Kuthetha ukuthini i-64, 128, kunye ne-192 kbps

Ibhetayithi ngumgca werhafu yomsindo ocinezelweyo osetyenziselwa umzuzwana ngamnye womsindo: Esiqhelekileyo sisebenzisa 64 kbps, Esiphezulu 128 kbps, kwaye EsiPhucukileyo 192 kbps. Kwivoko, Esiphezulu (okukhethiweyo) sele liva ngokucacileyo; EsiPhucukileyo ikakhulu lunceda umculo kunye nomsindo oxubeneyo wethebhu, kwaye Esiqhelekileyo sinciphisa ubungakanani befayile xa ixesha libaluleke ngaphezu kobuhle.

Ukukhetha inqanaba kwenzeka ku-Useto → Umgangatho ngaphambi kokucinezela Ukurekhoda. Njengezinye iisetingi, ivaliwe ngelixa ukurekhoda kusebenza, ngoko ke ukuthatha akuzange kutshintshwe umgangatho phakathi.

Amanqanaba amathathu ecaleni komnye

Ubungakanani obusezantsi bungama-arithmetiki aqhelekileyo: iikilibhithi ngomzuzwana ÷ 8 = iikilobyithi ngomzuzwana, ziphindwe ixesha. Iifayile zeOpus zangempela zisondele kule manani, ngamanye amaxesha kancinci ngaphantsi ngexesha leencwadi zomnxeba.

Kutheni i-64 kbps isenokuvakala ilungile

Ushicilelo ngokwalo lufakwe ngekhowudi nge-Opus, icodec eyilwe ngentetho engqondweni. I-Opus ku-64 kbps igcina ilizwi elithethiweyo licacile kwaye lendalo; uninzi lwabaphulaphuli aluyi kuyikhetha kwindawo ephezulu kwizithethi zelaptop okanye ii-earbuds. Apho uMgangatho uqala khona ukubonakalisa kukwiinkcukacha ezingqonge ilizwi: isenzi segumbi, ukuphefumla, isiginkci ngasemva, amacangci akwingoma yethebhu.

MP3 libali elahlukileyo. I-MP3 ifomathi indala kwaye ayisebenzi kakuhle, ngoko ke kwi-64 kbps ithande ukuvakala isandi kwaye kancinane "i-swirly" kwiifrikhwensi eziphezulu. Ukuba uceba ukuthumela ngaphandle MP3, Phezulu yindawo ekhuselekileyo yokuqalisa.

Apho ibitrate isetyenziswa khona

Useto loMgangatho luvela kwiindawo ezimbini:

1. Ngelixa urekhoda. Uthatho olugcinwe kwithala lakho yi-Opus yomsindo ngebitrate ekhethiweyo. Oku kumisela isilingi kuyo yonke into oyithumela ngaphandle kamva.
2. Xa uthumela ngaphandle. MP3, OGG, kwaye zilungiswe WebM iifayile zifakwe ngekhowudi kuMgangatho okhethiweyo ngeli xesha ucinezela u-Khuphela okanye Yabelana. I-Untrimmed WebM ikhutshelwe ngaphandle kwe-encoding kwakhona, kwaye WAV ayicinezelekanga iPCM, ngoko ke ayixhomekekanga kwibitrate ngexesha lokuthumela ngaphandle.

Oku kudala umgibe omncinci. Rekhoda kumgangatho, tshintshela kweYona, thumela ngaphandle MP3 - kwaye ufumana ifayile ye-192 kbps ephethe i-64 kbps enexabiso leenkcukacha. Inkulu ngokuphindwe kathathu kwaye ayivakali ngcono. Ukunyusa ibitrate kamva akunakubuyisela into eyehliweyo yikhowudi yokuqala.

Umva ulungile: Eyona nto ingcono ithunyelwe ngaphandle ngoMgangatho okhethiweyo unika ubumbano MP3 okanye OGG yokwabelana ngelixa i-192 kbps yoqobo ihlala kwithala leencwadi.

I-Bitrate yabelwana phakathi kwamajelo

Inani lilonke lefayile, hayi ngetshaneli nganye. I-Stereo ithatha kwi-128 kbps yokwahlula uhlahlo lwabiwo-mali ngapha nangapha ekhohlo nasekunene; a Mono ukuthatha unika iyonke 128 kbps kwisitishi esinye. Ngelizwi elinye, i-mono ePhakamileyo ithande ukuvakala ilungile njenge-stereo Phezulu, kwaye ifayile ilingana nobukhulu. Ngakumbi ngaloo nto kwi-mono okanye istiriyo ukwenzela ushicilelo lwelizwi.

I-Bitrate ayifani nomlinganiselo wesampuli

Yonke into ethathiweyo ibanjwa nge-48 kHz kungajongwanga uMgangatho. Ireyithi yesampulu ithatha isigqibo ngeyona ndawo iphezulu yokurekhodwa enokuqulatha; I-bitrate ithatha isigqibo sokuba ingakanani na loo nkcukacha isindayo kuxinzelelo. Ukutshintsha uMgangatho akutshintshi ireyithi yesampulu. Isichazi se-48 kHz sigubungela eso siqingatha.

Yeyiphi ibitrate engakwaziyo ukuyilungisa

I-bitrate ephezulu ngokuthembeka igcina nantoni na efikelela kwi-encoder, kuquka iingxaki. Ukuba igumbi liyavakala, i-microphone ikude nemitha, okanye igalelo liyanqunyulwa, Eyona nto ingcono irekhoda ezo ngxaki ngokweenkcukacha ngakumbi. Kumava am i-microphone esondeleyo kunye nomthamo we-mic onengqondo uphucula ukurekhoda kwezwi ngaphezu kokusuka kwi-High to Best.

• Ityala elithule kakhulu okanye live kakhulu: lungisa isilayida sovolumu yemakrofoni (0–200 %, ezikhethiweyo 100 %).
• Umsindo wefan okanye wekhibhodi: gcina uMthetho wokunciphisa uMoya ungasebenzi (ukuba uvuliwe ngohlobo olungagqibekanga).
• Izithethi zityhumkela kumakrofoni kwifowuni: gcina uMva wokucima umsindo uvuliwe.

Isikhokelo esifutshane sokuthatha isigqibo

• Iiyure ezininzi zomfundiso okanye umsindo womhlangano oza kuwuhamba ngokukhawuleza: Ezilungileyo.
• Naluphi na ulwimi onokulwabelana ngalo, nokukhetha, okanye ukuhlela: Phezulu.
• Umculo, umbono wengoma, okanye umsindo wethebhu apho ingoma ibalulekile: Eyona ilungileyo.

Ukugcinwa kwefayile akuhlali kuyinto ephambili ekuthatheni isigqibo, kuba iirekhodi zihlala kwindawo yokugcina yesikhangeli esikhawulelwe kuphela yindawo ekhoyo yokugcina. Nangona kunjalo, ukuba ugcina iinkcukacha ezininzi ezide, amanani eehora-nga-iyure kwitafile yobungakanani befayile aya qokelela ngokukhawuleza.
