WMA iine kushaya simba nechinangwa, muASF chigaro, ne lossless uye mashoko-optimised zviuru izvo zvinoitika rarely. AMR i narrowband speech codec ichiita pakati pe4.75 ne12.2 kbps, ichifananidza munhu wechivanhu nechivanhu, asi kwete nezvose zvinotaurwa nezvokutaura.

Tenga WMA sekopi yakanyorwa, kana wozoitazve kunyorwa nekushandisa se Mp3tag kana MusicBrainz Picard. AMR inoravira ndangariro: 8 kHz bandwidth yake inoravira zvese zviri pamusoro pefoni frequencies, uye hapana mari yekudzokorora-kunyora zvinozoidzosera.

Chii chinoitika kune multichannel audio kana uchishandura WMA kuenda ku AMR?

Ichi chinovharwa pasi kusvika kustereo, nekuti AMR haina multichannel mode.

Chii zvaunogona kubvisa iwe pachako, kurodha pasi, kana kutenga pasina dziviriro inoshandura zvakajairika; chibvumirano chekutenga hachizove. WMA haitsigirwe zvakakwana chero kupi kunze Windows, uye vadiki WMA mafaera anogona kutakura DRM kuti anobata kushandurwa zvakakwana.

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.

Ndeipi bitrate iyo iyo AMR faira ichashandisa?

Zviri pachena kuti 192 kbps ndezvekuipa AMR; kusvikira kwasvika kwakanyanya AMR. Dzokera ku 320 kbps kana uchida kutamba kana 96 kbps kana uchida kutamba. Kusarudza kunochinja saizi yefaira neyekutaura; pasi pe 96 kbps, kuipa kunoonekwa mumimhanzi.

Kuenda kubva ku WMA kuenda ku AMR kunoderedza mhando yangu yeaudio?

Kana WMA iri nematambudziko uye AMR haina matambudziko (semuenzaniso MP3 → WAV), AMR haina matambudziko kupfuura WMA — haugone kudzosa ruzivo rwakaiswa pasi. Kana WMA iri nematambudziko uye AMR ine matambudziko, AMR codec inodzosera; pa192 kbps, iyo mhedzisiro inoratidza zvakajairika zvemukati.

Ichi chikonzero nei iyo WMA kusvika ku AMR converter inochengeta ID3 / metadata tags?

Yeah - zita, muimbi, album, gore, nhamba yemufananidzo, uye album art inoverenga kubva ku WMA container uye inonyora mu AMR container uko fomati inotsigira ma tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not. AMR i Adaptive Multi-Rate, 3GPP mutauro codec standardized for GSM mashoko kufona uye mobile voice recorders.

Ndinogona kushandura zviuru zve WMA mafaera kuita AMR?

Yeah - bvisa folder ye WMA mafaera uye isu tinozvigadzirisa zvakapararira. Premium ine akawanda akapararira vashandi uye hapana kumanikidza kwefaera, saka batch ye500-file inosvika muminetsi kupfuura makumi emakore.

I AMR ichachengeta iyo imwechete sampling rate se WMA?

Nekuzvimisikidza hapana — 48 kHz WMA inoramba 48 kHz mu AMR. Kana iwe uchida kushambadza pasi kuti ugone kuwirirana (96 kHz → 44.1 kHz kune CD yekunyora), sarudzo ye sampling-rate inoshandisa kushambadzazve kwemhando yepamusoro mune imwe encoding pass.

Ndinogona here kushandura kusimba kwezwi kana ndichishandura WMA kuenda ku AMR?

Yeah — loudness-normalize sarudzo inoshandisa ITU-R BS.1770 / EBU R128 normalization kune AMR, ichitarisa -14 LUFS (streaming standard) kana -16 LUFS (podcast standard). Zvakanakira kana uchibata mabhaisikopo akaomarara pazviyero zvakasiyana.
