WMA kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo WMA ube AAC ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele WMA futhi umguquli ukhetha i-AAC codec ne-bitrate ukufana nomsuka. Ukungabi naphutha AAC (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho AAC (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi. I-WMA ilahlekelwa yiphutha, ebhokisini le-ASF, nge-lossless nezwi elingcono kakhulu elivame ukutholakala. I-AAC ilahlekelwa yizinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design.

Ingabe ukushintsha WMA kuya ku AAC kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AAC encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-AAC kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

Kungani ezinye ze WMA zefayela lami zingaguqulwa?

DRM. Iqoqo elincane lamafayela WMA libhalwe ngokufihlakele yisitolo noma isofthiwe eyenza, futhi umsindo obhalwe ngokufihlakele awukwazi ukukhishwa yinoma iyiphi i-convertor. Noma yini oyidingayo, orekhodiwe, noma othengiswe ngaphandle kokuvikelwa uguqulwa ngokuvamile; ukuthengiswa kwelayisense akuzokwenza. WMA ayixhaswanga cishe kuwo wonke indawo ngaphandle Windows, futhi WMA older amafayela angaba nesi DRM ukuthi ivala ukuguqulwa ngokuphelele.

Yini i-bitrate ongayisebenzisa ihele elivela ku-AAC?

Iphutha ngu-192 kbps ku AAC olahlekelwayo; ukudluliswa-kwe- AAC okungalahleki. Nciphisa ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kuka-96 kbps olahlekelwayo, ama-artefacts abonakala emculo.

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

Uma WMA ilahlekelwa futhi AAC ayilahleki (isibonelo MP3 → WAV), AAC ayingcono kuna WMA — awukwazi ukubuyisela imininingwane elahlekile. Uma WMA ilahlekelwa futhi AAC ayilahleki, i-AAC codec icindezela futhi; ku-192 kbps imiphumela icacile kunoma iyiphi ingxenye.

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

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku WMA isitoreji futhi zibhalwe ku AAC isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi. I-AAC iyi-Advanced Audio Coding, ejwayelekile ngo-1997 njenge-MPEG-2 Part 7 futhi ifakwe ngokucacile ukushintsha i-MP3.

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

Yebo — susa 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-AAC izogcina isilinganiso esifanayo sesampula njenge-WMA?

Ngephutha yebo — 48 kHz WMA ihlala 48 kHz ku AAC. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukushaya i-CD), isinqumo sesampula-sayizi sifaka ukusatshalaliswa okusezingeni eliphezulu kuleyo ngxenye yokungenisa ikhodi.

Ingabe ngizolungisa umsindo uma ngiguqula WMA ku AAC?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AAC, lubeka inhloso -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma kuhlanganiswa amabhayisikobho aqeqeshiwe ezingeni ezahlukene.

Ingabe AAC yami izodlala ku-car stereo, iPod, ne-Sonos?

MP3 idlala kuwo wonke amadivayisi. I-AAC idlala ku-Apple, ku-Android, ne-Sonos. I-FLAC idlala ku-Sonos ne-Android kodwa ayikho ku-iPods edlule. I-WAV idlala kuwo wonke amadivayisi kodwa inamandla amakhulu. Imenyu yokudonsa yedivayisi ethuthukisiwe ikhetha i-AAC codec elungele i-hardware yakho efanele.
