Indlela yokuguqula WMA kuya AMR

Inyathelo 1: Ngenisa WMA amafayela usebenzisa inkinobho ngasentshonalanga noma ngoshicilela bese ushiya.

Inyathelo lesi-2: Chofoza inkinobho ethi 'Tshintsha' ukuqala ukuguqulwa.

Inyathelo 3: Qapha okuguqulwe AMR amafayela

WMA kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo we-WMA ube yi-AMR ngaphandle kokulahlekelwa yikhwalithi?

Layisha phezulu i-WMA file futhi umguquli wethu ukhetha i-AMR codec / bitrate combination efana ne-source. Injongo engalahleki (AMR = WAV / FLAC / ALAC) igcina yonke isampula; injongo elahlekile (AMR = MP3 / AAC / OGG) iphutha liyi-192 kbps ecacile kuma-earphones amaningi.

Yini i-bitrate i-AMR isebenzisayo?

Iphutha 192 kbps ku-lossy AMR; idlula-nge-lossless AMR. Idlula ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity ku-bitrates ephansi kakhulu.

Ingabe ukusuka ku-WMA kuya ku-AMR kuzonciphisa izinga lami lomsindo?

Uma WMA ilahlekelwa futhi AMR ayilahleki (isibonelo MP3 → WAV), i-AMR ihele alingcono kunale WMA — awukwazi ukubuyisela imininingwane esele ikhishwe. Uma WMA ilahlekelwa futhi AMR ayilahleki, cabanga ukuthi i-AMR codec izocindezela futhi; ku-192 kbps lokhu kucacile kunoma iyiphi ingxenye.

Ingabe i-WMA kuya ku-AMR iguqula igcina ID3 / amathegi wedatha yemeta?

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, i-album art ifundwa kusuka ku-WMA futhi ibhalwe ngaphakathi kwe-AMR container (lapho i-AMR format ixhasa izixhumanisi, okungukuthi zonke ezijwayelekile zikwenza).

Ingabe ngingenza i-batch yokuguqula ama-WMA amafayela amakhulu ku-AMR?

Yebo — khipha isibaya se-WMA amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ingabe i-AMR izogcina isilinganiso esifanayo sesampula njenge-WMA?

Ngokuzenzakalela yebo (48 kHz WMA → 48 kHz AMR). Uma ufuna ukuncipha kwesampula ukuze kusebenze (isibonelo 96 kHz → 44.1 kHz ukushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngesampula esezingeni eliphakeme.

Ingabe ngizolungisa umsindo ku-WMA kuya ku-AMR?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku-AMR output, lubeka inhloso -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-AMR izodlala ku-stereo yemoto yami / iPod / Sonos?

MP3 idlala emhlabeni wonke. AAC idlala ku Apple, Android, Sonos. FLAC idlala ku Sonos ne Android, ngaphezu kahle ku iPods edlule. WAV idlala konke kodwa kukhulu. Izinketho eziphezulu zifaka idivayisi imise izinhloso ezivamile.

Ingabe ihele lami WMA liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe WMA aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi.

Ithatha isikhathi esingakanani ukushintsha WMA yehora elilodwa kuya kuAMR?

I-codec efanayo iphinde i-mux: imizuzwana engu-10-30. Yenza kabusha i-codec eyahlukileyo: ngokuvamile 10-20% yesikhathi somthombo, ngakho-ke ihora elilodwa WMA → AMR liphele ngemizuzu engu-6-12.

Kungani ihele AMR likhulu / lihlanzekile kunalelo WMA?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule isinqumo sokujwayelekile. Uma ubona ushintsho lwezinga, umdlali wakho wesandi noma ithala lemithombo ingasebenzisa i-ReplayGain noma ukuguqulwa kwe-track-by-track ku-playback — hhayi nathi.

Ingabe ngiguqula WMA ukulayisha phezulu kwe-streaming ku-AMR?

Uma WMA i-download ayikhuselwanga (akukho DRM), yebo. Amafayela we-streaming abhalwe nge-DRM (Spotify, Apple Music) abhalwe nge-crypto ku-bit level futhi asikwazi ukuwaphatha. Ama-sources e-Bandcamp, SoundCloud download, nama-recordings asekhaya aguqulwa kahle.
