Bitrate ni umubare w'ibit compressor byo mu majwi umufata akoresha ku isegonda rimwe ry'ijwi: Standard ikoresha 64 kbps, High 128 kbps, na Best 192 kbps. Ku ijwi ry'umuntu, High (igenga) rimaze kumvikana neza; Best ifasha cyane indirimbo n'amajwi yivanze, naho Standard igabanya kabiri ubunini bw'inyandiko igihe igihe kiruta isuku.
Uhitamo urwego muri Settings → Quality mbere yo gukanda Record. Nk'uko indi myirondoro hamwe naryo, rirafungwa igihe iyo mirongo iri gukorwa, bityo gufata ntibigira guhindura quality hagati.
Urwego eshatu kimwe ku kindi
Ingano iri hasi ni imibare y'ubwenge bworoshye: kilobits ku isegonda ÷ 8 = kilobytes ku isegonda, bikubye igihe. Amadosiye ya Opus nyayo agera hafi y'ayo mibare, rimwe na rimwe akagenda munsi gato mu bice bisanzwe biragenda utuje.
| Quality | Bitrate | Ku isegonda | Ku munota | Ku isaha | Bijyanye neza |
|---|---|---|---|---|---|
| Bisanzwe | 64 kbps | 8 kB | 0.48 MB | 28.8 MB | |
| Hejuru (isanzwe) | 128 kbps | 16 kB | 0,96 MB | 57,6 MB | |
| Ibyiza | 192 kbps | 24 kB | 1.44 MB | 86.4 MB |
Kuki 64 kbps ishobora kumvikana neza
Amajwi ubwayo arimo kodegisi ya Opus, codec yagenewe gutekereza mubitekerezo. Opus kuri 64 kbps ituma ijwi rivuga risobanutse kandi risanzwe; abumva benshi ntibazabitoragura murwego rwo hejuru kuri mudasobwa zigendanwa cyangwa gutwi. Aho Standard itangiye kwerekana ni muburyo burambuye bwijwi: reverb yicyumba, guhumeka, gitari inyuma, cymbals mumajwi ya tab.
MP3 ninkuru itandukanye. Imiterere ya MP3 irashaje kandi idakora neza, kuburyo kuri 64 kbps ikunda kumvikana kandi "swirly" gato kuri frequency nyinshi. Niba uteganya kohereza hanze MP3, Hejuru niho umutekano utangirira.
Aho bitrate ikoreshwa
Igenamiterere ryiza rigaragara ahantu habiri:
- Mugihe ufata amajwi. Gufata wabitswe mubitabo byawe ni Opus amajwi kuri bitrate yatoranijwe. Ibi bishyiraho igisenge kubintu byose wohereza hanze nyuma.
- Mugihe cyohereza hanze. Kutagira WebM byandukuwe nta re-kodegisi, kandi WAV ntabwo PCM idacometse, ntabwo rero biterwa na bitrate mugihe cyo kohereza hanze.
Ibi birema umutego muto. Andika kuri Standard, hindukira kuri Byiza, wohereze MP3 - hanyuma ubone dosiye ya 192 kbps itwaye 64 kbps ifite ibisobanuro birambuye. Ninshuro eshatu nini kandi ntabwo byumvikana neza. Kuzamura bitrate nyuma ntizigera igarura ibyo kodegisi ya mbere yagabanutse.
Inyuma ni nziza: Ibyiza byoherezwa hanze hamwe na Standard yatoranijwe itanga compact MP3 cyangwa OGG yo kugabana mugihe 192 kbps yumwimerere iguma mubitabo.
Bitrate isangiwe hagati yimiyoboro
Umubare nigiteranyo cya dosiye, ntabwo kumuyoboro. Stereo ifata 128 kbps igabanya iyo ngengo ibumoso n'iburyo; gufata Mono itanga kbps 128 zose kumuyoboro umwe. Kubwijwi rimwe, mono kuri High ikunda kumvikana byibura nziza nka stereo kuri High, kandi dosiye nubunini bumwe. Ibindi kuri ibyo muri mono cyangwa stereo yo gufata amajwi.
Bitrate ntabwo ihwanye nigipimo cyicyitegererezo
Ifatwa ryose rifatwa kuri 48 kHz utitaye kubwiza. Igipimo cyicyitegererezo kigena inshuro ndende amajwi ashobora kuba arimo; bitrate ihitamo umubare muribyo bisobanuro birokoka compression. Guhindura ubuziranenge ntabwo bihindura igipimo cyicyitegererezo. 48 kHz ibisobanuro bikubiyemo icyo gice.
Niki bitrate idashobora gukosora
Bitrate yo hejuru irinda ubudahemuka ikintu cyose kigera kuri kodegisi, harimo ibibazo. Niba icyumba cyumvikanye, mikoro ni metero imwe, cyangwa ibyinjira birimo gukata, Ibyiza byandika ibyo bibazo muburyo burambuye. Mubunararibonye bwanjye mikoro yegereye hamwe nijwi ryumvikana rya microse itezimbere amajwi arenze kure kwimuka uva hejuru.
- Byijimye cyane cyangwa birarenze urusaku: hindura urwego rwa mikoro (0–200 %, ubusanzwe 100 %).
- Ijwi ry'umuyaga cyangwa urusaku rwa keyboard: komereza kuri Guhagarika urusaku (biba bihari by default).
- Abanyumvirebumva ibyuma by'igikoresho mu gihe uri mu kiganiro: komereza kuri Gukuraho urusaku rwa Echo.
Inyunganizi ngufi y'ibyemezo
- Iby'amasaha menshi y'inyigisho cyangwa ibiganiro by'umuzingo uzajya ubisoma vuba: Bisanzwe.
- Ikintu cyose gifite ijwi ushobora gusangiza abandi, gushikiriza, cyangwa guhindura: Hejuru.
- Umuziki, igitekerezo cy'indirimbo, cyangwa amajwi ya tablature aho amajwi y'inyuma agomba kubahirizwa: Byiza Kurusha.
Ububiko ntabwo ari cyo kintu cyemeza cyane, kuko amajwi abikwa mu bubiko bw'urubuga rwa mudasobwa gusa aherereye ku buryo bw'ububiko bwa disiki iboneka. Ariko, niba ubika amajwi menshi y'igihe kirekire, imibare y'isaha ku isaha muri gahunda y'ubunini bwa dosiye irihuta cyane.
