# 3-band Equalizer

An audio equalizer (EQ) is a tool used to adjust the balance of different frequency components in an audio signal. It allows you to boost or cut specific frequency ranges, shaping the overall sound.

The 3-band Equalizer equalizer with variable **frequency**, **gain** and **Q** (width) settings. The input gain and the gain for each band can be adjusted from -36 dB to +36 dB. If the signal is overloaded (>100% dbfs), the warnings section will indicate the peak output value (dB).

          Note

          

This operator displays the audio **input level** before processing and the **output level** after the operator has been applied, allowing you to monitor how the adjustments affect the signal.

A miniature audio meter (VU meter) in the header indicates incoming audio, so you can quickly verify that the operator is receiving audio even when it is collapsed.

### Warnings

- **Signal Overload** – If the peak level exceeds 0 dBFS, the signal overload indicator will be active for two seconds.
- **Peak Overload (dB)** – Shows the last measured peak value in dBFS.

          Tip

          

Use [Settings](/docs/settings-audio) to adjust how long the signal overload indicator stays active, and [Project Options](/docs/runtime-performance) to change the maximum peak level displayed in all audio meters to your preference.

For more information on audio, see [Working with audio in scenes](/v1/docs/working-with-audio-in-scenes).

(The operator is available in R1 2025 and later releases)
