Kwi bitrate elungileyo engaziwayo kuninzi lwaba bonke. Into engayiyo ibuyiselwa, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele eyakuqala. Opus ilinganisela ukusuka kwi 6 kbps mono ukuthetha ukuya kwi 510 kbps stereo iingoma kwi bitstream efanayo kwaye itshintshe iimo ngokuzenzekelayo.

Kutheni i-web inikezelwa njenge Opus?
