  We present STEREO observations within 1500 proton gyroradii of 12
interplanetary shocks, with long-duration burst mode electric field acquisition
by S/WAVES enabling observation of the evolution of waves throughout the entire
ramp of interplanetary shocks. The shocks are low Mach number ($M_{f} \sim
$1--5), quasi-perpendicular ($\theta_{Bn} \geq 45^{\circ}$), with beta
($\beta$) $\sim $0.2--1.8. High variability in frequency, amplitude, and wave
mode is observed upstream, downstream, and in shock ramps. Observations in
every region include ion acoustic-like waves, electron cyclotron drift
instability driven waves, electrostatic solitary waves, and high frequency
whistler mode waves. We also show for the first time the existence of
"dispersive" electrostatic waves with frequencies in the ion acoustic range and
the first observations of electron cyclotron drift instability (ECDI) driven
waves at interplanetary shocks. Large amplitude waves are bursty and seen in
all three regions with amplitudes from $\sim$5 to $>$ 200 mV/m. All wave modes
are more commonly observed downstream of the shocks than upstream of them,
usually within $\sim$ 63000 km ($\sim 1500 \rho_{gi}$) of the ramp.
