Google tau tshaj tawm qhov kev tso tawm ntawm Lyra 1.3 audio codec, tsom mus rau kev ua tiav lub suab zoo hauv cov xwm txheej ntawm cov ntaub ntawv xa mus tsawg. Kev hais lus zoo ntawm bitrates ntawm 3.2 kbps, 6 kbps thiab 9.2 kbps thaum siv lub Lyra codec yog kwv yees li sib npaug rau bitrates ntawm 10 kbps, 13 kbps thiab 14 kbps thaum siv Opus codec. Txhawm rau daws qhov teeb meem no, ntxiv rau cov txheej txheem ntawm lub suab compression thiab teeb liab hloov dua siab tshiab, Lyra siv cov qauv hais lus raws li kev kawm tshuab, uas tso cai rau koj rov tsim cov ntaub ntawv ploj lawm raws li cov yam ntxwv hais lus. Kev siv cov cai siv yog sau hauv C ++ thiab muab faib raws li Apache 2.0 daim ntawv tso cai.
Tsis zoo li qhov radically redesigned tso tawm ntawm Lyra 1.2 npaj rau lub Kaum Hli Ntuj, txhais mus rau ib tug tshiab neural network architecture, version 1.3 optimizes lub tshuab kawm qauv yam tsis muaj kev hloov architectural. Tus tshiab version siv 32-ntsis integers es tsis txhob ntawm 8-ntsis ntab taw tes tus lej los khaws qhov hnyav thiab ua haujlwm lej, ua rau 43% txo qis hauv cov qauv loj thiab 20% nrawm thaum kuaj ntawm Pixel 6 Pro smartphone. Kev hais lus zoo tau khaws cia nyob rau tib theem, tab sis cov qauv ntawm cov ntaub ntawv xa tawm tau hloov pauv thiab tsis sib xws nrog kev tshaj tawm yav dhau los.
