AMR ukuba Opus Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AMR yesandi ibe yi-Opus ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili AMR kwaye umguquli wethu ukhetha Opus i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (Opus = WAV / FLAC / ALAC) sigcina yonke isampuli; isiphelo esilahliweyo (Opus = MP3 / AAC / OGG) simiselwe kwi-192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-Opus ifayili isebenzisa i-bitrate enjani?

Okwendalo 192 kbps ye-lossy Opus; idlula-kwi-lossless Opus. Nciphisa kwi-320 kbps ye-audiophile okanye kwi-96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwi-bitrates ephantsi kakhulu.

Ingaba ukutshintsha ukusuka ku AMR ukuya ku Opus kuya kunyusa ubunjani besandi sam?

Ukuba AMR ilahlekile kwaye Opus ayilahleki (umzekelo MP3 → WAV), ifayili Opus ayingcono kune AMR — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba AMR ayilahleki kwaye Opus ilahlekile, lindele ukuba i-Opus codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

Ingaba i-AMR ukuya kwi-Opus igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, imifanekiso ye-albham ifundwa kwi AMR kwaye ibhalwe kwi Opus isiqulathi seefayili (lapho i-Opus ixhasa i-tags, eyenza zonke eziqhelekileyo).

Ndingaguqula izigidi zeefayili AMR zibe Opus?

Ewe - susa isiqulathi seefayili se AMR ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ingaba i-Opus iya kugcina inqanaba lesampuli elifanayo njenge-AMR?

Ngokungagqibekanga ewe (48 kHz AMR → 48 kHz Opus). Ukuba ufuna ukunyusa isampulu ukuhambelana (umzekelo. 96 kHz → 44.1 kHz yokushicilela i-CD) ukhetho lwesampulu-yexabiso eliphambili yenza oku ngesampulu ephezulu yomgangatho.

Ndingazilungisa njani ilizwi kwinyathelo AMR ukuya kwi Opus?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye Opus, ibeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo.

Ingaba i-Opus iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos?

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, incinci kakhulu kwi-iPods edala. I-WAV idlala kuyo yonke into kodwa ikhulu. Iinketho eziphambili ziquka isixhobo esimiselweyo kwezi zinjongo eziqhelekileyo.

Ingaba ifayili yam AMR ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AMR ziqhubekekiswa kubasebenzi abamiselweyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise okuqulethwe sisiqulatho sesandi.

Ithatha ixesha elingakanani ukutshintsha i-AMR yeyure enye ibe yi-Opus?

I-codec efanayo ye-re-mux: 10-30 imizuzwana. Yenza kwakhona ikhowudi kwi-codec eyahlukileyo: ngokuqhelekileyo 10-20% yobude bomthombo, ngoko ke i-1-iyure AMR → Opus igqiba kwimizuzu eyi-6-12.

Kutheni i-Opus ifayili inamandla / ipholile kune-AMR imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uvule ukhetho lokumisela ngokuqhelekileyo. Ukuba ubona utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya inokuba isebenzisa ukuphinda udlala ukufumana kwakhona okanye ukulungisa i-track nganye kukudlala — hayi nathi.

Ukuba i-AMR ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo nge-DRM (i-Spotify, i-Apple Music) zifihliweyo kwinqanaba le-bit kwaye asikwazi ukuziqhubekekisa. Amacebo e-Bandcamp, ukulayisha i-SoundCloud, kunye nokulinganisa kobuqu buguqulwa kakuhle.

AMR

I-AMR yi-codec yokuthetha elungele ukurekhodwa kwelizwi kunye noqhagamshelwano lwefowuni, oko kukuthi, iingoma zengoma zidla ngokubi kuyo.

Opus

Opus yi-codec yesandi evulekileyo eyaziwayo ebetha i-MP3 ne-AAC kwi-bitrates ephantsi, ngenxa yoko unxibelelwano lwelizwi kunye nokudlulisa kusetyenziswa.
