Yep, I've had a play with those -- it's awesome to think that JS is now 
fast enough to decode audio in realtime, but as you've discovered, it's 
not quite practical yet. On my PC, decoding MP3 in Firefox works well 
enough as long as you keep that window/tab in the foreground, but it 
starts skipping once you switch to another tab; my guess is that Firefox 
has some JS performance throttling that kicks in to prevent background 
tabs from using all of your CPU cycles.

Thanks
