Can we record a visitor's voice Using Flash / ActionScript on a Website?

[nicebasic]

This question has been in my mind for a long time.

A few months ago, I saw a site about singers. People could go to the site and sing a song they liked. The site recorded their voice.

How do they do that? Do they use Flash/ActionScript?

What's the best way to do this?

The name of the site is SingSnap.com

Does anyone have a suggestion?

Thanks in advance.
