Charles:
Your MP white paper has to be one of the best ever at explaining digital filtering so that just about anyone could understand it. The text was kept simple and the graphs clearly supported it. Two questions:
1. How come no one thought of this before? As stated in the text, part of your idea was based on Peter Craven’s AES paper that came out in 2004.
2. How do you think your competitors would respond to this? For example, do you think they would say this is an oversimplification?
Thank you.
Gerry
