$$ \Delta V_{AB} = \int_{r_a}^{r_b} \mathbf{E}\cdot d\ell $$
Most signals are typically $\pm5\,V_{pk}$, $10\,V_{pp}$. Audio signals being bipolar (duh) AC, and CV signals usually being unipolar (0V to 10V) or bipolar (-5V to +5V) DC signals. Additionally, CV and Audio signals in theory can mix, but usually don't (unless the wave is a simple waveform).
