There are two main ways to measure audio levels: Peak and RMS (Root Mean Square). Peak measures the highest level the audio produces (even incredibly short duration peaks) — thus locating peaks in a signal, while RMS quantifies the average level of a signal. RMS correlates more closely to our hearing.
