Cue-Ball Velocity Measured Acoustically
High cue-ball speed to break the pack is essential - the velocity is easily measured

Set up a laptop running Goldwave audio software or similar, with a microphone. Accurately measure the distance between the cue ball and the object ball (the centre of the first ball of the pack).

Start recording

Aiming directly at the object ball, break.

Stop recording

Either by slowing up the sound of the break, or by zooming into the waveform visually, determine the start points of the two distinct sounds:-

The tip of the cue colliding with the cue ball

The cue ball colliding with the object ball

Determine time between the noises

Velocity = distance / time
