  1. This is a newbie question. I just downloaded and installed wave pad (free version). I cannot figure out how to do the following: I take a plain golf club shaft (that does not have a clubhead) and clamp one end in a vise. I then set up a piece of wood (and a microphone) near the other end of the shaft and I attach a small plastic strip upright to the wood, so that when I "pluck" the free end of the shaft, the shaft will vibrate back and forth. As the shaft vibrates, it will click the plastic strip and thus, I wll record the clicking sound into Wave pad. The sound would be like when kids put baseball cards in the spokes of their bikes. What I want to do with the recorded sound is detemine the average number of clicks per second (or per 5 seconds, etc.). The overall purpose is to be able to determine if two golf shafts have the same frequency when plucked. The only way I can figure out now how to do this is to record the sample; then trim off the ends (to get rid of dead time) and then to physically count the number of clicks on the wave chart and divide by the file time length. So, for example, if I had 22 clicks in a 4.15 second sample, that would give me a frequency of about 5.3 clicks per second. Does this seem right? Is there a way the wave pad program will automatically do that frequency computation? Thanks, Bob
