Timing calibration for acoustic speed measurements
= Timing calibration for acoustic speed measurements
{title2=$\Delta t=d/c+\tau_0$}
<Timing calibration for acoustic speed measurements> separates travel delay from the offset $\tau_0$ between acquisition channels and checks the clock defining the <sampling rate>. A constant offset changes the intercept of a delay-versus-distance <linear regression>; a clock-scale error changes the inferred <speed of sound> itself.
