I am new to the art. I see many references to the projectile velocity. Are those estimates or measured, and if measured, how?
Nope, you can get one from Amazon for $80.22 with free shipping.Thanks so much! Now I know. Looks expensive though.
Thanks! I had audacity on a computer some years back. I will look into it if my skill improves sufficiently to warrant the effort. Cool video.the other option is to make one yourself .
i made this video some years ago. you can download the softwear for free. just google audacity.
