Break Speed Tool

Table Size

Playing surface length used for distance calculation

Cue offset (cm)

How far behind the head string your cue ball is when struck

Mic placement

Where your device is placed relative to the table

Room temperature (°C)

Used to estimate speed of sound

Auto threshold

Estimate noise floor and set detection threshold

Onset threshold

Derivative threshold for transient detection (0.060)

Min RMS

Absolute minimum RMS to consider a sound

Sensitivity

Lower = more sensitive (threshold 0.060)

Debug logs

Log detection details to console

Auto reset after result

Continue measuring without restarting mic

Results

Distance: 1.37 m

Speed: — m/s

Speed: — km/h

Speed: — mph

Assumptions: cue ball is struck at the head string, distance to rack apex is approximately half the table length plus your cue offset. Times are corrected for sound travel based on mic placement and temperature.
