Ratio controls how much the compressor turns down signal above the threshold.
A 2:1 ratio means that for every 2 dB above the threshold, roughly 1 dB comes out. Higher ratios reduce level more strongly and move closer to limiting.
Ratio only matters once the signal is crossing the threshold, so it works together with input level and threshold setting.
Lower ratios are common for smooth vocal, bass, and bus leveling. Higher ratios are useful when peaks need firmer control or when compression is part of the sound.
A high ratio with little gain reduction may be subtler than a low ratio driven hard, so the meter matters.
Watch how many decibels of gain reduction happen during loud moments and how the output peaks respond. The ratio number alone does not describe the result.
Meter Core helps you compare loudness and peak movement after ratio changes so the setting serves the mix instead of just getting louder.
