ReaEQ

ReaEQ is an exceptional parametric EQ plugin that is lightweight, transparent, and highly precise. It can be downloaded for free as part of the ReaPlugs VST FX suite by Cockos. One of ReaEQ’s standout features is its virtually infinite flexibility. The plugin offers unlimited bands and an extensive range of filter types per band. These include shelf EQ, band EQ, low-pass, high-pass, band-pass, all-pass, and notch-pass filters.

If you’re looking for a surgically precise and transparent parametric equalizer, ReaEQ is one of the best options available for free. It is also lightweight, allowing you to run multiple instances simultaneously without straining your CPU. The interface doesn’t look fancy, but it is very user-friendly. It provides easy mouse controls and modifiers for editing the bandwidth of points in the graph, which significantly speeds up the mixing workflow.

ReaEQ also offers frequency and phase response displays, along with a note and octave display for frequencies, enhancing the overall user experience. Because of its CPU efficiency and ease of use, I use ReaEQ as the main EQ on my portable DAW. It’s also my go-to EQ when mastering individual audio files while working on sample packs. The unlimited bands and precise controls are extremely handy when removing unwanted frequencies and resonances from rendered WAV files.
