M4A kuya WMA Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo M4A ube WMA ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele M4A futhi umguquli ukhetha WMA i-codec / i-bitrate ehambisanayo nomsuka. Isithembiso esingalahleki (WMA = WAV / FLAC / ALAC) sigcina yonke isampula; isithembiso esilahlekile (WMA = MP3 / AAC / OGG / Opus) simiselwe ku-192 kbps okucacile kuma-earphones amaningi.

Ihele WMA lisebenzisa i-bitrate enjani?

Iphutha 192 kbps ku WMA olahlekelwayo; dlula-nge- WMA ongalahlekelwanga. Nciphisa ku 320 kbps ku-audiophile, 256 kbps ku-high-quality music, noma 96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku fidelity ezwakalayo ku bitrates ephansi kakhulu.

Ingabe ukusuka ku M4A kuya ku WMA kuzonciphisa ubunjani bomsindo wami?

Uma M4A ilahlekelwa futhi WMA ayilahleki (isibonelo MP3 → WAV), ihele WMA alingcono kunaleli M4A - awukwazi ukubuyisela imininingwane eshaywe yi-encoding elahlekile yokuqala. Uma M4A ilahlekelwa futhi WMA ayilahleki, cabanga ukuthi i-WMA codec izocindezela futhi; ku-192 kbps lokhu kucacile kunoma iyiphi ingxenye.

Ingabe i-M4A kuya ku-WMA igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, i-album efakwe isithombe zifundwa kusuka ku M4A isitoreji futhi zibhalwe ku WMA isitoreji (noma yisiphi ifomu lomsindo elijwayelekile lixhasa iziphawuli). Iziphawuli zihlala zikhona ngisho uma i-codec engezansi ishintsha.

Ingabe ngingenza i-batch yokuguqula amahele angama-M4A abe WMA?

Yebo — susa isibaya se M4A 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 ivame ukuqedela imizuzwana endaweni yamaminithi ambalwa. Amathegi nesakhiwo sefolda zigcinwa.

Ingabe i-WMA izogcina isilinganiso esifanayo sesampula njenge-M4A?

Ngokuzenzakalela yebo — 48 kHz M4A → 48 kHz WMA, 96 kHz → 96 kHz. Uma ufuna ukusatshalalisa ngezansi ukuhambisana (96 kHz studio masters → 44.1 kHz for CD burning), isinqumo esiphezulu sesampula-rate sisebenzisa isampula esezingeni eliphakeme (libsoxr noma sox-equivalent) ngaphandle kokulalela i-alias.

Ingabe ngizolungisa umsindo ku-M4A kuya ku-WMA?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku WMA kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma kushintshaniswa i-batch i-library exhunywe i-tracks inezinga lokuphatha elihlukile.

Ingabe i-WMA izodlala kwi-stereo yemoto yami, i-iPod, noma i-Sonos?

I-MP3 idlala ngokugcwele kuwo wonke amadivayisi akhiwa eminyakeni edlule engu-20. I-AAC idlala ku-Apple, ku-Android, ne-Sonos. I-FLAC idlala ku-Sonos, ku-Android, nengxenye enkulu yemoto yamanje; isebenza kahle kakhulu kuma-iPods adala. I-WAV idlala kuwo wonke amadivayisi kodwa inamandla amakhulu. Ukhetho lwesisetshenziswa esisetshenzisiwe likhetha i-WMA codec ephephile kakhulu yesihluthulelo.

Ingabe ihele lami M4A liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu M4A aphathwa ngabasebenzi abahlukanisiwe futhi asuswa ngaphakathi kwemizuzu yokuqedwa. Asikwazi ukudlala, ukugcina, ukudlulisa, noma ukuhlanganisa okuqukethwe kwesandi. Ifasitela eligcwele lokugcinwa kwedatha libhalwe ku /privacy/.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-M4A libe WMA?

I-codec efanayo iphinde i-mux (isibonelo i-FLAC stream ngaphakathi kwebhokisi elinye lisetshenziswe kwezinye): imizuzwana engu-10-30. Yenza kabusha i-codec eyahlukileyo: ngokuvamile 10-20% yesikhathi somthombo, ngakho-ke ihora M4A → WMA liphele ngemizuzu engu-6-12.

Kungani ihele WMA likhulu noma lihlanzekile kunalelo M4A?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule ngokucacile ukhetho lokujwayelekile. Uma ubona isilinganiso soshintsho ngesikhathi sokudlala, umdlali wakho wesandi noma ithala lemithombo ingasebenzisa i-ReplayGain noma ukuguqulwa kwe-track-by-track ngokuya ngayo — leyo yi-player, hhayi i-pipeline yethu.

Ingabe ngiguqula M4A ukulayisha phezulu okuqhubekayo ku WMA?

Uma i-M4A ilayishwe phansi ingakhuselwanga (akukho DRM), yebo. Amafayela we-streaming abhalwe nge-DRM (i-Spotify ngaphandle kwe-inthanethi, i-Apple Music) abhalwe nge-crypto ku-byte level futhi singawasusa noma siwaqhubekele phambili. Ama-sources e-Bandcamp, SoundCloud, archive.org, nama-recordings asekhaya aguqulwa ngaphandle kwenkinga.

M4A

I-M4A ifomethi yefayela lomsindo ehlobene eduze ne-MP4. Inikeza ukucindezelwa komsindo kwekhwalithi ephezulu ngokusekelwa kwemethadatha, okuyenza ifaneleke izinhlelo zokusebenza ezihlukahlukene.

WMA

I-WMA (i-Windows Media Audio) ifomethi yokucindezela umsindo eyakhiwe yi-Microsoft. Ivamise ukusetshenziselwa ukusakaza kanye nezinsiza zomculo eziku-inthanethi.
