Voice Record/Playback now possible?

Is it now possible to record a voice and play it back now? I thought I stumbled onto the idea a while back but was still a work in progress.

I believe you can. What you would do is store the samples into an array. I was trying to do this for to build a tone frequency recognizer. Once you have your sample in the array there should be a way to push the data back into the audio system.

So this is I believe you can.

What plugin or how is it done? Via User Media or some other plugin needed?

I'd also love to hear about a solution. Ideally I would even want to upload the recording to a server. Any tips would be apprecciated.
