For a variety of reasons, I think I'll be switching to MP3. I have already encoded the 'recent' talks in MP3, and I think I'll go back and re-encode the first months talks too.

Now I didn't try the apps you mention. I wasn't happy with the results, when I used lower rates, using the tools I had available at the time. I will be continuing to experiment with the sizes, rates and qualities as time goes on.

Thanks for your example. I will check it out.
