Hi Charles, I'm not knowledgeable about electronics at all. I read your white paper on Minimum Phase and thought I had a basic understanding of what your Minimum Phase filters were doing. Here is a quote from the white paper describing the effect of an apodizing filter,
"Furthermore all pre-ringing from the recording process has been
filtered out, and the new playback filter only has post-ringing."My understanding of the white paper is that your MP filter builds on the apodizing filter's removal of the pre-ringing by minimizinging the post-ringing.
Then I read the following in your post below, "It is this apodizing filter that is *supposed* to filter out problems created by the ADC. But I can't say that the thing really works. It doesn't sound bad, in fact it sounds pretty good. But it doesn't sound as good to me as our "Listen" filter that *doesn't* filter out the alleged ringing that the ADC puts on the disc."
So I'm confused, can you briefly explain what your Listen filter is removing? Thanks, Tom
