Remember that funky DRA audio format we mentioned way back in July of last year? Yeah, somehow that just got approved by the BDA. While we're sure the likes of DTS and Dolby won't be up all night fearing for tomorrow, there actually is another audio format in the Blu-ray town. Over in Beijing, the Blu-ray Disc Association, China Hualu Group and Digital Rise Technology have gathered together to announce that the DRA digital audio coding technology has been approved for inclusion in the BD-ROM 2.3 specification as an "optional audio codec." The folks involved seem pretty stoked, but seriously, what are the chances any mainstream Blu-ray Disc ships this year (or ever, really) with a DRA soundtrack? Anyone placing bets?
