Media Asset Management

I don't know if anybody who would be reading this would be able to help with this question, but I figured I'd ask anyway and see what the lazyweb can do for me...

Is anyone familiar with asset management systems geared towards audio files? It's easy to find vendors for systems that manage images and even video, but audio asset management systems seem a little harder to find. So, if you know of such a system, please leave a comment and let me know about it!
