Opus kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-OPUS kuya ku-AMR umguquli womsindo?

It re-encodes a OPUS audio file as AMR. Sample rate and channel count are preserved; the difference is the codec and container.

Ingabe isilinganiso sesampula kanye nesimo sesixhumi sigcinwa?

Ngephutha yebo — i-stereo ihlala i-stereo, isilinganiso sesampula sakuqala (44.1 kHz, 48 kHz, njll.) sithunyelwe ku-AMR output.

Ingabe OPUS kuya ku AMR ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-AMR emuva ku-OPUS kule site. Uma ifomethi eyodwa ilahlekile, i-round-trip ayilungile noma ngabe ibukeka noma izwakala ifana.

Yini ikhwalithi yesipiliyoni okufanele ngilinde kusuka ku-OPUS kuya ku-AMR?

Izilungiselelo ezizenzakalelayo zidinga ukusakazwa / ukhwalithi ye-web — ngokubona kufana nomthombo weningi labasebenzisi. Ukusetshenziswa kwegobolondo, khetha ukhetho lwekhwalithi ephezulu kuzinhlelo zokushintsha.

Ingabe ukushintsha OPUS kuya ku AMR kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i AMR encoder isebenza kusuka kumsindo osele udlulele esinye isikhala se-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une master engalahlekelwa yilutho, ukukopisha i AMR kusuka lapho kunciphisa isikhala esimibili ngokuphelele. I-Opus iqala ngokukhuluma kusuka ku-6 kbps mono speech kuya ku-510 kbps stereo music ku-bitstream efanayo futhi ishintsha indlela ngokuzenzakalela. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum.

Ingabe izihloko zesikhashana sami kanye nesithombe se-albhamu sizohlala isikhathi eside uma siguqulwa OPUS kuya ku AMR?

Akunalutho. OPUS ifaka i-metadata efanele, kodwa AMR ayinaso isikhala esijwayelekile somuntu oculi, i-albhamu, inani le-track noma umhlobiso we-cover, ngakho-ke amathegi asuswa ngaphandle kokulahleka. Gcina i-OPUS njengekhophi elabelwe, noma uphinde ubeke i-tag ngemuva ngethuluzi njenge Mp3tag noma MusicBrainz Picard. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Yini okushoyo ihele AMR?

Ukuhamba okuncane kwefremu yomsindo okhonjiswanga ngaphandle kwebhokisi elijikelezayo. Lokhu kusho ukuthi amafayela amabili AMR angaxhunywa ngokulula ngokubeka elinye ngemuva kwelinye, futhi ngokufanayo kusho ukuthi konke okungaphezu komsindo - ubude, ukufuna isibalo, ukuhoxa umdwebo - kufanele kufakwe ibhodlela njengenhlanganiso ngaphezu kokuyingxenye yefomethi, ngakho umdlali kufanele afunde ihele lonke ukuze asebenze ukuthi lide kangakanani. Kulokhu, into elula kakhulu ebizwa ngokuthi ihele lomsindo, okuwukuthi kungani livela ngaphakathi kwezinye izibhokisi ngaphezu kokuvela ngokwalo.

Yini ekwenzeke kumsindo othile uma uguqula OPUS ku AMR?

Ihlolwe phansi ku-stereo, ngoba AMR ayinayo indlela esebenzayo ye-multichannel. Ukuhlanganisa phansi kusetshenziswa izilinganiso ezijwayelekile ukuze umhlangano we-channel ephakathi uhlale ucacile futhi izingqimba zixhunywe ku-level ephansi. Noma yini esekelwe ekubekeni kwe-channel ehlukile idlule uma lokhu kwenzeke.

Ingabe amafayela OPUS avame ukuvelaphi?

Kusuka kwi-web, futhi ngaphezu kwesoftware kune-hardware. OPUS yakhiwa ukusakazwa nokukhishwa kwe-open-source tool chains, ngakho ivela kuma-game assets, ukurekhodwa kwe-browser, ama-podcast pipelines kanye nanoma yini eyenziwe ngabantu abangafunanga ukuxhumana kwelayisense. Okungabonakala kuyizimpahla ze-electronic, okuyisizathu esijwayelekile sokuthi umuntu kufanele aguqule enye yonke. Opus kuyinto IETF standard kusukela 2012 ukuthi wahlanganisa Skype SILK ulwimi codec ne Xiph CELT music codec eyenziwe eyodwa.

Ingabe OPUS imahhala ukuyisebenzisa nokusakaza?

Yebo, ngaphandle kwezimo ezifanele ukukhathazeka ngazo. Ulwazi olucacisiwe luyiqiniso, wonke umuntu angafaka umbhalo-mbhalo noma umbhalo-mbhalo oguquliwe ngaphandle kokubuza noma ukukhokha, futhi akukho muntu ongashintsha la mazwi ngemuva - ngakho-ke kuvela ku-open-source tooling, kuma-engine wemidlalo nakwezinye izindawo lapho i-license negotiation ibulala iphrojekthi. Ukushintshana isuka kuyo akuyibuyisela emuva lokho; amafayela akhona ahlala ngokugcwele njenge-useable njengoba bekhona.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-OPUS ibe yi-AMR?

Ukuthunyelwa okungaziwa kuvunyelwe ngokuzenzakalela; ama-akhawunti abhalisiwe amahhala athola umkhawulo ophezulu, futhi ama-akhawunti we-Pro angeke abe ne-limit yefayela ngalinye. Umlando wesiphequluli uvame ukuba ngumkhawulo osebenzayo ngaphambi kokuba umkhawulo wethu we-server-side uqale.

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-OPUS elilodwa libe yi-AMR?

Yebo. Thola noma khetha amafayela amaningi we-OPUS ku-upload eyodwa — umguquli usebenza ngazo ngokufanayo futhi ubuyisela i-ZIP yemiphumela ye-AMR. Akunasidingo sokuphinda isikhashana sokufaka ihele ngalinye.
