Is there a web-based audio editor?

Factual Questions
1

I’m wondering if there is a browser-based sound editor that will modify WAV files I have on a server.

I know about Audacity, and sox, but I’m looking for some components I can put on a web site so that a user can amplify audio files stored on the server, and perhaps even trim out unwanted parts.

Does anything like that exist?

Thanks.

[del]IIRC there are a few. myna is the first example I could find.[/del] Never mind. I don’t know any freely distributable online audio editor. There probably are some, though.
