It’s prety neat, you can preview mp3s in page, we’ve been using it at Headhug, a friends mp3 blog for a while now. Best of all it’s really easy to get it up and running.
The first version used jQuery which caused a few problems, but it’s been re-written from scratch for the latest version. The main aims are to make it unobtrusive, easy to use and to play nicely with other JS libraries. So far, it’s pretty good.
The main version is available from the official 1Bit site, which has the downloads, documentation. Everything you need to use it on your own site or blog. There’s also the in-development version on my site where i’ve been playing around and trying to improve it, it also has some more demo’s.
So go check out 1 Bit, its nifty.
