Sound Manager 2
Working on this: SoundManager 2
(here’s a link to the base demo)
It seems really cool, especially if you can totally cusomize the look (which I will find out shortly).
Similar project, possibly using the same code
Open Tape
I did have a bit of trouble with Open Tape though, it wasn’t very flexible. I’m hoping sound manager will be better.
