2 summary:: Zero crossing frequency follower
3 categories:: UGens>Analysis>Pitch
6 Outputs a frequency based upon the distance between interceptions of the X axis. The X intercepts are determined via linear interpolation so this gives better than just integer wavelength resolution. This is a very crude pitch follower, but can be useful in some situations.
