AMR kuya Opus Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AMR ube Opus ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AMR futhi umguquli ukhetha i-Opus codec ne-bitrate ukufana nomsuka. Ukungabi naphutha Opus (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho Opus (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi.

Yini i-bitrate ongayisebenzisa ihele elivela ku-Opus?

Iphutha ngu-192 kbps ku Opus olahlekelwayo; ukudluliswa-kwe- Opus 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 AMR kuya ku Opus kuzonciphisa ubunjani bomsindo wami?

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

Ingabe i-AMR kuya ku-Opus igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku AMR isitoreji futhi zibhalwe ku Opus isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi.

Ingabe ngingenza i-batch yokuguqula amahele angama-AMR abe Opus?

Yebo — susa isibaya se AMR 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-Opus izogcina isilinganiso esifanayo sesampula njenge-AMR?

Ngephutha yebo — 48 kHz AMR ihlala 48 kHz ku Opus. 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 AMR ku Opus?

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

Ingabe Opus 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-Opus codec elungele i-hardware yakho efanele.

Ingabe ihele lami AMR liyimfihlo ngesikhathi sokuguqulwa ku Opus?

Yebo — amafayela alayishwe phezulu AMR aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala emuva, ukugcina isikhathi eside, noma ukuhlanganisa okuqukethwe kwesandi. Ifasitela lokugcinwa okuphelele likhona ku /privacy/.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-AMR libe Opus?

I-codec efanayo iphinde i-mux: 10 kuya ku-30 imizuzwana. Yenza kabusha i-codec eyahlukileyo: 10 kuya ku-20% yesikhathi somthombo, ngakho-ke ihora AMR → Opus liphela ngemizuzu engu-6 kuya ku-12. Imisebenzi yeqembu ihamba ngokufanayo phakathi kwabasebenzayo ukuze kube nokukhawulela okuningi.

Kungani i-Opus izwakala kakhulu noma ihlala incane kunaleli cebo i-AMR?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule isinqumo sokujwayelekile. Uma ubona ushintsho lwezinga, umdlali wakho womsindo noma ithala lemithombo lizosebenzisa i-ReplayGain noma ukuguqulwa kwezinga ngalinye lomdlalo — hhayi nathi. Ungasebenzisi lokhu ukulalela ama-Opus ajwayelekile.

Ingabe ngiguqula AMR ukulayisha phezulu kusuka kuzinsizakalo zokusakaza ku Opus?

Uma i-AMR ilayishwe phansi ingakhuselwanga (akukho DRM), yebo. Ama-streams abhalwe nge-DRM (ama-Spotify, ama-Apple Music tracks) abhalwe nge-crypto ku-bit level futhi asikwazi ukuwaphatha. Ama-Bandcamp, ama-SoundCloud alayishwe phansi, ukurekhodwa komuntu siqu, nama-podcast amafayela aguqulwa ngokucophelela.

AMR

I-AMR (I-Adaptive Multi-Rate) ifomethi yokuminyanisa yomsindo elungiselelwe ukubhalwa kwekhodi yenkulumo. Ivamise ukusetshenziswa kumakhalekhukhwini ukuqoshwa kwezwi nokudlalwa komsindo.

Opus

I-Opus iyikhodekhi yomsindo evulekile, engenamali enikeza ukucindezelwa kwekhwalithi ephezulu kukho kokubili inkulumo nomsindo ovamile. Ilungele izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi i-voice over IP (VoIP) nokusakaza.
