Opus is an open audio codec designed for interactive speech and music transmission.
Ho sa tsotelehe hore na encoder ea mantlha e entse qeto ea ho e tlosa,'me ha e ka khutlisoa. Opus e kopanya ka ho etsa hore eng eo hlooho e ke keng ea e bona - li-sounds tse sireletsehileng li lula ka tlase ho tse matla, li-frequencies ka lehlakoreng la ho utloa - le ho e tlosa ka ho sa feleng. Ka bitrate e phetseng hantle e sa utloahaleng ho batho ba bangata. Seo e seng sona se ka khutlisoa, ka hona ho fetola ho formate e sa hlokeng ho boloka boemo ba hona joale ho feta ho khutlisa sehlooho se kaholimo. Li-microchips tse nang le li-chips tse 1000 li ka sebelisoa ho etsa li-chips tse 5000, tse nang le li-chips tse 10 le tse 10 ka bobeli.
Ka lebaka la horentsoe ka ho khetheha bakeng sa mosebetsi oo: li-file tse nyane, ho qala ka potlako, ha ho na plugin le laesense ea ho tšoenyeha ka eona. E etsa hore e be e ntle ho fana ka leseli le sa tloaelehang ka tsohle tse ling - lisebelisoa tsa ho hlophisa, li-gallery tsa thekeng le lisebelisoa tse fetileng li e tlohela kamehla. Ho fetola ho ea ho mofuta oa sepheo sa mantlha ke seo se etsang hore litaba tse bolokiloeng li sebelisetsoe ho tsoa webosaeteng. Opus ke codec e ntle ka ho fetisisa e nang le li-bitrates tse tlase ka mahlakoreng a hlakileng,'me e fana ka li-notes tsa molumo tsa WhatsApp, Discord le WebRTC.
Ee — mofuta ona o sebetsana ka ho nepahetseng le li-channel tse fetang tse peli, ka hona ho kopanya li-surround ho boloka ho hlophisoa ha li-channel ho feta ho e-ba le ho koaloa ho stereo ka tsela e ka hare. Haeba u e utloa e le li-surround e itšetlehile ka ho qetela: mofuputsi o tla decode li-channel tsohle, mohala o tla koaloa ka nako ea ho bapala ntle le ho tšoenyeha. Ho fetola ho mofuta oa stereo feela ho etsa hore ho koaloa ho be le nako e telele.
Ho feta joalo selemo le selemo, empa phapang ke ea 'nete. Software tšehetso e fihla ka potlako; hardware tšehetso feela e tla le lisebelisoa tse ncha, le fono, TV kapa player ka pele ho uena ka ho le bonolo ho tla ba pele ho eona. Ha e tšehetsoa e ka ba molemo ho feta ka ho lekana ho feta formate fetola, ke ka hona e lokela ho fetoloa ho ea ho fana le ho fetoloa ho tsoa ho ea ho lumellana.
Ha ho joalo. Opus ke e 'ngoe ea li-formats tsa audio tse nang le li-browser tse nang le li-decode, ka hona e ka ba le li-element tsa audio kapa podcast player mme e sebetsa ka hohle ntle le plugin kapa faele ea fallback. E etsa hore e be le sepheo sa ho phatlalatsa se sireletsehileng, mme ke ka hona ho fetola ho ngolisoa ha sepheo ho ea ho mofuta ona ka linako tse ling ke tsela e khuts'oane ea ho e fumana ho bapala sebakeng sa marang-rang.
Ho lumellana le sebaka sa ho qetela, eseng le sehlooho. Bakeng sa lipina, 256 ho 320 kbps e hlakile ho ba balateli ba bangata; bakeng sa puo le podcasts, 96 ho 128 kbps e ngata ebile e tlisa faele ka ho le letšehali. Ho kopitsa ka holimo ho bitrate ea sehlooho ke sebaka se senyehileng — e boloka molumo o neng o se o ntse o na le ho tsoa ha ho na ho lahleheloa ke nako mme ha e khutlisetse eng kapa eng eo encoder ea pele e neng e e tlohetse.
Ha ho motho, ka tsela eo e leng bohlokoa: ho hlalosa ke sechaba, ho phethela ke mahala ho ngola, le ho se na k'hamphani e ka fetola maemo a morao tjena. Ke ka hona e hlahang ka lisebelisoa tsa open-source le ka melao ea ho boloka, moo mofuta o hlophisitsoeng ke morekisi e mong o le kotsi. The trade ke tšehetso ea khoebo - e ka ba nako e telele ea mofuta le ho hlalosa e ntle ka ho fetisisa le ho lumellana ha sesebelisoa sa patchiest. Opus ke setsi sa IETF se thehiloeng ka 2012 se kopantseng Skype's SILK speech codec le Xiph's CELT music codec ho etsa moralo o le mong.
Ha ho joalo ho sa tsotellehe hore na u e botsa. Ho fetoloa ho boloka palo ea mohloli — 48 kHz e lula e le 48 kHz, 44.1 kHz e lula e le 44.1 kHz — hobane ho khutlisa lipalo ke theko e nyane ea boleng bakeng sa melemo e seng teng ha ho na ntho e e hlokang. Li-exceptions ke tsa 'nete: CD tsa molumo li hloka 44.1 kHz, ba bang ba bapalami ba hardware ba khale ba amohelang ntho e ngoe le e ngoe, le li-pipelines tsa puo li batla 16 kHz. Sebetsa palo ka ho hlakileng ka linako tsena'me u e siee e le eona feela haeba ho le joalo.
Ha ho mohla,'me ho bohlokoa ho utloisisa hobaneng: ho eketseha ke letšoao, ha bytes ka hare e hlophisitsoe bakeng sa mofuta o itseng. Ho fetola lebitso ho hlahisa faele eo lebitso la eona le etsang hore ho be le ntho e itseng eo ho nang le eona ha e fane ka eona, le seo e se etsang ho bula e ka nka faele kapa e e bala ka tsela e mpe. Ho khetheha ho le mong ho na le li-formats tse peli tse nang le li-container tse tšoanang ka lebitso le fapaneng - le ka nako eo ho khutlisa ka ho nepahetseng ho sireletsehile ho feta ho fetola lebitso.
E hlakoloa ka ho toba. Ho kenya le phello e fetotsoeng e lula ho li-server tsa rona ka lihora tse ka bang 24, e leng e le nako ea ho kenya phello,'me e tlosoa ka ho hloekisa ka ho toba.
