What is a Dynamic EQ?

A dynamic EQ is an audio processing plugin that combines features of both an equalizer and a compressor. It adjusts specific frequency ranges only when those frequencies exceed a defined level, allowing more precise control over the tonal balance of an audio signal.

Unlike a traditional EQ that applies constant boosts or cuts to frequencies, a dynamic EQ responds to the incoming audio signal. When a selected frequency band becomes too loud, the plugin automatically reduces it according to parameters such as threshold, ratio, attack, and release. When the signal drops below the threshold, the EQ returns to its neutral state.

Dynamic EQ is commonly used in mixing and mastering to control problem frequencies without affecting the entire signal at all times. For example, it can reduce harsh vocal frequencies, control boomy bass notes, or tame resonances only when they become excessive, allowing the rest of the audio to remain natural and balanced.
