JSON

I am creating a GWT client application which interacts with a server and I am getting all my response data from the server in JSON format.

Amongst others there are wave data on the server's database which I would like to retrieve and then playback on the client. I am able to get the wave data as an array of bytes in the JSON format.

My problem is, how do I playback the wave array data in a browser? Is it even possible or do I have to find another solution?

I've searched the web and found some GWT packages which are able to playback sound, but they are all playing back directly from an url.
