Your sound file representation looks and feels like just the top half of the sound file. I always feel I need to scroll down to see the bottom half of the file. The look and feel is just off for me. I suggest to have each file spike to the top and the bottom with the 0 point in the middle (like normal sound files.) It might not be a big deal to you, just that it makes me feel uncomfortable with sound in Camtasia because of this silly thing. I like the flat design of ver. 9. Good job.
