Rockbox should have it fairly soon, and the decoder implementation is integer and reasonably efficient (much optimization is still needed however).

Any info on how well it performs? From what I heard about the Opus decoder for Windows (or generally x86/x64), it is much slower than decoders for other lossy formats. On a portable device battery usage is a really important issue for an audio format.

This is a bit of a repeat of what I posted in a thread about audiobooks, but more on topic here. At this point (still not considered a stable release) Opus decodes fine on my E200 sansa at 12 kb/s (speech). It's about at the edge but works at 64 kb/s, and hangs up the controls at 128 kb/s. I'm told there is still a lot of improvement possible. At this point I will switch to Opus for speech but for music I'll wait.

Haven't tried it on my android tablet, but the power usage analysis shows the vast majority of power going to the display pretty much whatever I run even with wifi and GPS running, and the display goes to sleep after a few minutes if I'm just playing audio. On that device I've been sticking with Google music as I can have everything on the cloud and specify albums to be cached locally (for when I'm out of wifi range) and all works well... except that program is basically centered around MP3. I may get another app that handles Opus just to try it, but I'm limited to 16 GB total local storage so I really like the cloud aspect of google music.
