WMA haitsigirwe zvakakwana chero kupi kunze Windows, uye vadiki WMA mafaera anogona kutakura DRM kuti anobata kushandura 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 faira AMR inosvika nayo?

Zviri pachena kuti 192 kbps ndezvekunonoka AMR; kutevedzera kwe AMR pasina kunonoka. Gadzira 320 kbps kana iwe uchida kunonoka zvakanyanya, 128 kbps kune podcast yekugoverwa ine huremu, kana 96 kbps kune mashoko chete ayo faira rine hunhu kupfuura studio.

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

I WMA to AMR converter inochengeta ID3 / metadata tags?

Yeah - zita, muimbi, album, gore, track number, album art, BPM, replay-gain zvinoverenga kubva ku WMA container uye zvakanyorwa muzvinyorwa zvakaenzana pa AMR container. ID3v2 (MP3), Vorbis mashoko (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chunks zvese zvinoratidzwa zvakachena. AMR i Adaptive Multi-Rate, 3GPP mutauro codec standardized for GSM mashoko kufona uye mobile voice recorders.

Ndinogona here kushandura mamirioni e WMA mafaera kuita AMR?

Yeah — bvisa folder ye WMA mafaera uye isu tinozvigadzirisa zvakaenzana. Premium ine akawanda akaenzana maworkers uye hapana kumanikidza kwefile size, saka batch ye500-file inopera mumasekondi kupfuura maminetsi. Folder nharaunda inochengetwa muZIP output.

I AMR ichachengeta iyo imwechete sampling rate seWMA?

Kuti uwane kuvimbika kwakakodzera — semuenzaniso, kubvisa 96 kHz studio masters kusvika 44.1 kHz AMR kune CD kurodha, kana kubvisa 22 kHz voicemail kusvika 44.1 kHz AMR — iyo sample-rate dropdown inoshandisa SOX-style resampling ine mhando yepamusoro.

Ndinogona here kudzora kusimba kwezwi mu WMA kusvika ku AMR?

Yeah — loudness-normalize sarudzo inoshandisa ITU-R BS.1770 / EBU R128 normalization kune AMR output, ichitarisa -14 LUFS (streaming standard) kana -16 LUFS (podcast standard) kana chiyero chakakodzera. Inokosha kana uchishandura zvinyorwa zvakasiyana-siyana nemamwe masimba kuita imwe AMR playlist.
