Question about using a GPL library in a commercial project

Hi,

I want to use this online recorder in my website:

Can I use this code in a commercial project? I know that the as3wavsound library is under MIT license that allows this. What about Kikko-shine GPL library ? Can I use the library in my commercial project? it is not a software product, it is an audio website that allows the users to record online and have audio channels with subscriptions.

Thanks in advance.
