Mac Users: Where can I find a free voice recorder online?

I downloaded a soundwav recorder called Recordpad, but it doesn't allow me to edit how big the file is. It's pretty much a plain jane recorder. I'm not looking for anything fancy but just something where perhaps the .wavs won't turn out as a huge file to the point where it will take a long time to download. Anyone know where I can download a free decent sound .wav recorder?
