AC3 kuya Opus Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-AC3 kuya ku-OPUS umguquli womsindo?

It re-encodes a AC3 audio file as OPUS. 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-OPUS output.

AC-3 yisandi esingenalutho esingena-channel, sivame u-5.1 ku-384 noma ku-448 kbps, ne-metadata yokuxoxa nokuhlanganiswa ngezansi. I-Opus iqala ngokukhuluma kusuka ku-6 kbps mono speech kuya ku-510 kbps stereo music ku-bitstream efanayo futhi ishintsha indlela ngokuzenzakalela.

Ingabe ngiyiphawula i OPUS ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo esemthethweni ngaphezulu kwe AC3, engeke ikwazi ukugcinwa kuphi naphi.

Lokhu kusho futhi ukuthi ubukhulu abukwazi ukuxazulula okungaphakathi: amabhokisi amaningi anjalo avunyelwe ukuphatha okungaphezu kwehlobo elinye lomsindo, ngakho amafayela amabili OPUS angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle.

Ingabe i-OPUS izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. AC3 i-decoded yinoma yini, kufaka phakathi iyunithi yemoto kanye nabadlali abadala; OPUS idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku AC3.

I-codec ifakwe iziqukathi zepatenti, futhi ilayisense ibekwe ngumuntu othumela umbhalo oguquliwe — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ifayela lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware, futhi kungani izinketho ezingenazo i-royalty zikhiwa.
