Google har publicerat version 1.3 av ljudkodeken Lyra, som fokuserar p\u00e5 att uppn\u00e5 h\u00f6g kvalitet p\u00e5 r\u00f6st\u00f6verf\u00f6ring under f\u00f6rh\u00e5llanden med begr\u00e4nsad \u00f6verf\u00f6ringskapacitet. R\u00f6stkvaliteten vid bitrate 3,2 kbps, 6 kbps och 9,2 kbps med kodeken Lyra motsvarar ungef\u00e4r bitraten 10 kbps, 13 kbps och 14 kbps med kodeken Opus. F\u00f6r att l\u00f6sa uppgiften anv\u00e4nder Lyra inte bara vanliga ljudkompressionsmetoder och signalsystem, utan \u00e4ven en talmodell baserad p\u00e5 maskininl\u00e4rning som g\u00f6r det m\u00f6jligt att \u00e5terskapa saknad information baserat p\u00e5 typiska talegenskaper. Referensimplementationen av koden \u00e4r skriven i C++ och distribueras under Apache 2.0-licensen. <\/p>\n

I j\u00e4mf\u00f6relse med den radikalt omarbetade versionen 1.2 av Lyra, som lanserades i oktober och flyttades till en ny neurala n\u00e4tverksarkitektur, har version 1.3 genomg\u00e5tt en optimering av maskininl\u00e4rningsmodellen utan arkitektoniska f\u00f6r\u00e4ndringar. I den nya versionen anv\u00e4nds 8-bitars heltal f\u00f6r lagring av vikter och utf\u00f6rande av aritmetiska operationer ist\u00e4llet f\u00f6r 32-bitars flyttal, vilket har lett till en minskning av modellens storlek med 43% och en hastighets\u00f6kning p\u00e5 20% vid test p\u00e5 smartphones, som Pixel 6 Pro. R\u00f6stkvaliteten har kunnat bibeh\u00e5llas p\u00e5 samma niv\u00e5, men formatet p\u00e5 de \u00f6verf\u00f6rda data har \u00e4ndrats och \u00e4r inte kompatibelt med tidigare versioner.
