Isho ukuthini i-64, 128, no-192 kbps

I-Bitrate iyindlela amanani amabhithi omsindo ocindezelwe owachithwa ngumqoshisi ngomzuzwana ngamunye womsindo: Okujwayelekile kusebenzisa i-64 kbps, OkuPhezulu i-128 kbps, kanti Okungcono kakhulu i-192 kbps. Ngeviki, OkuPhezulu (okuyindlela ejwayelekile) sekuvele kuzwakala kuhlanzekile; Okungcono kakhulu kuzosiza kakhulu umculo nomsindo ohlanganisiwe wethebula, kanti Okujwayelekile kunciphisa usayizi wefayela uma isikhathi sibaluleke kakhulu kunokuhlanzeka.

Ukhetha izinga ku-Izilungiselelo → Ikhwalithi ngaphambi kokucofa Qopha. Njengeminye imisebenzi yokumisa, ivaliwe ngenkathi ukuqopha kusebenza, ngakho-ke ukuthatha okuthile akusoze kushintshe ikhwalithi phakathi nokuqopha.

Lezi zinga ezintathu eceleni komunye nomunye

Usayizi ongezansi uwubalo oluqondile: amakilobithi ngomzuzwana ÷ 8 = amakilobayithi ngomzuzwana, uphindwe isikhathi sokuhlala. Amafayela wangempela e-Opus asondele kulawa manani, kwesinye isikhathi ngaphansi kancane ngezikhathi ezithule.

Kungani u-64 kbps usengazwakala umuhle

Ukurekhoda ngokwako kufakwe ikhodi nge-Opus, ikhodekhi eklanywe ngenkulumo engqondweni. I-Opus ku-64 kbps igcina izwi elikhulunyiwe licacile futhi lingokwemvelo; iningi labalaleli ngeke likukhethe endaweni ephakeme kuzipikha eziphathwayo eziphathwayo noma ama-earbud. Lapho i-Standard iqala khona ukubonakala isemininingwaneni ezungeze izwi: isabizwana segumbi, ukuphefumula, isiginci ngemuva, amasimbali engomeni yomsindo wethebhu.

MP3 yindaba ehlukile. Ifomethi ethi MP3 indala futhi ayisebenzi kahle kangako, ngakho-ke ku-64 kbps ivamise ukuzwakala ibuthuntu futhi "i-swirly" kancane kumafrikhwensi aphezulu. Uma uhlela ukuthumela MP3, Okuphezulu indawo yokuqala ephephile.

Lapho kusetshenziswa khona i-bitrate

Isilungiselelo Sekhwalithi sivela ezindaweni ezimbili:

1. Ngenkathi uqopha. Ukuthathwa okulondolozwe kulabhulali yakho kuwumsindo we-Opus nge-bitrate ekhethiwe. Lokhu kubeka umkhawulo kuyo yonke into oyithumelayo ngokuhamba kwesikhathi.
2. Lapho uthumela. MP3, OGG, futhi amafayela angu-WebM asikiwe abhalwa ngekhodi ngekhwalithi ekhethiwe ngesikhathi ucindezela okuthi Landa noma Yabelana. I-WebM engasikiwe ikopishwa ngaphandle kokufakwa kabusha ngekhodi, futhi WAV iyi-PCM engacindezelwanga, ngakho futhi akuxhomekile ku-bitrate ngesikhathi sokuthekelisa.

Lokhu kudala ugibe oluncane. Rekhoda Okujwayelekile, shintshela kokuthi Okuhle kakhulu, thekelisa MP3 — futhi uthola ifayela elingu-192 kbps elinemininingwane enenani elingu-64 kbps. Inkulu ngokuphindwe kathathu futhi ayizwakali kangcono. Ukuphakamisa i-bitrate kamuva akubuyiseli lokho okuwiswe yikhodi yokuqala.

Okuhlehlayo kuhle: Ukuthatha Okungcono Kakhulu kuthunyelwa Kukhethwe Okujwayelekile kunikeza MP3 noma OGG ukuhlanganisana ngenkathi eyokuqala engu-192 kbps ihlala kulabhulali.

I-Bitrate yabelwa phakathi kwamashaneli

Inombolo iyisamba sefayela, hhayi isiteshi ngasinye. Ukuthatha kwe-Stereo kokungu-128 kbps kuhlukanisa isabelomali kwesokunxele nakwesokudla; ukuthatha kwe-Mono kunikeza wonke ama-kbps angu-128 esiteshini esisodwa. Ngezwi elilodwa, i-mono at Phezulu ivamise ukuzwakala kahle njenge-stereo kokuthi Phezulu, futhi ifayela lilingana nosayizi. Okuningi kulokho ku-mono noma isitiriyo sokuqoshwa kwezwi.

I-Bitrate ayifani nezinga lesampula

Konke okuthathwayo kuthwetshulwa ngo-48 kHz ngokunganaki Ikhwalithi. Izinga lesampula linquma imvamisa ephezulu kakhulu ukurekhoda okungaqukatha; i-bitrate inquma ukuthi ingakanani yaleyo mininingwane esindayo ekucindezelweni. Ukushintsha Ikhwalithi akushintshi isilinganiso sesampula. Isichazi esingu-48 kHz sihlanganisa leyo ngxenye.

Yini i-bitrate engakwazi ukukulungisa

I-bitrate ephezulu igcina ngokwethembeka noma yini efika kusifaki khodi, okuhlanganisa nezinkinga. Uma igumbi linanela, imakrofoni ikude ngemitha, noma okokufaka kuyasikwa, Okuhle kakhulu kuqopha lezo zinkinga ngemininingwane eyengeziwe. Ngokuhlangenwe nakho kwami ​​imakrofoni eseduze kanye nevolumu yemakrofoni ezwakalayo kuthuthukisa ukuqoshwa kwezwi kakhulu kunokusuka kokuthi Okuphezulu kuye Okungcono Kakhulu.

• Kuthule kakhulu noma kumeme kakhulu: lungisa isilayidi somthamo we-mic (0–200 %, okuzenzakalelayo 100 %).
• Ukukhishwa komoya wefan noma umsindo wekhibhodi: gcina i-Noise suppression ivuliwe (ivuliwe ngokuzenzakalelayo).
• Izikhulumi ezikhipha umsindo ku-mic ngesikhathi sokushayela: gcina i-Echo cancellation ivuliwe.

Umhlahlandlela omfushane wokuthatha izinqumo

• Amahora ambalwa wokufunda noma umsindo womhlangano owuzohlola ngokushesha: Ejwayelekile.
• Noma yini enezwi ongase wabelane ngayo, uqophe, noma uhlele: Okuphezulu.
• Umculo, umqondo wengoma, noma umsindo wethebhu lapho umsindo uphumelela khona: Okuhle Kakhulu.

Ukugcina izinto akujwayele ukuba yisici esinqumayo, ngoba izirekhodi zihlala esigcinweni sebhrawuza sendawo esinqunywe kuphela isikhala sediski esitholakalayo. Nokho-ke, uma ugcina amavidiyo amaningi amade, amanani amahora ngamahora kuthebula losayizi wefayela ahlanganisa ngokushesha.
