero yekutanga. AMR inoravira ndangariro: 8 kHz bandwidth yake inoravira zvese zviri pamusoro pefoni frequencies, uye hapana mari yekudzokorora-kunyora zvinozoidzosera.

Ndeipi bitrate iyo faira AAC inoshandisa?

Zviri pachena kuti 192 kbps ndezvekunonoka AAC; kutevedzera kwe AAC pasina kunonoka. Dzokera ku 320 kbps kune vanofarira mashoko kana 64-96 kbps kune mabhuku ekutaura (anoonekwa nemunhu anotaura, anowedzera saizi yefayela nehafu).

Kubva pa AMR kuenda pa AAC kunoderedza sei kunaka kwezwi rangu?

Kana AMR iri nehuwandu hwehuwandu uye AAC iri pasina huwandu hwehuwandu (e.g. MP3 → WAV), faira AAC harisi rakanaka kupfuura AMR — haugone kudzosa ruzivo rwakaiswa pasi. Kana AMR iri pasina hwando uye AAC iri nehuwandu hwehuwandu, fungidzira kuti codec AAC ichadzosera kumanikidza; pa192 kbps izvi zvinoratidzika kune zvimwe zvinhu.

I AMR to AAC converter inochengeta ID3 / metadata tags?

Yeah - zita, munyori, album, gore, nhamba yemufananidzo, nhamba yealbum, uye chikamu chezvinyorwa (zviri zvakakosha kune audiobooks) zvinoverenga kubva ku AMR uye zvakanyorwa muAAC chigaro apo AAC fomati inotsigira ma tags.

Ndinogona kushandura mazana e AMR mafaera kuita AAC?

Yeah - bvisa folder ye AMR mafaera uye isu tinozvigadzirisa zvakaenzana. Premium ine akawanda akaenzana maworkers uye hapana kumanikidza kwefaera, saka batch ye500-file inosvika mumasekondi kupfuura makumi emasekondi.

I AAC ichachengeta iyo imwechete sampling rate se AMR?

Zviri pachena kuti hapana (48 kHz AMR → 48 kHz AAC). Kana iwe uchida kushambadza pasi kuti zvive zvakaenzana (e. g. 96 kHz → 44.1 kHz for CD burning) iyo yakakwira sampling-rate sarudzo ichaita izvi nemhando yepamusoro yekushambadza.

Ndinogona here kudzora kusimba kwezwi mu AMR kusvika ku AAC?

Yeah — loudness-normalize sarudzo inoshandisa ITU-R BS.1770 / EBU R128 normalization kune AAC output, ichitarisa -14 LUFS (streaming standard), -16 LUFS (podcast standard), kana -23 LUFS (audiobook standard).

I AAC ichatamba pafoni yangu yefoni / iPod / audiobook app?

MP3 anotamba pasi rese. AAC anotamba paApple, vazhinji Android, Sonos. FLAC anotamba pa Sonos uye Android, zvakaipa pane vadiki iPods. M4B audiobooks kutamba nechitsauko kushanyira pa iOS Books, Audiobookshelf, uye Smart Audiobook Player.

Ndiani anochengeta AMR faira rangu panguva yekushandura?

Yeah — akakwira AMR mafaera anogadziriswa muzvirongwa zvakasiyana uye anogadziriswa mukati memasekondi. Tisingatamba, hatichengeti, kana kugovera zvemukati zvemutauro wechinyakare.
