Wojtek,

Thanks for making this available.

I had an audio record project last year that didn't turn out as well as 
hoped because audio quality was not very good. I hope I can find some hints 
in your code that will help me.

In my opinion, your documentation is better than you said.

Thank you again,
Richard
