I-FLAC isebenzisa umbono othe tyaba kunye nokukhowuda kweRice ukufezekisa malunga ne-50-60% yobungakanani obuqhelekileyo ngelixa ikhupha ikhowudi kwakhona kwi-PCM efana ne-bit. Opus ilinganisela ukusuka kwi 6 kbps mono ukuthetha ukuya kwi 510 kbps stereo iingoma kwi bitstream efanayo kwaye itshintshe iimo ngokuzenzekelayo.

Ingaba ndilahlekelwe yintoni ngokuguqula i FLAC ibe yi Opus?
