My work with Overtone Analyzer continues to be a great pleasure. Comparing individual passages is now working very well, and by now I'm using this program exclusively to document and archive my patient records.
I just installed Overtone Analyzer and was pleased about the intuitive and pleasant user interface and the appealing graphic design.
Many thanks for your excellent work. My compliments for the new features. Working with your program is now even more fun than it already used to be.
Congratulations on the new version of Overtone Analyzer. It is excellent. Every university in the world should have one.

This is one product that should be worth its weight in gold, because it works so well and is easy to use as well.
